Reseach On Marching-On In-Time Scheme And The Fast Algorithm Of Time Domain Integral Equation

With the rapid development of computer technology and the improvement of network technology, enterprise informatization is received more and more attention, the enterprise management model transferring to network and information management. And financial information networked is an important part in financial management system which requires the financial software development must adapt to the new network requirements. the development of such a convenient, easy-to-use management system has important significance. But the current domestic enterprise financial informatization situation is not optimistic. From the point of statistics, only 49% of small and medium-sized enterprises is about to start the construction or have implemented financial informatization, and the level of construction is uneven. is still at the lower level.To cure the above problems, this paper adapts the latest computer technology, which combines with the new management mode and management concept, and inherits the traditional development mode of financial management system, thus, making it embody the value of enterprise financial system and the management status of enterprise well. What’s more, it can analyze the data to make full use of the enterprise financial information resources, so as to improve the level of financial management, provide support to senior management and decision-making, and adapt to the development of today’s modern enterprise. This paper also adopts the J2 EE technology which possesses the open, cross-platform, good expansibility and other performances in system development. At the same time, this paper adopts international standards of SSH three-tier architecture, separating the application presentation layer, logic layer and data layer separation, thus ensuring the whole system is flexible and efficient. The main contents are as follows:1. This paper analyzes the concept and research background of financial management system after referring to the related literatures. And it also put forward the design idea, the key technologies adopted and the problems to be solved according to the current development of enterprise financial management system at home and abroad. What’s more, this paper expounds the development platform of enterprise financial management system and the related technologies.2. Combined with the present situation of enterprise financial management system, from the enterprise business process, vouchers, cashier, books, accounting statements, reports, related infrastructure and the setting up of system management and other functions and from the nonfunctional perspective of system usability, maintainability and extensibility, this paper has carried on a comprehensive analysis to system requirements. Through the demand analysis, this paper also designs and elaborates the overall system architecture, main function module and database, and presents E-R diagram and a database table of the system, clarifying the overall system architecture and function.3. On the basis of requirement analysis and system design, this paper uses the J2 EE architecture, SSH framework and Jsp technology, the MVC pattern, Ajax technology to implement enterprise financial management system. According to task demand, this paper also tests the enterprise financial management system function and performance, and puts forward solutions to problems arising from the test.4. In order to improve the performance of enterprise financial management system, this paper also proposes optimizing paging algorithm, the cascading menu without refresh Dom4 j technology and XML parsing algorithm. After testing, the system has made great improvement on the overall performance.
