J2ee Design Patterns And Uml In The Eai System

Enterprise applications integration technology (Enterprise Application Integration. EAI), is one of the important means of upgrading their internal systems, achieving business goals and increasing the competitiveness of enterprises and is the currcni computer application development trends. Along with the rapid development of communications and computer technology, the model has expanded in almost all areas of software branch. It is not only specific software development techniques and strategies, but also on how to treat a set of software systems and real-world relations, the issue of what perspective to study the issue and fellow, and how software systems tectonic software methodologies. The background to the actual project, the master specific projects conducted in-depth discussions. The specific description of the current J2EE technologies and highlights its design model for J2EE related to the study and application of technological advances in the EAI approach to EAI development trends last a look.Enterprises and institutions are increasingly dependent on the operation of computer systems and network technology, the growing demand for operational systems. Operational system requires not only greater usability, but also greater extension and compatibility to reduce overall system development maintenance costs. In recent years. computer technology constantly emerging new fields, such as enterprise application integration technology, technology components, web technology and network technology, and so on. Use these technologies to achieve high system availability and expansionary and greatly reduce the overall system cost of ownership.The author participated in a graduate center information systems development work. The system primarily use enterprise application integration technology, J2EE technology, UML modeling technology to achieve high system availability and expansionary, and that legacy systems to integrated applications. In the development process, the author made depth study on this basis, the completion of this thesis.The first theoretical foundation for enterprise application integration research, made use of the current epidemic UML modeling techniques for analysis of the system design, the use of enterprise application integration technology programs: and establish a system of research and development objectives, namely, to build an integrated enterprise applications, both to adapt to the new system development. It's also suitable for the maintenance of old systems integration and made a simple conclusion to the problems in the system and the follow-up jobs.
