| Recently, enterprise application is going to hold mostly in the field of software development. In the large and complex application, J2EE and .NET already become the main platform. With the increase of requirements and development of technology, single platform and technology cannot satisfy the requirements of company. It is necessary for the company to integrate the new technology and platform to the existing system. As an effective way for integration, interoperability could fix this problem.The thesis firstly study the essential technology for developing the enterprise application program, including AWT and Swing for Java application program, and MVC pattern in Java system. Secondly, the thesis introduce Spring and Hibernate framework for building lightweight J2EE system. Thirdly, the thesis introduce the traits of .NET framework and C#. In the part of interoperability, the thesis discusse JNI and COM for implementing interoperability. At last, the thesis introduce SQL Server 2005 database and Microsoft Enterprise Library for enhancing the reusability.Based on the study of essential technology, the thesis design and implement a clinical information system for implementing interoperability. The system has three layers, which are presentation layer, business logic layer and data layer. It could effectively achieve the separation of user interface, business logic and data, and enhance the reliability, scalability and manageability. In the part of system implementation, based on the technology of AWT, Swing and the integration of Spring and Hibernate, the modules of patient list, patient management, pathway and user security are implemented for java application. Moreover, based on the business control and Microsoft Enterprise Library, the module of patient assessment is implemented. After that, the interoperability is implemented by JNI and COM between different platform, and it finally achieves the design requirements of the system. |
