DataAccessor是一个轻量级的数据访问组件，通过DataAccessor您可以方便的拥有如下特性： 1.支持通过事务执行多条SQL语句，而不需要在SQL语句中编写事务处理代码； 2.支持异步操作数据库； 3.支持单连接模式操作数据库，对于MSAccess等不支持连接池的数据库系统能够大幅降低因为反复打开或关闭数据库连接耗费的时间，提高访问数据库效率； 4.支持通过配置文件切换不同的DBMS，例如：SqlServer、Oracle或者MSAccess，对于需支持多DBMS的系统，再也不需要写N个数据访问层的实现； 5.支持扩展，您可以很方便的扩展DataAccess以支持更多的DBMS； 6.支持把Sql语句通过xml文件配置到代码外并且不用改变dbms的SQL语句的写法，修改sql语句再也不需要重新编译源代码； 7.轻量级，仅一个DLL即可支持上述所有特性……

ADO .Net DataSource Library. Allows simple creation of ADO .Net Database projects by automating the process from creating the ADO Connection object to creating the dataadapter and auto generating all insert/update statements and thus providing a databinding source by which to bind controls to at the end of the process. Example: CDataSource DataSource = new (ConnectionString, DBType); DataSource.AddTable(TableName,QueryName,SQL,AutoGen, AltAutoGen); Datagrid.DataSource = DataSource.GetBindingSource(QueryName); This means fewer lines of code are required to get a functioning binding source up and running. The library supports SQLServer, OLE and ODBC Providers. Oracle .Net Provider can be built into this library if needed in future versions.

This .Net class library is designed to integrate into enterprise applications to help support their high performance and reliability requirements. The focus of the Enterprise Library is to provide simple and robust mechanisms that take full advantage of the amazing capabilities already in the .Net Framework and extend those capabilities to support the needs of enterprise applications. The first major component of the library is the Operations Framework. The Operations Framework provides flexible and efficient support for asynchronous operations that can fully utilize the power of computers with multiple processors and make I/O operations much faster.

Extremely simple yet powerful ORM that extends DbConnection and DbTransaction. With IvyORM boilerplate code is reduced while keeping SQL a first class citizen.

Linquify is a Visual Studio 2008/2010 Addin and C# .NET business class / DTO generator for LINQ to SQL and the Entity Framework. It supports rapid development of .NET and ASP .NET web application data layers allowing you to query as: Person.Load(5); Person.Name="n"; Person.Save()
