1. INTRODUCTION In the modern era, computers have made everything under one root and have knit the World together. Even the complicated and time consuming works are made nothing by the Computers. Because of the technological IT revolution computer has been made as the Core element in every place. Computerization has become an essential one, for the people who prefer speedy and ease of access. Human beings are liable to make mistakes and the Output usually depends upon the efficiency of the persons involved. But computers could usually generate error output and highly efficient which varies depending on the person operating.

SYSTEM STUDY AND ANALYSIS

2. SYSTEM STUDY AND ANALYSIS Systems analysis is the study of sets of interacting entities, including computer systems analysis. This field is closely related to requirements analysis or operations research. It is also "an explicit formal inquiry carried out to help someone (referred to as the decision maker) identify a better course of action and make a better decision than he might otherwise have made." When a computer-based information system is developed, systems analysis (according to the Waterfall model) would constitute the following steps:
The development of a feasibility study, involving determining whether a project is economically, socially, technologically and organizationally feasible.
Conducting fact-finding measures, designed to ascertain the requirements of the system's end-users. These typically span interviews, questionnaires, or visual observations of work on the existing system.
Gauging how the end-users would operate the system (in terms of general experience in using computer hardware or software), what the system would be used for and so on
Another view outlines a phased approach to the process. This approach breaks systems analysis into 5 phases:
Scope Definition
Problem analysis
Requirements analysis
Logical design
Decision analysis
Use cases are a widely-used systems analysis modeling tool for identifying and expressing the functional requirements of a system. Each use case is a business scenario or event for which the system must provide a defined response. Use cases evolved out of object-oriented analysis; however, their use as a modeling tool has become common in many other methodologies for system analysis and design.

EXISTING SYSTEM
10
2.1 EXISTING SYSTEM The existing system is handled manually. The system has a formatted accounting system for Purchase and Sales. The indent is prepared when items are to be purchased And bill is generated for sale of items. The system follows the predetermined purchase and sales procedures. Drawbacks of existing system
Manual systems are more time consuming
Large number of ledger books has to be maintained for each transaction
Since the data are entered manually there are possibilities for errors.
Data security is very minimal.
There is a possibility for double entries.
Since the transaction are mainly viz. paperwork updating of data is very hard.
Generating the reports in the desired format is a tedious process.
Reporting to the higher officials is not done through the proper channel.
Data stored on papers is subject to loss due to physical damage.

ABOUT VISUAL BASIC
14
2.3 ABOUT VISUAL BASIC In 1975, the only 20-year-old Bill Gates and his good friend, Paul Allen develop Basic on the microprocessor. And then Basic became popular to computer players. Basic has become the first program language for many people since the personal computers became more and more popular. Along with the evolution of the computer technique, the pure writing output was replaced by graphically operational interface. The Microsoft Company announced Visual Basic1.0 in 1991. Much software likes to add a word “Visual” in front of their names, and Visual Basic is the pioneer among them. Why do we say “visual” to describe Basic. Because Visual Basic provides programmers many visual tools to design windows. These windows will be as same as the appearances when the programs are executing. The Integrated Development Environment The Visual Basic Integrated Development Environment (IDE) may be the single biggest reason for the vast popularity of Visual Basic. It provides everything you need to develop applications in an easy-to-use-and-learn Graphical User Interface (GUI) like many Windows applications; Visual Basic has several ways in which it can be opened. First, and probably the easiest way to access Visual Basic is through the Windows Start menu – the exact path required to access this shortcut is dependent upon your installation and may differ on individual machines. Another option is to create a shortcut on your desktop, which will execute Visual Basic by double-clicking on it. Lastly, because Visual Basic sets up default associations when it is installed, you can also run it by double-clicking on files that end with a VBP (Visual Basic Project) extension. Pointer: The pointer is the only item on the Toolbox that isn’t a Control. You can use it to select Controls that have already been placed on a Form. Picture Box: You use the Picture Box Control to display images in several different graphics formats such as BMP, GIF, and JPEG among others. Label: The Label Control is used to display text information that does not have a need to be edited by an end user. It’s often displayed next to additional Controls such as text boxes to label their use. Text Box: You use Text Box Controls for user input. It may be the most widely used Control.
15
Frame: A Frame Control is typically used for containing other Controls and for dividing the GUI. Controls placed within a Frame cannot be displayed outside of it, and if the Frame is moved on the Form, the Controls are moved with it. Command Button: Much like the Text Box Control, Command Button Controls are used for input on almost every Form. They are used as standard buttons for input like OK or Cancel. Check Box: If you need the ability to select True/False or Yes/No, the Check Box Control is the correct Control. Option Button: The Option Button Control is similar to the Check Box Control in that it offers the ability to select an option. However, an Option Button Control is most often used when a group of options exists and only one item can be selected. All additional items are deselected when a choice is made. List Box: The List Box Control contains a list of items, allowing an end user to select one or more items. Combo Box: Combo Box Controls are similar to List Box Controls, but they only provide support for a single selection. Scroll Bars: The HScrollBar and VScrollBar Controls let you create scroll bars but are used infrequently because many Controls provide the ability to display their own Scroll Bars. Timer: The Timer Control is an oddity when it is compared to other Controls, in that it isn’t displayed at runtime. It’s used to provide timed functions for certain events. Drive List Box, Dir List Box, and File List Box: These Controls can be used individually, but many times are used together to provide dialog boxes (also known as Windows in this book) that display the contents of Drives, Directories, and Files. Shape, Line: The Shape and Line Controls are simply used to display lines, rectangles, circles and ovals on forms. Image: You can think of the Image Control as a lighter version of the Picture Box Control, and although it doesn’t provide all of the functionality that the Picture Box Control does, it consumes fewer resources. As a result, you should use the Image Control whenever possible. Data: The Data Control is a component that allows you to connect one or more Controls on a form to fields in a database.

