The design of the data storage abandons the abuse of traditional database low query efficiency. not easy to maintain. long development cycle of disadvantage, by combining XML and relational databases for data storage, satisfies the characteristics of the editor's information quantity and high speed running of the electronic patients. In the software module, the modular development method of the transplantation is adopted, "Electronic patients" case editing module can be ported to different medical teaching or rescue system software which. It provides a software which can effectively solve the contradiction between efficiency and development efficiency, achieve quick and easy process, becomes a stable and secure software systems.
