Research And Implementation Of Enterprise Information Portal System Based On SOA

In the process of promoting IT-based industrialization,the enterprises often establish within a large number of application subsystems,so create a different set of problems to solve, such as island of information, unstructured information, repeat development and so on. However, all applications and data are integrated into the information management platform by Enterprise Information Portal, which achieves the sharing internal information and knowledge effectively, and is flexible business process reengineering. As a consequence, development and application of EIP is a new research hotspot to further enhance competitiveness.First, compared with the traditional EIP architecture, this paper has researched Service Oriented Architecture which is the best solution for the EIP system, and form the theoretical knowledge of SOA, researched Web Service technology the best method to achieve SOA. The paper has introduced the Web Service specifications in detail, including Extensible Markup Language, Simple Object Access Protocol, Web Services Description Language and Universal Description Discovery and Integration. Second, the paper has in-depth studied the design requirement, use-case model and business process of the EIP system under the background of coal mining enterprises, designed the main modules, and analyzed how to build SOA, service interfaces and business model. Meanwhile, top-down object oriented analyzing method of the service is adopted. The system has extracted important business functions as services, and processed fine-grained division for services which provide the service model. Then, the paper has researched the EIP system structure, three-tier architecture design patterns, which are consisted of data access layer, application support layer and presentation layer. Building of SOA-based framework for EIP system infrastructure has showed the Web Service operation mechanism. Through the.net platform, the system has realized Single Sign-On, customization, business processes of the information, knowledge and system management, data integration and other functions.Finally, the test has verified the running correctness of EIP functions of the system and the feasibility of SOA, so it reflects good integration capabilities and service-based process. The result has proved that this design is feasible to achieve the desired goals. Meanwhile, the features and advantages of SOA which is the main trend of system architecture provide the best theoretical basis and solutions in the future.
