1.4 INTRODUCTION TO VB 6.0 Visual Basic was designed to be easily learned and used by beginner programmers. The language not only allows programmers to create simple GUIapplications, but can also develop complex

applications.

Programming

in

VB

is

a

combination

of

visually

arranging components or controls on a form, specifying attributes and actions of those components, and writing additional lines of code for more functionality. Since default attributes and actions are defined for the components, a simple program can be created without the programmer having to write many lines of code. Performance problems were experienced by earlier versions, but with faster computers and native code compilation this has become less of an issue.

1.5 MS Access Microsoft Access uses similar features to those found in other databases and some other features that are unique. Most of these additional features are made possible by Access’s tight integration with the Windows NT operating system. MS Access contains the data storage options and the capability to store and process the same volume of data as a mainframe or a mini computer. MS Access is the latest Client/Server based RDBMS package from Microsoft. Its new features provide a very high degree of performance making it comprehensive package for database management. It is a largely used in medium-sized establishments.

Analysis: Electronic Store management system becoming an essential to efficiently manage inventories in computer age. Electronic Shop Management System is a workable application for retail store inventory and accounts management. It keeps a list STOCKS and products at a store and can do operations on them. The most important operation is a "PURCHASE", all the transactions and billing details and stock purchasing details involved on it. Why We Want to Hold Inventories •

Improve customer service

•

Reduce certain costs such as

•

Ordering costs

•

Stock out costs

•

Acquisition costs

•

Start-up quality costs

•

Contribute to the efficient and effective operation of the production system

2.1 INTRODUCTION The software project is initiated by the client needs. In the beginning, these needs are in the minds of various people in the client organization. The requirement analyst has to identify the requirements by talking to these people and understanding their needs. For such systems, the requirements problem is complicated by the fact that the needs and requirements of the system many not to be known even to the user-they have to be visualized and created. Hence, identifying requirements necessarily involves specifying what some people have in their minds. When inputs from multiple people are to be gathered, as is often the case, these inputs are likely to be inconsistent as well.

2.1.1 Purpose: This project is aimed at providing an economically feasible security and communication system that will provide very good features that can fulfill the security needs of a small organization. The project will be supposed to implement the storage of products so that a large collection could be maintained with minimum storage space. This project will also be able to provide reports of products sold to the customer and brought to the store.

2.1.2 Scope: The project could be implemented in an average sized organization. An average company will not be very keen on spending loads of money on ledgers. Where as our project will greatly reduce the costs which is using common and cheap office items like database and desktop application. And also there is no requirement to store books or accounts. The data is directly stored in the database in the hard disk of the PC.

2.1.5 Overview Electronic Shop is a process of storing the products which is capable of maintaining storage of large amount of products. The primary purpose of this application is to implement the above stated functionality. The application should be capable enough to store the products and also perform some updating on the products that is stored. It will be having user friendly GUIs that will guide the user to easily achieve the same. The application shall also have some features like reports displaying in the same window. In addition to this the application also supports feature to search products. It can also search products based on criteria so that the employees will be able to view the same. The application is to be fully developed under vb platform using Visual Basic 6.0

2.2 OVERALL DESCRIPTION

2.2.1 Product Perspective The product will be developed completely independent and standalone. Each user will have to have an individual copy of the product.

2.2.3 User Characteristics The user of this product is supposed to be fairly educated about the usage of the computers. He should understand how to store products and he should have knowledge about various products so that they could be saved. A person who has no knowledge of computers will find it difficult to understand the system. But with a little knowledge it will be very easy to handle the project.

2.2.4 General Constraints Designed to run on Windows 98 and further versions.

3.1 INTRODUCTION The purpose of the Design Phase is to a solution of the problem specified in the requirements document. This is the first step in moving from the problem domain to the solution domain. The design of a system is perhaps the most critical factor affecting the quality of the software; it has a major impact on the later phases is the Design Document. This Document is similar to a blueprint or a plan for the solution and is used later during implementation, testing and maintenance. The Design activity is often divided into separate phases – System Design and Detailed Design. System Design is sometimes also called Top-Level Design. This system design aims to identify and modules that should be in the system, the specifications of these modules, and how they interact with each other to produce the desired result. At the end of the System Design all the major data structures, file formats, and the major modules in the system and their specifications are decided.

3.2 APPLICABLE DOCUMENTS The document used for preparing system design is software requirement specification (SRS) for Inventory Management System.

3.4 DESCRIPTION OF PROGRAMS 3.4.1 Context Flow Diagram (CFD)

A Context Flow Diagram is a top level (also known as level 0) data flow diagram. It only contains one process node (process 0) that generalizes the function of the entire system in relationship to external entities. In context diagram the entire system is treated as a single process and all its inputs, outputs, sinks and sources are identified and shown.

NOTATIONS USED IN FLOW DIAGRAM:

Bubble  The Bubble represents a process or transformation that is applied to the data which changes in some way. Each bubble is assigned a number. Box  The Box is called an entity which represents a producer or a customer of the Information Arrow  The Arrow represents the data flow. All arrows in the data flow diagram are labeled. The arrowhead indicates the direction of data flow. Parallel Lines  Represents a repository of data that is to be stored for use by one or more processes.

3.4.2 Data Flow Diagram (DFD):

A Data Flow Diagram (DFD) is a graphical representation of the "flow" of data through an Information System. A data flow diagram can also be used for the visualization of Data Processing. It is common practice for a designer to draw a context-level DFD first which shows the interaction between the system and outside entities. This context-level DFD is then "exploded" to show more detail of the system being modeled.

A DFD represents flow of data through a system. Data flow diagrams are commonly used during problem analysis. It views a system as a function that transforms the input into desired output. A DFD shows movement of data through the different transformations or processes in the system.

Dataflow diagrams can be used to provide the end user with a physical idea of where the data they input ultimately has an effect upon the structure of the whole system from order to dispatch to restock how any system is developed can be determined through a dataflow diagram. The appropriate register saved in database and maintained by appropriate authorities.
