Test is the major means of verification and validation for a complex electromechanical system development process. Test data management(TDM) system unified management of various types of documents, structured data, and other test resources. In the course of the development of large scale system, it involved many types of data, large amount of data to terabytes. At present, most of the TDM used a relational database management system for storage, so there are difficult type expansion, retrieval and inefficient when dealing with large data. The TDM system architecture based on cloud computing platform adopts the distributed technology with ability to achieve high reliability and flexible expansibility. This article describes the system applied three layer architecture based on Hadoop, including cloud storage layer, service layer and application layer of the main composition and function, which work together to achieve the flexibility and expansibility. Based on this system architecture designed a TDM system, which realized the scalability of a variety of heterogeneous data management, and could be used for real time data query. Keywords-cloud computing; test data management; system architecture; Hadoop.
