Database access middleware is the most sophisticated of all kinds.It supports communication in the application and data sources,which can be local or remote and isomorphism or heterogeneous.Data access middleware is responsible for communications data in the access client and database server,and provides application services.By using data access middleware,the user can issue on the client data query command,the server can complete the data query and sent the results back to the client.The development of database access middleware is discussed,and a structural model of database access middleware is presented.The model is implemented by the six components,including customer interaction modules,remote access module,the security control module,the buffer zone,operation evaluation module and connection management module.
