Design Of Enterprise Credit Rating System

Credit Rating is an important part of a social credit system and infrastructure. According to a standardized rating system indicators and standards, using the scientific assessment methods, perform rigorous assessment procedures market participants to conduct a comprehensive understanding of relevant information, analysis, in the next period of time to fulfill its commitment and the ability to provide a comprehensive judgment on the various risks that may arise. And express its credit rating by certain symbols.Because this assessment activities need to deal with a large amount of data and the operation is relatively more complicated process, mistakes. And the preservation of historical data is difficult to use. With the development of society, the enterprises to be evaluated become more and more, and this have hindered the development of the assessment department .Under such circumstances, there is a need to assess industry intelligent automation "Enterprise Credit Rating System." this system can be used not only to evaluate trades for the day-to-day business assessment, but well preserve, use historical data, and the overall contestant analysis of the whole enterprise, the calculation of the annual defaults issues. Meanwhile, in the wake of the development of the times, the constant renewal of enterprise standards, the system has the flexibility to update the assessment standards really intelligently.In view of system security, open, high performance, and stability, the development of systems is based on J2EE framework. Consider the flexibility of the system and the function of the system, the traditional C/S system model is abandoned while the more flexible, J2EE-based framework B/S system model is adopted. And in light of the characteristics of this system, some flexible layers are added to make the whole system clearer, and the development and maintenance to be easier.This paper mainly discusses framework of the system. The system includes information on basic, basic business information, financial analysts, credit rating, credit-rating report and the risk management system, network information inquiry system. The enterprise information system is characterized by a variety of information of all kinds of enterprises. The credit rating standard, model calculations also vary .So the system is quiet difficult to tap.In the process of developing, we are using object-oriented analysis and design method for the analysis and design of the framework for the system. In the business layer and data layer hierarchical model, the prospects sonPage is increased, in the background layer, the ORMap and ActionBean layer is added. So the system raised the maximum extent of the code reuse, and reduced the development and maintenance of the workload. Considering the size of the system, the relatively stable SqlServer2000 is used. By using the weblogic connection pool, greatly reduced the performance of the entire system when large number of database opened or closed. This application enables more closely integrated, efficient operation of the whole system. The logic on the overall system configuration file makes the system thread more lucid. And greatly enhance the readability of the system and reduce the difficulty of maintaining, and also greatly increase the level of system stability.
