Researches On SOA-Based Softerware Development And Its Application

This thesis for a new type of software architecture—SOA (Service-Oriented Architecture) was analyzed and applied research. With enterprise-class application development, software gets more and more complex and object-oriented technology has been unable to solve the issue of reusability and maintainability, so designers made a component-based design idea, but unfortunately this is the thinking of a good solution and software complexity of the issue. Today, we are facing such as distributed software, application integration, different platforms, a wide range of mutual agreement and equipment combinations, and so on such a system, and can be eliminated using SOA different platforms and protocols of the issue and the realization of the application seamless integration. SOA an important part is: it is no longer focus on technology as the center of the fine particles entities, such as the type of database or Java objects; SOA to focus on business-centric services, there are business-class size matters. SOA is a framework that the blueprint for a broad range of different technologies and does not require specific agreements or connectivity. So good SOA can help enterprises improve their ability to IT, and with the need to change to meet business needsThe main work of this dissertation was focused on the theory, design and implementation of SOA. Based on the thoroughly analysis of_ SOA, a practical design workflow and modeling method are prompted, and some core modules of a Logistics Information System are implemented to confirm the above conclusion.First, On the base of deeply researching on the SOA theoretical mode, this paper gives us an overview about SOA and the relevant technologies: Web Services, ESB.Second, it analyzes the instance system how to realize the, functions of supply-chain collaboration among enterprises applying with SOA mode according to the requirements. On this basis, a new SOA planning - ESOAD, given its overall design and realization, and its key technology in detail,Then, through a specific example of the application of the detailed implementation of the SOA process, to prove the effectiveness of SOA, the SOA analysis of the design method agile and efficientFinally, the full text of the summation, and to further study the direction and content.
