Research And Application Of Enterprise Information System Based On SOA

Enterprise information technology has greatly enhanced the production efficiency; the application of enterprise information management system enables departments to share information. Meanwhile, the statistical analysis of data for the enterprise can also provide decision-making basis for future development. However, with the continuous development of their business, the original management system to meet the ever-changing needs of the ever-changing business needs, and these changes may lead to large changes in the system or even to re-build the system. SOA-based architecture design package the original functions package into services, use the form of service composition to express business processes, and then it will improve the flexibility of the system, at the same time avoid the trouble of re-building systems or making major changes because of the change of business. In a short word, it can quickly respond to business change.The advantages of SOA are the reusability, flexibility and complication. After years of development, the advantages of SOA are outstanding in series of application projects. As predicted by Gartner Group, SOA has become an important field of modern application development topics and the dominating software engineering development method, and mainstream enterprises have already invested a lot on understanding and applying SOA development technology.The detail work has been done as follow:1. This paper describes the basic concepts and characteristics of SOA-related, and introduced the history and main ideas of SOA. For enterprise application development and integration problems, this article analyzes the traditional solutions, as well as shortcomings. Moreover, compared with the SOA, it illustrates the advantages of SOA in solving the enterprise integration. With the help of the practice works, we demonstrate steps to develop SOA. We also present the problems and difficulties we might meet during the development progress and the principle in SOA deployment and development for the enterprise purpose.2. Service is the foundation and core of SOA, who have a direct determine to the success and quality of SOA implementation. Therefore, this article makes a detailed analysis on service-oriented analysis and design, which pave the way for the future implementation of SOA. First, the service concept is introduced, three methods of identifying the service are presented, and the service coupling and particle size are analyzed. Then, from the angle of the development, service design guidelines and processes, and how to size control in the service design are presented.3. In the guidance of the basic theory, taking marketing management subsystem of MIZUDA Printing and Dyeing Co. Ltd. enterprise information systems for the instance, this paper finally use Web services technology to carry out enterprise information systems based on SOA, combined with object-oriented analysis and design methods (OOAD) and the traditional hierarchical thinking of software architecture.4. In the end, we present the future work of SOA. Integrated with modern activate service technology, we also discuss the feasibility of the intelligent SOA architectures in the future.
