Applied Research, Asp-based Database Hosting Services

This paper is concentrated on the research and development of theData hosting ,which is a branch of Application Service Providers .Theprototype is a CIMS Project of the first hospital of Xi'an jiaotongUniversity .The research is mainly in system structure ,Access to WEBDatabase and the interface between user and computer.In this paper, the function and performance of this system is firstly analyzed, which is the basis of constructing system structure and marking off function module .The implementation of this system adopts the mode of Browse/Server and the mode of Client/Server, which is a three layers structure. Then the system's security is analyzed. A very important aspect to develop Data hosting system is the application of the technology of access to the WEB database, and this technology is on the developing phase. By analyzing the advantages and shortcomings of many types of popular schemes to access the WEB database, the paper decides the system's scheme which integrates B/S and C/S. Reference the data hosting of oversea, this paper brings forward a user's interface enable tool, which makes user construct interface between single person and computer facility. This system integrates the technology of Middleware, which plays a more and more important role in three-lay C/S (Client/Server) and uses the technology of COM (component) in softwaredesign. When the system run in the first time, the active controls are downloaded to the user抯 browser and user can construct them.The users s interface enable tool in this paper is up to the mustard of end to end service. The ASP system structure and many function modules are same with E-business.
