（极力推荐）家教信息管理平台（含源码和数据库）
应用背景与功能目前，中小学生的学习负担均较重。新知识多，作业量大。对于孩子来说，难免有一些消化不了的东西。在此情况下，如不能及时地把所欠缺的知识补起来，势必造成恶性循环，不理解的东西越压越多。家教可以有针对性地单独授课，学生学习的效果较好，越来越多的家长给孩子选择了请家教。为了找到合适的家教，出现了很多的家教中介，但信息的共享方面还是互联网更强，于是越来越多的家教网站产生了。必备知识注意：如果你是首次接触ASP.NET 2.0，那么请先阅读本书第3章关于ASP.NET 2.0新特性的内容，否则你可能会感觉像在云里雾里。学习过ASP.NET 2.0
