INTRODUCTOIN
Banking is the interesting subject. It provides some important or special services to their customers. Bank
Provide saving money, It gives loans to their customer
Or some other facilities like ATM cards, CREDIT cards.
Banks offer the customer to open new account in the bank. Accounts are two types like single account and
Joint account. Single account has one owner where as Joint account has two or three owner. Bank also offers checkbook facility to the customer.
Following are some rules you followed when you open a new account in the State Bank of India:
1. Please DO NOT Introduce any person to the Bank for propose of opening an account unless you know him/her well.
2. The attention of the depositor I invited to the Saving Bank Account rules, which govern the conduct of the Savings Bank Accounts. A copy of the rules may be called for, if not already received.
3. For facility of the depositors, certain extracts from the rules concerning the importance of the pass book and governing the mode of withdrawals have been reproduced at the end of the pass book.
4. Nomination facility is available.

6.Account Holders should examine the entries carefully made in their passbook and draw Bank’s attention to any errors or omissions that may be discovered. The Bank will not accept any responsibility for any loss arising out of his failure to carry out examination of entries in the passbook not authenticated under the initial of its authorized officials.
7.THE PASS BOOK MUT BE PRESENTED OR ALL WITHDRAWALS OTHER THAN BY CHEQUES Deposits may be made without the production of the passbook. The Account Holders should ensure that their passbook is presented at intervals for updating. A passbook tendered while transacting or for completion of entries will be made-up and returned to the Account Holders or to their authorized representative the same day. If left overnight, the Bank will issue a receipt in the form of a paper token which must be surrendered in exchange of the passbook within a week, failing which the Bank will dispatch the passbook to them by registered AD post as their costs.
8. The account Holders should keep their passbook and cheque books in a place of safety. The Bank will not be responsible for any loss or incorrect payment attributable to the neglect of this rule.
9. If a passbook is lot or spoiled a cheque of Rs. 20/- will be levied for a duplicate passbook, which will be issued only after due enquiry. Additional charge of Rs. 20/- per ledger folio (40 entries) will be collected for copying the previous entries.
10. Cash deposit for less than Rs. 10/- will not be accepted, exceptions being made for transfer credits and instrument
Lodged for credit of the accounts. Accounts Holders are advised to preserve the duly stamped and acknowledged counterfoils of the day in slips at leat till the relative entries are made and authenticated in their pass books
11. In satisfactorily conducted accounts immediate credit will be afforded for outstation instruments for account upto Rs. 15,000/-.
12.Bank`s standered withdrawal form must be used for withdrawing monies otherwise then by cheques, Withdrawal forms cannot be used for making payments to third parties.Amount smaller than Rs. 50/- cannot be withdrawn and all withdrawals must be multiple of rupee one only.For withdrawing monies through authorised representative a letter of authority (In the prescribed form) duly signed should be presented along with the passbook. The thumb impression of the illiterate Account Holders on the letter of authority should be attested by two persons known to the bank or by a magistrate under his court seal.
13. Cheques must be written legibly and all alterations/cuttings must be authenticated under full signature of the Account Holder. Cheques should be drawn in a way as to prevent any alterations or insertions after their issue.
14.The Bank will register top payment instructions from the Account Holders in respect of cheques lost, stolen etc, but cannot grantee the against loss in the event of such cheques being paid inadvertently.
15.A Service charge of Rs.2/- for MICR cheque room and Rs.1/- for non-MICR cheque form will be recovered for cheque forms issued in excess of ixety in a calandar year.
16.The maximum number of debit entries (by withdrawal, cheques or letters) permitted in an account is fifty per half year. A SERVICE HARGE OF Rs.10/- per extra entery in excess of the ceiling will be debited to the account at the time of yearly application of interest.
17.A service charge of Rs. 50/- p.a. will be recovered in respect of accounts remaining inoperative (no deposit and no withdrawal) for a continue period of twenty-four months. This charge will be recovered only in account having balances below the stipulated minimum in term. If the balance is equal to or less than Rs. 50/- the account will be acepted for a normal charge of Rs. 25/-.

