结构设计过程

• Many former systems like this is purely according to c / s mode , but this system is base on the combine of c / s and b / s , and the same time , the high speed network technique of today is used , therefore the function of this system is more perfect ; the constructions of each departments of this system about database are discussed ( include mold construction , the table construction of database etc . ) , the key techniques of database ( stored process , trigger and the safety technique ) , the safety design of database , the safety design of program etc . , and the establishing of data warehouse of customer is introduced , and a technique about graph of customer data warehouse ( realized with powerbuilder ) ; the design of network construction is briefly discussed ; the choice of servers is introduced in detail ( include the database server and the the web server )
  以往的此类系统大多单纯基于c / s模式设计，而本系统是两种模式的结合，充分利用当今高速发展的网络技术，所以功能更加完善和强大；数据库技术方面详细介绍了各分系统的功能模块设计（包括模块结构、数据库表结构设计等） 、后台数据库的关键技术（存储过程、触发器和数据库的安全技术） 、数据库安全性设计（采用双机容错解决方案） 、程序安全性设计和权限配置等，同时介绍了客户数据仓库的建立方案和客户数据仓库的一种可视化技术（用pb和sybase的工具来实现） ；简要介绍了系统的网络结构设计过程；详细介绍了服务器的选择和选择结果（包括数据库服务器和web服务器） 。
