The main research of the thesis is the implementation of batch data interchange function based on ETL. UDI has two main characteristics. First, by the separation of source systems and target systems, the platform provides data exchange among the systems to avoid point to point communication. Second, the data process of source systems is consolidated by platform based on the systems common requirements. The data extraction is implementated from the simple data exchange to the more complicated view of business logic.

平台的最大特点体现在，一是在源系统和目标系统之间实现了批量数据交换，避免多个系统之间批量数据交换时的点点沟通，在源系统和目标系统之间进行隔离；二是将源系统数据加工处理时的共性需求，集中于平台内部统一实现，这一共性需求的统一处理，从简单的数据接口转换深入到更复杂的业务逻辑展现，实现了真正意义上的数据处理功能。

The practicality of using rough set to reduce the date was discussed, in this paper, and the interval-valued continuous attribute discretization by applying self-organizing map neural network clustering was proposed, too. This article proposes a simplified indiscernible matrix's method, which reduces the example's condition attribute and eliminates the redundant information of the date. What's more, it provides the methods used to diagnosis compressor's faults based on the intelligence hybrid system by adopting the MATLAB neural network workbox. At last, the functional modules which make up into intelligence hybrid system for fault diagnosis was introduced, including: data acquisition module, date preprocessor module, date reduction module, neural network module, fault diagnosis module and fault expressing module. Here, the article also gives the flow of work of all the above modules.