Identification of need
Developing a system is just like a manufacturing unit where some raw material and man power is used to produce the goods – in computer system, the data and fed to computer for processing. The results produced by figures are computer is called information and have value of its users. On the basic of information we can take valuable decisions.
In the later 1980, this process it was known as Computerization, but in 1990s it’s name is more popular under the title “Information Technology”. According to an author Peter Norton, the amount of information we have produced from 1990 to till today is much much more than what information we have produced in last 3000 years. So like industrial revolution, milk revolution and and green revolution – there is a revolution in field of Computers – so that’s why it becomes an technology called “Information Technlogy”.
A system is defined as the organized collection of components works in a coordinated manner, to achieve an objective. There three main implications of a system i.e.
1. A system must have a predetermined objective(s).
2. There must be interrelationship and interdependence among the system components.
3. The objective of organization as whole has higher priority than the objective of an individual component.
Characteristics of a system :
1. Organization : It means all the parts of a software system must be properly arranged in order and structure.
2. Interaction : All the components of a system must interact with other components to achieve the objective.
3. Interdependence : One part of a system must depends upon other component for proper working. It means the output of one part may be feed to the other component as input.
4. Integration : It means holism; which means the collection of all the components.
5. Central Objective : Each system must have one central objective.
Components of a system
1. Output and input : The output are the outcomes of a system and input are the data, figures and raw material fed into computer for processing.
2. Processor(s) : It is the operational component of a system. In an industry, plant & machinery is used to convert the incoming material to the finished goods – but in a computer system; operating system, language & DBMS package helps the user to convert the input data into output data.
3. Control : It is the decision making subsystem of a system. It deals with management of resources and other components; Operating system.
4. Feedback : A feedback may be –ve or +ve. These feedback factors gives the idea to improve the system.
5. Environment : It is the supra system in which system operates; like users, offices and labs.
6. Boundaries and interfaces : It is the limit which help us to identify the system components.
stages of a life cycle :
Like Nitrogen & Production cycle – a Software system is just like a cycle which passes the following stages like:
1. Recognition of need.
2. Feasibility study.
3. Analysis.
4. Design.
5. Implementation & Maintenance
1. Recognition of need : This steps is to be taken by the authorities of the organization. The old system has many limitations, which will be discussed in the system analysis part of this project. The Initial Investigation mainly deals with
· Recognition of need
· Ability of users
· Finance involved
· Current system and how new system will rectify the problems of old one.
· It is also possible that an old or computerized system can be replaced by computerized in the SAD.
2. Feasibility Study : This study deals with : Technical Feasibility . It is related with the technical specifications of the projects. It focus on the three major questions : Hardware & software available in market
H/W & S/W required Potential of the hardware.
Economics Feasibility : It deals with the cost benefit analysis. It includes the expenses like H/W, S/W, installation cost, furniture, fixture, wages, salaries etc.
Operational Feasibility : It basically concern with the operational environment capabilities of a project. It focus on ability of users, user friendliness of the projects, nature of working environment provided & ergonomics.
3. Analysis : Analysis is the study of checking the relationship of components with the environment and other parts of the system. This stages deals with “What is to be done to design the candidate system ?”.
4. Design : It is the most creative and challenging phase of system development. It deals with converting input into output. It contains output design, input design, file or database design and processing design.
5. Implementation & Maintenance: It is the less creative stage of life cycle in which new system will replace the old system completely or partially. There are three types of conversion : Direct, Phase wise and pilot. It also deals with backup, recovery, security and reliability measures of the cycle.
Preliminary Investigation
Previous System.
Fact finding means to trace the following factors in the field of SYSTEM ANALYSIS AND DESIGN. The fact finding passes through the following stages.
