The current information system has complex structure, large scale and need to access more than one data type. Faced on the situation of simultaneously accessing to multiple type databases and other data sources, a kind of heterogeneous data access is designed based on. NET which can dynamically access to actual need database when the system is running, and presents the uniformed interface for different types of database manipulation. The design thoughts of component are introduced, detailed description realization methods and functions and the relative configuration specification for use and the situation that the component application to actual system are given, and advices and ideas for the component improvement are given as well. The component can also be integrated into the data access layer, and greatly improve the development efficiency, reduce the cost of development and maintenance when needs to construct information system.
