C#开发的WEB开发的简单框架 节省开发信息管理系统时间 提高开发效率

构建一个WEB开发的基础框架（主要包括数据库处理、页面框架及工具类），形成ASP.NET信息管理系统快速开发架构。
一、框架实现了基于XML定制的列表查询及图表展现
二、列表实现了复杂查询条件、合并行列(分组求和的处理)、汇总行及钻取数据和图表的钻取
三、编辑配置支持单表数据的增加和修改，针对开发人员实现的编辑页面可方便扩展主表新增字段
使开发人员专注于系统的业务实现，节省开发时间，提高开发效率

您看到的研发管理平台我只用了一个月的时间（还只是正常工作8小时以外的时间）做出来的。
所以自己觉得自己之前开发的用XML配置实现界面的开发架构，可以使开发人员专注于业务实现，提高信息管理系统开发效率