1. To check the performance of old system.
2. Problems in the
3. Old system.
4. Recommendations which can rectify the problems.
5. The management biases.
6. The user limitations.
7. Present hardware and software.
8. Finance
Fact-finding is also called feasibility study. SYSTEM ANALYSIS AND DESIGN is just as a manufacturing unit in which raw material is entered as input, machine and plant work as process and products/finished goods as output. In the SAD the raw data is the input, programs is the processes and information is output. Some time if the information is not up to the standards then the output can be fed to the system as input - It means it work as a cycle. So that why SAD is also called SDLC i.e. System Development Life Cycle. During the system analysis, it is found that the old system is the manual system. The old system has following advantages
1. It was very difficult to maintain the bills, complaints register, subscribers’s reports and bulky bills preparations.
2. No automated tool like COMPUTER is used for the processing.
3. It is difficult to get the prompt case position.
4. Difficult to keep the provide ON-LINE information to the management, customer, clients & subs.
5. More staff was required.
6. Old system has following limitations
1. Not up-to-date
2. Less security
3. Data duplicacy
4. Not centralized
5. Slow in process
Proposed System.
The new recommended is the computerized, which has many advantages over the old one.
1. Since the overall system is under the control of Data Base Administrator (DBA) - hence the system us centralized one.
2. The security and privacy is more in case of new system.
3. The long process can be shortened.
4. Easy to maintain the reports
5. One deletion can delete all the related enteries.
6. Each to check the consistency of entries.
7. Fast in process as compared to manual system.
Feasibility Studies.
There are three feasibility studies : Technical, Economic and Behavioral or Operational . Feasibility is the most successful system projects are not necessarily the biggest or most visible in a business but rather those that truly meet user expectation. FEASIBILITY CONSIDERATION:
ECONOMIC FEASIBILITY: Economic analysis is most frequently used method for evaluating the effectiveness of candidate system. More commonly known as cost and benefits analysis.
TECHNICAL FEASIBILITY: Technical feasibility centers around the existing computer system (hardware ,software,etc.) and to what extent it can support the proposed addition. For example, if the current computer is operating at 80% capacity-an arbitrary ceiling- then running another app. could overload the system or require additional hardware.
BEHAVIORAL FEASIBILITY: People are inherently resistant to change, and computer have been known to facilitate change. An estimate should be made of how strong a reaction the user staff is likely to have towards the development of computerized system.
STEPS IN FEASIBILITY ANALYSIS::
1. Form a project team and appoint a project leader
2. Prepare system flowcharts.
3. Enumerate potential candidate system
1. Describe and identify characteristics of candidate system
2. Determine and evaluate performance and cost effectiveness of each candidate system.
3. Weight system performance and cost data.
4. Select the best candidate system.
5. Prepare and report final project directive to management.
Data Collection is very important for designing a system. To design a system – we must collect the information about
Information about the organization:
Policies
Goals
Objectives
Organization Structure
Information about the user staff who will use our project directly or indirectly:
Authority
Relationship
Job functions
Interpersonal relationship
The information about work:
Work Flow
Work methods and procedures
Work Schedules
To collect the information, some data sources are required and they are :
INTERNAL TOOLs : - Which are used to collect the data from sources within the organization and they are:-
1. Financial Reports
2. Personnel Staff
3. Professional staff
4. System documents and manuals
5. User staff.
6. Reports transaction documents.
EXTERNAL TOOLs : These are the outside tools used to collect the data from the system for designing and they are
1. Vendors.
2. Government documents.
3. Newspapers and professional journals.
To collect the data properly, some tools are used and they are :
1: Review of literature, procedures, and forms.
2: On-site observations.
3: Questionnaires.
4: Interviews .
Review of literature, procedures, and forms : In this tool the old documents of organization are studied – in this tools; we get old forms, old bills, old slips, manual registers etc. The major advantage of this tool is that we can get data in bulk and we can design screen as appear manually – but the data may be too old and some new changes are not included in that.
On-site Observation : In this tool, the analyst and user visited the organization and collect the samples and data. The major advantage of this tool is that we can get fresh data and know the system working “How the old system works actually ?” – so that equivalent candidate ( computerized ) system can be developed. But it is also possible that many organizations may not allow you to observe the actual system and you may pick the wrong sample.
Questionnaires : In this tool, some set of questions are sent to the users. These questions may be option selection based, open ended questions, yes/no questions and essay type questions. After filling these questions ; they are returned to the programmer or analyst. It looks an easy tool but there are very less number of returns.
Interview: It is the best data collection in which one person asks the questions and other answers. It is the fast and accurate method. I use this method in my project.
