| The establishment of enterprise information systems in our country presents some problems to be solved while obtaining considerable development: Each application system in enterprises is unable to integrate each other because of the difference among legacy systems. This situation of isolating may bring numerous losses to enterprise. To solve this problem, Enterprise Application Integration (EAI) arises, which based on Web Service technology is the most advanced one at present..NET and J2EE are two major platforms of software and EAI development. The two platforms are similar in function and different absolutely in function realization. They absorb each other and compete each other. For a long time, there is a fierce debate on their own quality between the camps of both sides. But for small and medium companies, independent venders and software consulting institutes, it is more attractive to find the truth about practical performence of the two platforms. Seen from the present situation, it is most needed the comparative research based on the theory of software engineering.This paper proposes a comparative model of Enterprise Application Integration system based on the theories of EAI, common development platforms and popular criteria of software evaluation. It then compares the technologies of NET and J2EE according to this model. This model is based on software engineering thought, referring to ISO/EEC 9126 international criterion, GQM method and SA evaluation criteria, regarding practicability as objective. Through this model, this paper carries on an overall analysis about aspects of EAI system;Through the comparison based on model between .NET and J2EE, it further analyze and compare performence between the two development platforms in EAI.It is hoped that this paper may be helpful to the understanding and choice of EAI technologies and its developing platforms;It is more expected that the model may serve the future comparison of other software systems and products. |
