J2ee-based Pharmaceutical Enterprise Information System Framework Design

With the rapid development of the medicine industy, it grows highly intensive for developing the medicine systems. Nevertheless, problems existing should to be solved while practicing: (1) to build framework of the information system for medicine enterprices (2) to improve the maintainability, reusability, expansibility and security of applications system (3)to solve the problems like data exchange, communion difficulties and data redunance due to the heterogeneous system in a enterprise. As to these technique nodus, this researchs and extends some open source frameworks such as Struts, Tiles, Log4j, OSCache, Hibernate and so on, try our best to encapsulate some operation which is independent of business, offers the abstract class of encapsulating common behavior and the logical, canonical programme interface, designs the Enterprise Information System Framework(EISF) which is based on MVC pattern.At first, it is analyzed the current status of enterprise application system, and it is defined the functions of EISF base on what, it is enhanced on how to solve the problems of the software layer of the system, middle layer and the layer which provides core sevice to EISF. It is focused on the settlement of how to log in at one point, the model of Enterprise Application Integration(EAI) which based on Web Services, the designment of Cache module, the security subsystem which is based on Secure Socket Layer(SSL) and Role-Based Access Control(RBAC), it is analyzed basing on Asynchronous JavaScript and XML(AJAX), it is developed the client validity check engine, dynamic cascading menu and common, dynamic tree structure groupware, and the independent persistence layer. At last it is analyzed the application of EISF in management information system of pharmaceutical enterprise.