Structured analysis means tools used to understand the system easily and steadily. These tools are
ü Data flow diagrams
ü Data Dictionaries
ü Structured English
ü Decision Trees
ü Decision Tables
ü ER Diagrams
DFD is a tool which show the actual data flow in the system. It show us various points from where the data is flows to a new point and where the major transformation takes place. The DFD uses some symbols and they are
A Square represents the source or destination of data.
A Circle represents the program name or process.
A Solid Arrow Line shows the data in flow or motion.
An Open Rectangle shows the data at rest.
Data Dictionaries : Although DFD represents the data flow and transformation; but still it does not indicate the full details of the system. For getting more details; data dict is used. A DD represents data about data. It is a document which is used for system documentation and reference. It contains all the details of elements. The root of the tree is called problem name.
Decision Table : A decision table is the collection of four quadrants; condition stub, action stub, condition entries and action entries. In condition stub all the condition are listed in simple English and Maths. In Action stub all the actions are written, In condition entry the responses to the conditions are written in ‘Y’& ‘N’ form. In Action entry all the action response is written as X & --. ‘X’ means action taken and ‘-‘ means no action.
ERD : Entity Relationship Diagram is a tool used to represent the tables, their attributes and relationship.
Since SDLC is a cycle. It is called cycle; because after some time your project may be terminated and initial investigation is done again ( i.e. first stage of the SDLC ). The project terminated in the following situations. So an analyst and programmer must take care of these factors:
* Changing objectives or requirements of the user can not be met by the existing design.
* Benefits realized from the candidate system do not justify commitment to implementation.
* There is a sudden change in the user’s budget or an increase in design cost beyond the estimate made during the feasibility study.
* The project greatly exceeds the time and cost schedule.
* User requirements were not defined clearly or understood.
* The user was not directly involved in the crucial phases of system development.
* The analyst, programmer, or both were inexperienced.
* The systems analyst or the project team had to do work under stringent time constraints.
* User training was poor.
* Existing hardware proved deficient to handle the new application.
* The new system left users in other departments out of touch with information that the old system had provided.
* The new system may not user-friendly.
* Users changed their requirements.
* The user staff was hostile.
Man has invented many electronic devices but computer has a greater Impact on society than any other device. They have made a potentially significant contribution to the society during the last three decades. One of the primary reasons for the immense popularity Of computers is the speed with which they can accomplish specified task.
However computer application are not always easy to use. Any application has two parts:
- USER INTERFACE
This is the screen displayed by application .we interact with an application via the interface. Every application has a user interface in one form or the other. The application asks for and we provide the necessary instructions using the interface.
2. PROGRAM
Computers need clear-cut instructions to tell them what to do and, how to do and when to do. A set of instructions to carry out a specific task is called a program. This is what goes on the background.
Applications generally provide two types of interfaces :
Character Based Interface Graphical User Interface
2. Character Based Systems
In a Character Based System, text was the medium of information exchange. The application displayed text that prompted the user for the required information. It also specify the valid options, if any. The user then responded to these prompts by specifying the required information.
Such an application is not very easy to use, essentially because the user cannot react intuitively to this interface. The disadvantage with Character Based Systems was that each new application the user had to spend time and effort getting used to the way it worked.
2.2 Graphical User Interface
Interfaces that use graphics came to be known as Graphical User Interface. These became very popular because the users could identify with the graphics displayed on screen. In everyday life too, we associate more with images than words. Such an interface presents the user with an intuitive way of interacting with the application.
2.3 THE NEED FOR VISUAL PROGRAMMING
There are several programming tools that allow us to build such visually appealing and intuitive interfaces. These tools allow us to design interfaces that employ user-friendly features such as buttons, menus, windows etc.
However the disadvantage of such tools is that the interface is designed using code. The programmer has to code the user interface features specifying the size, position etc. this makes designing the user interface major task in itself.
Therefore a programmer spends a lot of time writing code for the user interface. Moreover large percentage of the user time is wasted in action of writing the code, aligning the buttons properly.
