【开源系列】三国演义LBS （九）源码：持久层

前言：

-----------------------------------------------

相关讨论组入口： http://www.pixysoft.net/ (点击进入)

功能简介：

-----------------------------------------------    

1. 支持SQLite，Access，MySQL，SqlServer，Oracle的操作。

2. 支持同时对多个数据库操作，并相互交互。

3. 支持表转简单的对象，进行简易ORM操作。

4. 是缓存、orm等后期模块基础。

下期预告：

-----------------------------------------------     

Pixysoft.Framework.Noebe.Orm 纯ORM操作，使用自主研制的AOP框架，性能与非ORM操作一致！！！

什么叫做完美？这个就是完美。
