Super Market also generates various types of reports in order to keep all the activities under proper control. The software package Automation of Super Market can be said to be a benchmark for betterment of the service in Super Market as it takes care of the system administration. The system has been developed in such a way that the user will find them absolutely essential in generating details of the market. Programming language- Java Development Kit 1.4.0(JDK1.4.0), RDBMS backend- SQL server 7.0, ernet Technology- HTML, Java Server Pages (JSP), Web server- Java Web Server 2.0 (JWS 2.0) and TOMCAT are used to develop the software package Automation of Super Market Keywords: DFD, ER-Diagram, Database, JSP, HTML, Reports I. INTRODUCTION Super Market is a shopping center engaged in purchasing consumer goods from solo vendor and manufactures and selling to customers and retailers. Before the proceeding of Super Market was handled manually, but this method has to face a lot of difficulties of problems when the super market started to deal with a large volume of transaction and data. Some of the common problems are illustrated as under: (i) The storage and preservation of large volume of data becomes difficult. (ii) The recording of the data on manual system is very costly because the writing and reading process is very low. (iii) There are always good chances of errors. (iv) A manual system does not help to provide quick view of stock available, invoices, payments etc. After knowing the various limitations of manual system, the super market realized that the computerization methods, as it provided them the following advantages: The storage and preservation of large volume of data becomes very simple and easy. The recording process on a computerized system is very cheap. The reading process of data is very fast and easily readable on machine. There negligible chances of errors in a computerized system. The computerized system helps to provide a quick view of all the details of a super market. II.

2 Programming language- Java Development Kit (JDK1.4.0) RDBMS backend- SQL server 7.0 SQL Server 7.0 ernet Technology- HTML, Java Server Pages (JSP), Web server- Java Web Server 2.0 (JWS 2.0),TOMCAT Microsoft SQL Server 7.0 is one of the powerful, high performances, preferred Relational Database Management System. It is capable of supporting hundreds of simultaneous users, depending on application and the hardware environment. It is designed as a central repository for all the data of the organization and to meet the demanding requirements of distributed client/server computing. JAVA Since there are problems in C & C++ compilers that the compilers are expensive and time consuming to create, so an easier and more cost-efficient solution was needed. JAVA is a portable, platform-independent language that could be used to produce code that would run on a variety of CPU s under differing environments. JSP (Java Server Pages) Anything you can do with PHP, you can do with JSP; the reverse is not true. JSP is much more powerful, since it has access to all the Java libraries. PHP only has access to PHP libraries. JSP technology is created to support authoring of HTML and XML pages. It makes it easier to combine fixed or static template data with dynamic content. Apache Tomcat Web Server Tomcat is an open source product maintained by the Jakarta Project of the Apache Software Foundation. Tomcat replaces the old Java Servlet Development Kit (JSDK) that was previously provided by sun. It contains the class libraries, documentation, and run-time support that need to create and test jsp. III. SYSTEM DESIGN System Design is the first step in the development phase for any engineered product of system. System design is an activity concerned with making major decisions, often of a structural nature. It shares with programming a concern for abstraction information representation and processing sequences, but the level of details is quite different at the extremes. Design builds coherent, well-planned representation of programs that concentrate on the interrelationship of parts at the higher level and the logical operations involved at the lower levels. Software design is a process through which requirement are translated into a representation of the software. The system design is carried out in two phases. Preliminary Design Detailed design A. Preliminary Design This design aims to identify the modules that should be in the system, the specification of these modules and how they interact with each other to produce the desire results. At the end of preliminary design all major data structures, files formats, output formats, and major modules in the system and their specifications are decided. The tools that assist in Preliminary design process are Data Flow Diagrams (DFDs) and Entity- Relationship Diagram (ER-Diagram). Data Flow Diagram (DFD): Data Flow Diagram (DFD) depicts information flow, the transformation flow and the transforms that are applied as data move from input to output.. DFD of Automation of super market is given on Figure-1. Entity-Relationship (ER) Diagram: ER-Diagram is a primary tool, which helps in Database Design. The overall logical structure of a database can be expressed graphically by ER-Diagrams. ER diagram of Automation of super market is given on Figure-2. B. Detailed Design Input Design: Input design is the process of converting useroriented inputs to a computer-based format. The goal of designing input data is to make data entry easy, logical and free from errors. The data is fed into the system using simple interactive forms. The forms have been supplied with message so that the user can enter data without facing any difficulty. The data is validated during data entry and if any errors are found then appropriate error message and displayed. This ensures that only correct data is stored in the database. Sample Screen inputs are shown in Figure-3 53

3 Based on the proposed system, the database design was finalized. The main part of the database design is creation of tables and defining their relations. Figure 1. DFD of automation of Super Market Output Design: The objective of the output design is to convey the information of all that past activities, current status and to emphasize important events. The output generally refers to the results and information that is generated from the system. The output design of the system was accomplished keeping in mind the following objectives. Determine what information to display. Arrange the presentation of information in an acceptable format. Decide how to distribute the output to the intended recipients. Sample Screen outputs are shown in Figure-4. Database Design: Database Design is a process of organizing data pertaining to concerned organization in an orderly manner to provide easy access to the required information. ER-Diagrams and Normalization procedure are used in Database design. Figure 2. ER-Diagram of Super Market The tables for the SUPER database are in the normalization form. The data structure as follows. Data Structures Table: CUSTMAST Description: Details about the Customer Primary Key: Custcode 54

7 V. VALIDATION CHECK, IMPLEMENTATION AND MAINTENANCE, TESTING, SYSTEM SECURITY MEASURES Validation check Validation succeeds when software functions in a manner that can be reasonably expected by the customer. This system use a process called alpha and beta testing to uncover errors that only the end-user seems able to find. Implementation and maintenance There are three aspects of Implementation, they are: Users Training: The users are given training about, computer hard wares, software and languages. Conversion: Conversion is the process of converting the old system into a new one as we are changing the present manual system into the newly computerized system. Post Implementation: The post implementation review will be conducted later after the complete implementation of the system at the client side. Software Maintenance traditionally denotes the process of modifying a software product after it has been delivered to the customer. Testing The Testing techniques applied to this software are White box Testing White box testing is a test case design method that uses the control structure of the procedural design to derive test cases. Black box Testing Black box testing focuses functional requirements of the software. It derives sets of input conditions that will fully exercise all requirements of a program. System Security Measures Security of data is of paramount importance. It is an irreplaceable asset and it is vital in enterprise application. During online processing of data various security functions should be enforced at different levels. The online system uses to client-server database in which discretionary security mechanism and mandatory security mechanism is effectively implemented. The discretionary access control is based on the granting and revolving of privileges. The mandatory access control is especially used to maintain multilevel security. VI. CONCLUSION At the end of this project, we hope that, the system will provide a full proof Automation of a Super Market. I expect that, the system will fulfill all the requirements, inquiries of any Super Market even if they are very small or large number of transaction occurs. So as per my knowledge the procedure and methodology will satisfy all the needs/requirements. So it can be properly implemented to the best of expectation and strategies. In future we can use it in ernet also. We can make another nice project without creating a new project. VII.