This means that if the process of building the user interface
is simplified, then the time and effort required in developing an application can be reduced. There is the need of an environment that would allow easy design of the user interface. Thus was the born the art of VISUAL PROGRAMMING.
2.4 Rapid Application Development (RAD) Tools
RAD tools help us to create applications in a shorter time as compared to conventional languages and with fewer errors.
RAD tools help us to create a range of applications. These could range from a small utility for ourselves or even distributed applications spanning the globe in the internet.
2.5 WHAT IS VISUAL BASIC
VISUAL BASIC is Microsoft’s RAD (RAPID APPLICATON DEVELOPMENT TOOL) for windows programmers. RAD tools help us to create application in a shorter time as compared to conventional languages and with fewer errors. Visual basic uses a graphical, forms-based approach to application development. The typical way to write a program in visual basic is to create a form, drag and drop controls onto the form, set properties for the form and its controls, and add application-specific code to handle events. It sounds simple, but we can write some very popular applications in this manner.
VISUAL PROGRAMMING:
A visual programming environment provides all features that are required to develop a graphical user interfaces as ready-to-use components. The programmer does not have to write a code to create and display commonly required user-friendly features each time around.
A visual programming environment automates the process of creating a user interface. The interface provided by this is called the VISUAL INTERFACE. Using the visual interface the programmer designs the user interface visually instead of writing code. In addition it also provide a means of associating code with each component. In visual programming the component can be moved, resized and even deleted if so required. There is no restriction on the number of controls that can be placed on a form.
Some popular visual programming tools are:
Visual basic Power builder Developer 2000
SOME VISUAL INTERFACE
COMPONENTS
Having been introduced the concept of visual programming, we now explore some often used visual interface components.
WINDOW
A window sometimes also called a form, is the most important of all the visual interface components. A window plays a role of the canvas in the painting. Without a canvas there is no painting similarly, without the window there is no user interface. When an application starts it opens a window.
BUTTONS
The button also referred as command button or the push button, is one of the most popular user interface component. A button is used to initiate an action. The text on the button indicates the action that it will initiate.
TEXT BOXES
Text boxes are used to accept information from the user. The user interface will display one text box for each piece of information. The text box is a means of accepting information from the user.
LIST BOXES
List boxes are used to present the user with the possible options. The user can select one or more of the listed options.
DEFAULT FUNCTIONALITY OF THE INTERFACE COMPONENTS
The ready-to-use interface component supplied by a visual development incorporate certain default behaviour. The default behaviour can be altered to meet the requirement of the application. Similarly, the component also have default properties.
For example: A button always has a default caption, which is the text that appears on the face of the button. The user can change the text. All controls have names associated with the every interface component are certain characteristics which can also be referred as properties. These properties are set to default when the component is created. A major part of the interactions between people in the every day life is in the form of events and responses to events. An event is any user action directed at the application. Interface component have the ability to respond to the events. An event driven application operates by responding to the user events.
A method is the code that is build into the interface component and can be executed as required. For example, consider a list box. A list box component will provide a method called add item. This method is to be executed every time an item is added to the list. Similarly, most controls provide a method called move that can be used to reposition the control during the course of execution. This feature is required very often in the application that provide animation. Each component can have several methods associated with it. Each method provides distinct functionality.
VISUAL BASIC CONTROLS
THE FORM: The window is called a form in visual basic. The form is the main part of the user interface. It is the base on which the user interface is built. Every windows application must have at least one form.
THE FORM PROPERTIES:
Forms have the properties that determine aspects of their appearance, such as position, size, and color; and aspects of their behaviour, such as whether or not they are resizable. Listed below are some of the important properties of a form.
CAPTION: The text that appears on the title bar of the form. When the form is minimized this is the name that appears below the form’s icon.
NAME: Text used in the code to identify a form. the default name for a new form in visual basic is ‘form’ plus a unique integer. For example, the first new form has the name form1,the next form2 etc.
FORM METHODS
We can develop applications that efficiently use the computer resources Such as memory and processing speed by understanding the form’s method. We use the following methods to manage forms in visual basic.
