1、摘要I招投标管理系统的设计与实现(预览摘 要招投标管理系统的发展在国内日趋成熟,应用也逐渐普遍起来,已经成为企 业招投标过程中不可缺少的工具。这种信息管理模式使招投标业务管理更加标准 化、规范化 , 将业务人员从繁重的手工操作中解放出来 , 降低招投标成本,实现招标 投标的网络式管理,而且随着全球经济与网络的逐步发展,企业对投招标的需求 量也会与日俱增。为了满足庞大的市场需求,结合当下系统开发所采用的技术,开发一个基于 网络的招投标管理系统是十分必要的。本系统解决了竞价前后供货商的批准和最 终确认流程,以及对网上竞价的历史信息备份,并且可以随时随地的调档查询以 往的历史竞价信息,对采购部门的招
2、标流程进行了规范化,最大限度的提高企业 的综合效益。在课题的研究过程中,重点分析了系统对所需软硬件的详细需求,具体的描 述了招投标信息系统的分析、设计、和实现过程。并结合公司对招投标项目对规 范化、透明化和规范化的要求,完成对整个系统的总体设计。系统采用了三层 B/S体系结构,并进一步完善详细设计和对数据库的实现,其中主要分析了招标投标 环节中各个功能模块之间的关系 , 并且介绍招投标管理系统的整个设计过程。接着 本文对系统中的数据库的模型设计进行了详细说明,包括实体联系图和数据表结 构。本系统在设计思想上采用面向对象机制,将项目、产品、厂商等封装成数据 类,并且每个类都有对应的操作类;数据库
3、连接上采用了连接池,以此来提高数 据库效率; 技术上采用 JSP+JavaBean和 SQL Server 2000来实现。 最后对系统进行 编码及功能进行了测试,对系统中用到的关键技术 JavaBean 及各个模块之间所涉 及到的关键代码进行了详细的研究分析,最终实现基于网络的招投标管理系统。 招投标管理系统的实现为企业的招投标管理工作提供了更加高效便捷的途 径,对于未来企业的信息化建设更是具有不可替代的应用价值和现实意义。关键词:招投标管理系统,信息查询 ,JSP,JavaBean摘要 IIIABSTRACTBidding ma is gradually developed , and i
