ABSTRACT With economic development, social progress, the puter and went to work learning and our daily lives, we bee an indispensable tool in everyday life. As science and technology continue to improve, puter science increasingly mature, and its powerful functions for the people to deeply understand that it has entered human society in various fields and is playing an increasingly important role. It has to go down to the daily work and life, such as word processing, information management, aided design, graphics and video processing, as well as education and training game entertainment. All people without special training will be able to use puters to plete numerous plex. However, although now the world has been filled with an overabundance of software, but they still can not meet the special needs of the various users, it also had to develop software suited to their particular needs. Professional Windows application software development before the work is needed in many professional knowledge and petence through special training. Different now, even if you have not received strict procedures designed training, the use of JAVA also like to develop a powerful, and suited to their special needs applications. supermarket management system using puter management Supermarket stocks a puter application and management of technology innovation in the puter before the inventory management are not yet universal manual written by the staff to operate. Supermarkets are now generally used puter intelligent management, using the puter as a tool for puter supermarket inventory management procedures to help managers more effectively supermarket inventory management. Supermarket Jinxiaocun management system is a typical management information system (MIS), including its main development background to the establishment and maintenance of the database and frontend application. The request for the establishment of strong data consistency and integrity, good for the security of the data. For the latter request applications functions, such as easy to use features. Database adoption SQL Server 2021, request because of our system, adopt it to can suit our work need pletely, and it a data for supporting type is abundant very, support simple, the expenses is lower. keyword : supermarket management,JAVA, database, Microsoft SQL Server 2021 目 錄 第一章 超市 管理系統(tǒng)問題定義 ............................................... 1 課題背景 .............................................................. 1 研究意義 .............................................................. 1 國內(nèi)外發(fā)展概況 ........................................................ 2 第二章 可行性分析 ........................................................ 3 經(jīng)濟(jì)可行性 ............................................................ 3 技術(shù)可行性 ............................................................ 3 操作可行性 ............................................................ 3 第三章 需求分析 .......................................................... 4 背景分析 .............................................................. 4 功能分析 .............................................................. 5 性能分析 .............................................................. 5 運(yùn)行環(huán)境 .............................................................. 5 第四章 總體設(shè)計(jì) .......................................................... 6 系統(tǒng)設(shè)計(jì)原理 .......................................................... 6 功能模塊設(shè)計(jì) .......................................................... 6 第五章 數(shù)據(jù)庫設(shè)計(jì) ........................................................ 9 數(shù)據(jù)庫設(shè)計(jì)規(guī)則 ........................................................ 9 數(shù)據(jù)庫概念結(jié)構(gòu)設(shè)計(jì) .................................................... 9 數(shù)據(jù)庫關(guān)系模型設(shè)計(jì) ................................................... 12 數(shù) 據(jù)庫邏輯結(jié)構(gòu)設(shè)計(jì) ................................................... 12 第六章 詳細(xì)設(shè)計(jì) ....................................................
