記帳系統從需求到實現 ----數據庫的設計

需求跟UI原型設計完成以後，現在就開始對數據庫進行設計和實施了，我用的是Powerdesigner做的數據庫模型圖，然後自動轉化成MySql的腳本代碼。模型圖如下：

數據模型圖

 

由於表內已經有了描述，所以數據字典我也不寫了，大家看看描述就大概知道了。

 

drop table if exists TAccount;

 

drop table if exists TAccountEvent;

 

drop table if exists TAccountType;

 

drop table if exists TConsumeType;

 

drop table if exists TEvent;

 

drop table if exists TFriendRelation;

 

drop table if exists TGroup;

 

drop table if exists TLeaveword;

 

drop table if exists TLovenote;

 

drop table if exists TUser;

 

drop table if exists TUserConsumeType;

 

drop table if exists TUserGroup;

這裏把前面的腳本代碼copy過來運行，數據庫便生成好了。
