Comparison And Implementation Of CORBA Services And Web Services

Distributed object technology is a kind of object-oriented technology developed with network which is distributed computing technology and the combination of object-oriented technology. Distributed object technology research in each node distributed in the network how to writing, common objects how to complete the task. The OMG organization has formulated the CORBA standard, is for the purpose of unifying the interoperability between isomerism system, Put forward the concept of "soft bus" and implemented the feature of software bus in "plug and play", so as to improve the software portability, reusability and interoperability. In order to solve the distribution and heterogeneous brings "island" problem, OMG organizations put forward common object request broker architecture, to enhance the software interoperability between systems, and realize the information system effective integration within the enterprise. Distributed object calculation has been widely used in communication and finance industry, realized the object of interoperability between transparent and solved the many problems in enterprises. Distributed computing technology is the key to realizing distributing system, Web technology can easily overcome the defects of traditional distributed object technology. According to internal, corporate and business process integration between the existing resources, to really cross-platform, cross-language integration across the network aims to become an important issue IT industry.In order to solve the problem of enterprise, CORBA has ability to solve complex problems, high efficiency, transparency big, safety higher characteristic, but Web services do not have this feature, while Web services have the freedom to traverse the firewall capabilities but CORBA do not have this feature. Therefore, in the age of the Internet, solving distributed research both integration technology is a very good direction, also is the necessity of the development of technology. In this thesis, we study in the following areas of work:We study the existing framework, and compare the advantages and disadvantages between the various integration frameworks, and put forward a feasible of CORBA/Web services for integrated framework, using CORBA services to provide effective solutions for enterprises. Focused on the research of CORBA/Web services for interoperability gateway, we try to study in HOP agreement and SOAP agreement from the communication between the solution, and realization of interoperability gateways.Then we analysis the performance of the new integrated gateway framework in the aspects of efficiency and analysis the new integrated system compared to the traditional superiority of integration solutions.At last the new integrated system was used in modern financial service system and realized.
