Due to the conflicts between optional database development platform and application development technology,existing in our current Hospital Information System(HIS)development,firstly analyzes the character of post-relational database Cache which is object-oriented and the comparative advantage of relational database.Based on Cache,it develops another Web application development HIS thinking.Such HIS system takes modular design concept and sets up three-tier structure coming from Cache Server Page(CSP).This three-tier includes data-access layer,business-logic layer and page-show layer.And then,it goes into the discussion of HIS application technique.The practice result presents that such post-relational database Cache HIS comes with fast,stable,easy maintenance and low cost advantages.Compared with relational database system,it has more wide range of applications.
