1、JSP+SQL-BBS论坛系统的设计与实现(BBS的英文名称是BulletinBoardSystem,翻译为中文就是“电子公告板”。BBS在上世纪九十年代进入中国,并迅速普及。本设计的目的是用JSP和SQLServer2000开发一个简易的BBS系统,并实现账户安全保护。此外,BBS系统有操作简单、界面友好的特点,并具有广泛的应用前景。BBS系统开发主要讲述了系统设计的基本功能和方法。接着以BBS系统为例,逐一介绍开发的步骤:系统分析、系统设计、系统实现。在系统分析中先后用数据流程图、系统的功能结构图分析了BBS系统所需的各种数据。在BBS系统的设计中,详细的展现了系统的各个
2、功能模块,所需的数据库表及表字段,菜单的设计等,并通过运用MD5函数,实现用户账户的安全保护。在BBS系统的实现中,取得了系统预期的成果,基本使各个模块的功能得以实现,并给出了模块实现的核心代码和主要的界面设计。关键词:BBS系统,JSP,SQLServer2000,Accountsecurity ABSTRACTBBS’sEnglishnameisBulletinBoardSystem.In90'softhelastcenturyBBSentersChinaandbecomespopular.Aimofthisdesignistodevelopasimplesystemof
