Research On The Key Technologies In The Society Network Audit System

With the development of the information technology and network communication technology, computer plays an important part in audit department. The aim of the Society Network Audit system is to combine the handwork-audit and computer-audit, and process the audit in the mode of network. According to the theory of modern software and technology, this thesis analyses and studies the computer-audit in the mode of network. The SNA system requirement analysis has been done firstly, and then the whole system design and detailed design have been implemented, and also some resolve schemes to the problems have been put forward.Firstly, based on the principle of the Society Network Audit system development, the requirement and specialty of the audit of social security are detailed analyzed, and the whole system architecture is designed which consists of the function modules compartmentalization, the system flow of data and control, and the network topology.Secondly, some aspects which need to be thought about are put forward toward the mode of network, including of data collection, data dealing and visualization, and the resolvents are given out in the thesis. The feasible method an the design about security of data collection are offered in this thesis, and the dealing of the XML documents compress is detailed discussed, and a model of XML compress based on XOEM is given. The design and realization of data dealing module and visualization module are offered in this thesis. The query optimization, SQL optimization and the speed optimization of accessing database with Java language are studied and discussed. A method of data filter to scatter diagram is offered during the application of visualization module.At last, the work that has been done in this thesis is summarized and the next target is advanced.
