Design And Realization Of Economic Forecasts And Analysis System Based On Data Sharing Platform

With the rapid development of economy and information technology, large-scale software systems, which are in purpose of economic data collation, analysis and forecast, begin to embark on the stage of history. In this large-scale software systems, distributed software systems have some incomparable advantages, such as solving data link problems in decentralized organization, balancing the load, reducing the interference between various types of data, and providing high reliability.In this paper, we explains how to build a data-sharing platform based on economic forecasts and analysis system and large-scale data sharing platform concept. We use software engineering knowledge to illustrate all the aspects of procedure, (i)design of the system's functional and requirements analysis, (ii)details of design, and (iii) implementation of demand. And finally we build one integrated system, including set of data collection, data query, statistical analysis, data interface and other functions, for the analysis of economic forecasts and providing a solid scientific basis.The current system uses J2EE technology which is popular in this industry. J2EE technology provides fully surport to EJB, Java Servlets API, JSP and XML technology, and brings the scalability, flexibility and the ease of maintenance of the system.B/S application model and graphical interface are use in this system with a simple and efficiency operation, which brings open, interactive, efficiency and other notable features. It also uses a data warehouse, webservice and more advanced technology, resulting in a stable and efficient operation for the system. The main objective of system design relies on a large data-sharing platform, based on which, a database platform is established, providing the appropriate platform for the sharing of data to support the need to meet their business.