1. LOAD
2. UNLOAD
3. HIDE
4. SHOW
1. LOAD: The load statement initializes and loads the form into memory without displaying it on the screen. If a form is not already loaded, any references to the form automatically loads it into the memory.
E.g. load form1
UNLOAD: unload removes a form from the memory. Unloading a form may be necessary to free the system’s resources, and to reset form properties to their original values. A form can be unloaded as follows:
unload form1
or
unload Me
The Me statement refers to the current form of the application.
3. HIDE: The hide method removes a form from the screen. A user cannot access a hidden form’s controls but the Visual Basic application has access to it. The user can interact with the form only after the code that caused the form to be hidden is executed completely. When a form is not loaded into the memory and the hide method is called, it loads the form but does not display it. A form can be hidden in the following two ways:
Form1.Hide
Or
Me.Hide
SHOW: The show method loads a form into memory if not loaded already and displays it on the screen. This method displays forms modally or modelessly. A model window requires the user to take some action before the focus can change to another form. The default argument for the Show method is modeless. We use the show method as follows:
Form1.show vb model.
THE COMBO BOX OR DROPDOWN LIST BOX:
A combo box control combines the features of a text box and a list box. This control allow the user to select an item either by typing text into the Combo box, or by selecting it from the list. Combo box present a list of choices to the user such that only the selected item is displayed while the Rest of the list is hidden.
THE RADIO BUTTON OR OPTION BUTTON
The radio button, also referred to as option buttons, are used when the User can select one and only one of the multiple options.
THE FRAME CONTROL
The frame control can be used to separate option into group. Once this is done, it is possible to select one option button in each group. The frame Is essentially meant to be a container for all other controls. Thus it does not have any unique properties. One property of the group box, that is Important is caption: the text that appears on the frame.

Items or a large amount of information. They can also be used minute measurements such as controlling the volume of a computer game. Scroll bars are actually Graphical representation of numeric values. The visual basic allows you to Create two types of scroll bars: horizontal and vertical. Horizontal scroll bars scroll from left to right and vertical scroll bars scroll from up and down.
THE LABEL:
The label is the control used to place text in a form. The main difference between a text box and a label is that a user can modify text box but cannot modify the text in the label. Typically, label is used to identify Controls that do not have a caption property of their own. For example, a text box.
INTRODUCTION TO ADO
There is an increasing popularity of distributed application and databases In the IT industry. A distributed application is one that has two parts:
FRONT END
BACK END
FRONT END that runs on the client computer
BACK END that runs on the server.
In distributed applications, the main aim is to divide the computing into two parts. The front end requires minimal resources and runs on the workstation of the client. The back end requires large amount of data or specialized hardware and runs on the server. A connection between the client and server allows data to flow in both directions.
With the need and popularity of distributed application and the different formats in which the data is stored there was a need to have a mechanism that sported these applications and databases. As a solution OLE DATABASE brought a new approach of accessing data.
OLE DATABASE IS A DATABASE architecture that enables the application to have Uniform access to data stored in the diverse information sources, regardless of the location or type. OLE DATABASE defines a set of COM(component object model) interfaces that enables a uniform access
To data stored in diverse DBMS. An interface is a class with all functions abstract.
DATA ACCESS IN VISUAL BASIC
Visual basic provides three data access interfaces. They are:
1. DATA ACCESS OBJECTS(DAO)
2. REMOTE DATA OBJECTS(RDSSO)
3. ACTIVEX DATA OBJECTS(ADO)
ACESSING DATA WITH THE DATA CONTROL
ADO is an interface to OLE DATABASE, introduced in version 6.0 of the visual basic.
This is Microsoft’s newest data access technology and provides access to almost any data stored in different formats. ADO is a replacement for the older DAO and RDO and gives you us features not found in either. for example it also allow us to access other data sources such as, e-mail, file systems, project management tools and spreadsheets. The ADO DATA CONTROL is the key element in creating data access application with a minimum of code. It provides a visual interface for setting data access properties. It provides a link between an application and the data we need to access. We create this link by placing the ADO data control on a form by binding controls to ADO data control without writing any code. Controls can be found to the ADO data control if they possess the data source property. These include the check box, image, label, textbox controls.
