Network Control System Design And Implementation Based On Flex And J2EE Technology

With the development of computer technology and improvement of network performance, the enterprises vigorously carry out the information construction, actively deploying the network system across the country. Due to lack of effective information management platform, leading to the center cannot unity to control the server all over the country, causing the server load uneven, and cannot deploy large-scale collaborative tasks, making the overall low utilization of network resources. In addition, because traditional Web application demonstrate effect is too simple, cannot intuitive and clearly embodiment the distribution of system resources, demonstrated the complex data various dimensions and change trends, leading the users get less effective information throughout the system, and user experience is relatively poor.This paper is intended to propose a network control system which can management and control the enterprise’s servers across the country. Easy for user to intuitive and convenient view the nationwide server distribution situation, task configuration situation and the servers themselves running trend of changes, enhance the system function, improve the user business processing efficiency, and thus enhance the system utilization.This paper begins with the introduction for RIA technology, proposed to realize the Web RIA network control system by Flex technology. System enrich front desk display effect through various Flex data visualization technology, meet the system’s complex data multi-dimensional display and trend of change display; By studying the current mainstream map services, this paper first time realize the flex-based offline map browse by proposed ArcGIS engine load the Google tile maps, meet the intuitive to display the servers distribution situation across the country.Later, by analyzing the requirements of the network control system, combining with the system’s network structure and the main business logic, this paper design the system database and representative function modules. Build the network control system architecture by using Flex framework and Annotation configuration, verified the feasibility for offline map browse and data visualization in the system, designing and implementation the system function modules, and complete the user’s development needs.This paper proposed a Web RIA network control system, it not only unified management the server resources across the country, but also has the improve resource utilization and optimize overall network performance characteristics. It also has several advantages:The system can be deployed in an offline environment, reduce network bandwidth costs, enhance the data exchange rate, and at the same time also increase the security of the system; The client in RIA applications can store the application’s state, so no need to exchange data for each operation, thus reduce the system response time and reduce the server hardware load; Flex technology will compile the application as a Flash file which can be deployed in most mainstream browsers and operating systems, has a good platform portability; Flex can also provide fine front desk display effects and a variety of data interactive solutions to meet user all-round experience requirements; At the same time, this paper implements the system by integration of J2EE technology, which can effectively improve system development efficiency and system operation speed, let the system has a high maintenance, expandability and other characteristics.
