The Design And Implement Of Enterprise-Integrate-Application-Sill System

More and more enterprises need to establish business information management systems with the rapid development of economy. Since market develops so fast and enterprise management is not normlised, a lot of managing patterns are still in feeling about phase,.which brings about many demand obscures and levities to the enterprise information management system. So the development and maintenance of universal enterprise information management systems becomes very difficult. Therefore, it is urgently required to separate the fast model building of enterprise management and the business construction from the application logic, and to provide a platform that can define application system.This paper describes the study and devlopment of an Enterprise-Integrate-Application-Sill System (Entasill). Entasill doesn't tend to provide a middleware or application server, but to build an independent application service platform by adopting the middleware and application server. And it can flexible extend business and management on demand. The application software provider and enterprise self can rapidly deploy and apply the Entasill for their information management system. The paper is creative in technology, and no other domestic software company do the same study at present.Entasill is developed according to J2EE technic specification, synthetizes many techniques such as Java, XML, HTML, MapXtreme, Database and Spatial Database, and utilizes Web server to supply the enterprise application service. It is able todefine application system, function module, data and its control, inquiry and report on the basis of the actual demand. It achieves the map administration function through integrating MapXtreme middleware, and implements the flexible purview control strategy by supplying user/purview administration module.Concrete work is as follows:1. A lot of components used in HTML page customization are encapsulated to reduce the codes of program and ensure the unification of interface styles.2. Design and realize high efficiency administration of database connection pool, and achieve the database independence to some degree.3. Open up a self-administration and self-extending core platform, which unifies the request entrance and implement the system configuration, service dispatch, service administration and business abstract handling interface.4. Design and realize many function modules such as user/purview administration, module administration, prime data management, table definition, field definition, data management, formula definition, inquiry definition, report definition, log administration and map administration.5. Successfully establish Mobile-Resource-Management system with Entasiii, which has been tried out in Sichuan Mobile Communication Corporation.
