BBS 系统开发与账户安全保护的实现
摘 要
BBS 的英文名称是 Bulletin Board System,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 ASP 和 SQL
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
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。

Development of BBS System and Implementation of Account
Security Protection
Abstract
BBS’s English name is Bulletin Board System. In 90's of the last century BBS
enters China and becomes popular. Aim of this design is to develop a simple system
of BBS based on Asp and SQL, and the implementation of account Security
Protection. Furthermore, BBS system is good for easy operation and friendly interface,
it has comprehensive application foreground. Development of BBS System mainly
narrates basic function and method for System Design. Then take this system as an
example, recommend developing the step of this system one by one: system analysis,
system design, and system realization. Successively used the data stream chart the
system function structure drawing in the system analysis to analyze each kind of data
which the BBS system needed. In the design of the system, detailed each function
module which has represented the system, necessary database form and field, design
of the menu, and implementation of user's account security protection by using MD5
function. In the realization of the system, I got anticipated achievement, realized each
module’s basic function, and showed the modules realization core code and the main
GUI design.
Key words: BBS system;ASP;SQL;Account security