CONNECTING A DATA SOURCE
We create a connection to a data source by setting the connection String property of the ADO data control. This property specifies the type and location of the database that we need to access. To set the property we click the ellipsis button next to the connection string property in the properties windows of the ADODC.
THE RECORD SOURCE PROPERTY.
The record source property specifies where the records will come from after a connection is established to a database. This property can be set to a table name, a stored procedure or a SQL statements. It is a good Practice to use a SQL statement, which retrieves only the selected rows From a table rather than selecting an entire table.
CREATING A RECORDSET
After getting connected to a database and learning how to display information from the database in the bound controls we now learn to manipulate data with the ADO data control. The record set property of the ADODC is an object that represents the entire set of records from a table or the results of an executed command. The record set object is used to access the records returned from a query. At a given time a record set object points to a single record called the current record in the set of records returned from a query.
We use the record set object to do the following manipulations to the data in the database:
ADDING RECORDS.
MODIFYING RECORDS.
DELETING RECORDS.
FINDING SPECIFIC RECORDS.
ADDING RECORDS:
We use the AddNew method to add the records to a record set. When we add a new record , the ADODC clears the information in the bound controls to prepare them for the addition. The following code adds a new
Record:
AdoEmpolyees. Recordset .AddNew
This record becomes the current record. the new record is added to the database when we move to another record. This action prompts the ADODC to save the new record to the database. To cancel any changes made to a record we use the CancelUpdate method.
MODIFYING RECORDS:
The ADODC automatically modifies records when we move to the record that we wish to change. Make the necessary changes and the move to the next record. We can also use the update method to modify the current record.
DELETING RECORDS:
The delete method of the record set enables to delete a record. The record is removed from the database but the bound controls still displays The information of the deleted record until we reposition the record pointer to another record.
FINDING RECORDS:
Searching for a specific record requires invoking the find method of the record set and specifying the condition for the search. When we use a string value in the find method, the value is to be enclosed in the single quotes.
WORKING WITH ACTIVEX DATA OBJECTS
We can creat more powerful application using the ADO objects than we can using the ADO data control. Though ADO data control allows us to navigate and edit records ADO objects provide us all the data access and manipulation features required by the most applications.
Some of the advantages of using ADO objects than using the ADO data control are:
Validation of any information entered by the user before it goes into the database.
We can create database applications that do not require a user interface. Since the ADO data control is a graphical component, it can be used only in programs with a visual component.
We can use SQL statements to modify multiple records at a time.
The ADO object model has the following three main objects that are required to access data from an existing database.
Connection
Recordset
Command
CONNECTION
When we work with data in a database, we must first create a connection to the data source. The connection object makes a connection between an application and the data source such as Microsoft SQL server. Each connection object supports multiple lower level objects such as RecordSet objects and command objects. Creating a connection object is similar to the setting the ConnectionString property of the ADODC.
RESCORDSET:
A RecordSet object represents the entire set of records from a table or the results of an executed command. The RecordSet object is used to access records returned from a query. We manipulate the data almost entirely
Using the RecordSet objects. This object is constructed using records and fields.
COMMAND:
We use a command object to query a database and access the records that are required from the database. The records are returned in the RecordSet object. Command objects can be used to create a RecordSet object and obtain records, to execute a bulk operation, or to manipulate the structure of the database.
INTRODUCTION TO ORACLE 8
We are using ORACLE 8 as a back-end in our project. ORACLE 8 is the most popular database currently in use.
Various approaches to data management are:
- Manual methods of data management
- Management of data and information
- Convenient and efficient retrieval
- Updating operations
- Limitation of manual data management
- Physical Volume of data
- Human processing of data
- Technological Advancement in data management
- Using computers to speed up processing of data
- Advancement of processing power
- High speed storage devices
- Centralized to distributed databases
Database management : An Evolutionary Phenomenon Drawbacks of the prevalent approach to data management
· Data redundancy
· Risk to data integrity
· Data isolation
· Difficult access to data
· Unsatisfactory security measures
Poor support of parallel access of data
Concept of a DBMS
A database is a collection of interrelated data from which some information can be extracted. The collection of data must be logically coherent with some inherent meaning. A database is designed and Built for a specific purpose, keeping in mind the needs of the applications that are going to use it and the end users of those applications. It is managed bysoftware package known as a database management system(DBMS). Data is stored in the form of tables. Tables are then connected with visual basic and through linking this Can be used in front end in the project.

