| Information portal system is an important field of modern computer applications and a complete enterprise solution. It has a very close relationship with the development platform. This article focuses on providing a unified structured rapid development platform technology for the information portal system, thereby the efficiency of software development and code reuse rate can be improved and the deployment and management of applications will be convenient and the system can be integrated gradually and extended flexibly.Firstly this paper describes the role of the information portal and the problems which the rapid development platform wants to solve. On these issues, this article analyzes component technology, the features and advantages of J2EE, design patterns and page display technology. Based on these technologies, this paper describes the design and implementation of rapid development platform of information portal. The platform mainly consists of two parts. One is the server including a core container which provides the living environment for components and various management components. The other is the public development components which provide the infrastructure services for the application development. Then the paper illustrates how to use the platform to develop the applications through an example. Finally, this article compares the platform-based development and the traditional development from different aspects, and then illustrates the advantages of rapid development platform. |
