.NET的ORM框架 EntityFramework 介绍

     <p>EntityFramework 是微软公司为 .NET 开发人员推出的一个 ORM 框架，来实现对数据库单表数据的创建、读取、更新和删除操作，也就是所谓的CRUD（C:Create/R:Read/U:Update /D:Delete）。需要说明的是，如果在VS2008中使用EntityFramework就需要安装VS2008SP1。</p>    <ul>     <li class="unordered">Applications can work in terms of a more application-centric conceptual model, including types with inheritance, complex members, and relationships.<br /> </li>     <li class="unordered">Applications are freed from hard-coded dependencies on a particular data engine or storage schema.<br /> </li>     <li class="unordered">Mappings between the conceptual model and the storage-specific schema can change without changing the application code.<br /> </li>     <li class="unordered">Developers can work with a consistent application object model that can be mapped to various storage schemas, possibly implemented in different database management systems.<br /> </li>     <li class="unordered">Multiple conceptual models can be mapped to a single storage schema.<br /> </li>     <li class="unordered">Language-integrated query (LINQ) support provides compile-time syntax validation for queries against a conceptual model. </li>    </ul>    <p><img style="width:686px;height:464px;" alt=".NET的ORM框架 EntityFramework 介绍" src="https://simg.open-open.com/show/a4ad3206b1a1d0c01f98d08fc50d876c.jpg" /><br /> <br /> </p>    <p><strong>项目主页：</strong><a href="http://www.open-open.com/lib/view/home/1328450048109" target="_blank">http://www.open-open.com/lib/view/home/1328450048109</a></p>