Code Efficiency
The code efficiency of a project can be improved by using
· Functions
· Pointers
· Standard Exe codes
· User Defined Functions
In this project most of the coding is done on the basis of these principals, hence the codes in this project is relatively efficient.
Validation checks.
ü All the primary key fields Should not be 0 or -ve or repeated
ü If vcnh no or acc code number is zero or not found the print error.
ü After specified amount in cash, voucher should not be posted.
ü In case of cash in hand s zero or negative then no cash issued to chqeue issued entry is to be executed.
After due date – computer should prompt for submitting the tax return
Testing & Implementation Techniques
There are three mainly used testing and implementation techniques,
Parallel or Pilot. Direct
In Direct conversion - on a particular day the old system is discarded and new one is adopted. Although it is a fast process but if only system is to be consulted but that is not available. In parallel model, the old system can run in parallel manner. Both the system can be tested and consulted for accuracy, but this system is costly one - because it is required to run the system parallel which is a time consuming and costly.
Hence the third system is to be consulted in which the old system is to be converted into new one phase by phase. In this project phased model is used.
Security Measures & Maintenance
Even after the proper analysis and design - once a system has been implemented - even then some security and maintenance measures are to be taken , so that system data can be avoided from theft, disclosure and intentional misuse. Following points should be kept in mind
1. The entry to the system is to be done thru proper channel like DBA or system manager.
2. Each user is assigned a time constraint, a user name and a password.
3. Each used should lass with different type of privileges.
4. Daily Virus scanning is to be done.
5. Daily backup on tapes, CDs, thumb drives & Zip disks is to be taken.
6.Data must be secure - when it is in the organization, in transportation and under communications.
COST ESTIMATION, PERT
& Gantt Chart
The PERT ( Program Evaluation and Review Technique ) deals with how project is proceeded with the passage of time and various possibilities of the problem solution. 
Hire a programmer Develop
1
Define Problem 2 Purchase Implement 
s
3 Develop in-house
Activity Time estimation Cost Estimation Recommendation
1 6 Months 25,000/_ Accepted
1 1 Year 50,000/_ Not Accepted
1 1 Years Or MOre 60,000/_ Not Accepted
GANNT CHART will show how the project grows in all the stages ( as shown in the worksheet with a bar chart ). COST Estimation is about Rs. 25000/_ as per PERT & GANTT.
Future Applications of the project
ü Since this project is linked with the Internet. So any time we can send mail to the supplier, customers, market and committee.
ü Since Oracle 8i is a powerful RDBMS, So the s/w can be also be accessed using other programming languages i.e. GUI tools like X-WINDOWS tools.
ü The URL of the VB6 & Oracle 8i can be connected for E-Commerce purpose.

Glossary
1. Computer Sc : It deals with theory and implementation of Computer Sc.
2. Visual Programming : It deals with GUI based program.
3. Back End : A back end tool is used to store the database at back end and manipulated by the front end.
4. Front End : A front end reduce the program efforts and helps in RAD( Rapid Application Development ).
5. OLE DB : A tools used by Oracle and Visual Basic to handle the database connectivity and ACTIVEX programming.
6. EXE File : It is ready to run file and hide the code. It can be plat form independent.
7. Database : A collection of information store under one name.
8. RDBMS : Relational Database Management System. Helps the user to relate the tables with minimum redundancy and integrity.
Conclusions
1. This project require a programmer, costly hardware and more data security options are to be applied.
2. The database can be easily trapped if the data base is not secure under the control of DBA.
3. Centralized control is must.
4. It may require 6 more months for analysis, design and implementation.
5. The project may be rejected after implementation - if it is not correctly analyzed and designed I.e. user requirement is not clearly defined.
6. If it is used properly, it can give accurate results with speedy process.
7. It can reduce the paper work, staff requirements and threats to the data security.
