ph2_studmanage's Introduction
This is the StudManagement Project for Ph2 in KR. As for more details, you can see the documents. And giving thanks to Robert Pickering's blog http://strangelights.com/blog/archive/2013/05/20/using-the-android-gridview-as-a-datagrid.aspx ///////////////////////////////////////////////////////////////// 学校管理系统是在KR学习期间,为巩固第二阶段所学知识,由授课教师提出,学生需按既定时间完成的项目。 该系统是对第一阶段二叉树版学生管理系统的升级,采用数据库进行数据的管理。为减少各模块间的耦合,采用三层结构进行设计。 定义 DataBase <---> Server <---> M Server <---> Client 其中, DataBase: 相关数据存储,这里一般指SQL Server Server : 与DataBase交互,操控数据处理,回传数据给M Server M Server : 逻辑层,根据传入的UI数据,构造相关SQL 语句,传给Server, 也可进行数据安全性处理。 Client : Window或者Android客户端 目标 结合数据库,实现网络版的学校信息管理系统,包括: 1)对学生、老师、课程、班级的管理 正确梳理数据关系,建立相关数据库 2)分层设计,各司其职,减小修改所带来的影响 SQL Server <-----> Server <----> M Server (Logic) <---->Client (UI) 3)利用本地缓存,实现高效的查询效果 借助修改时间,两次修改之间的查询数据进行本地缓存。 4)利用连接池,重用数据库连接,处理Server向SQL Server频繁的、短时的操作 5)利用线程池,实现Server与多M Server, M Server 与 多Client间的交互。 6)同时提供PC客户端和Android客户端,方便用户使用