ABOUT MS-ACCESS
17
2.4 ABOUT MS-ACCESS Microsoft Access, also known as Microsoft Office Access, is a database management system from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. It is a member of the Microsoft Office suite of applications, included in the Professional and higher editions or sold separately. On May 12, 2010, the current version of Microsoft Access 2010 was released by Microsoft in Office 2010; Microsoft Office Access 2007 was the prior version. Microsoft Access stores data in its own format based on the Access Jet Database Engine. It can also import or link directly to data stored in other applications and databases. Software developers and data architects can use Microsoft Access to develop application software, and "power users" can use it to build software applications. Like other Office applications, Access is supported by Visual Basic for Applications, an object-oriented programming language that can reference a variety of objects including DAO (Data Access Objects), ActiveX Data Objects, and many other ActiveX components. Visual objects used in forms and reports expose their methods and properties in the VBA programming environment, and VBA code modules may declare and call Windows operating-system functions.

SYSTEM DESIGN
22
3. SYSTEM DESIGN DATABASE: A database is an application that manages data and allows fast storage and retrieval of that data. DATABASE MANAGEMENT SYSTEM: A database management system (DBMS) is a software package designed to define, manipulate, retrieve and manage data in a database. A DBMS generally manipulates the data itself, the data format, field names, record structure and file structure. It also defines rules to validate and manipulate this data. DATA INDEPENDENCE: The ability to modify a scheme definition in one level without affecting a scheme definition in a higher level is called data independence. LOGICAL DATA INDEPENDENCE: The ability to modify the physical scheme without causing application programs to be rewritten PHYSICAL DATA INDEPENDENCE: The ability to modify the conceptual scheme without causing application programs to be rewritten NORMALIZATION: Database normalization is the process of organizing the fields and tables of a relational database to minimize redundancy and dependency. FIRST NORMAL FORM (1NF): is a property of a relation in a relational database. A relation is in first normal form if the domain of each attribute contains only atomic values, and the value of each attribute contains only a single value from that domain. SECOND NORMAL FORM (2NF): A table that is in first normal form (1NF) must meet additional criteria if it is to qualify for second normal form. Specifically: a table is in 2NF if and only if it is in 1NF and no non-prime attribute is dependent on any proper subset of any candidate key of the table. A non-prime attribute of a table is an attribute that is not a part of any candidate key of the table. THIRD NORMAL FORM (3NF): Cod’s definition states that a table is in 3NF if and only if both of the following conditions hold:
The relation R (table) is in second normal form (2NF)
Every non-prime attribute of R is non-transitively dependent (i.e. directly dependent) on every superkey of R.
23
BOYCE CODD NORMAL FORM: A relational schema R is in Boyce–Codd normal form if and only if for every one of its dependencies X → Y, at least one of the following conditions holds
X → Y is a trivial functional dependency (Y ⊆ X)
X is a superkey for schema R

DATA FLOW DIAGRAM
25
3.1 DATA FLOW DIAGRAM A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system, modeling its process aspects. Often they are a preliminary step used to create an overview of the system which can later be elaborated. DFDs can also be used for the visualization of data processing (structured design). A DFD shows what kinds of information will be input to and output from the system, where the data will come from and go to, and where the data will be stored. It does not show information about the timing of processes, or information about whether processes will operate in sequence or in parallel (which is shown on a flowchart).
