The Design And Implementation Of Software Quality Assurance System Abaut Guangxi Taxation

Tax-related softwares are to improve the application level of information technology in the tax system and to connect the tax business and information technology.On the one hand,the quality assurance of tax-related software development can maximize the requirements of application software,on the other hand,it can help to realize the information construction of the tax system,so it is of great significance.Through the software quality assurance,the software project execution process can be monitored,and then the corresponding software problems can be found and solved in time.The designing of Software Quality Assurance System provides reference and standardise for Guangxi Taxation and the future work.The system of this thesis is based on.NET three layers architecture,and designed by integrating Ajax technology,IBatisNet and Castle architectures.In order to decrease the transmission of unnecessary data between servers and browsers,Ajax technology is added in ASP.NET technology in the User Interface layer.And by the virtue of the asynchronous refresh technology,this system enhances user feelings.In Data Persistence layer,the mapping between database object and domain object is completed by IBatisNet architecture which can bring more freedom for exchanging to though some SQL sentences are needed to write manually.the overall use of Castle framework makes the dependencies between the builds all managed by the container,thus reducing the coupling of the system.This archtechure not only makes system low coupling,high reusability and maintainability,but also has low cost to study.According to Process and Product Quality Assurance(PPQA)of CMMI process management,The Software Quality Assurance System of this thesis is designed on the basis of PDCA("Plan-Do-Check-Act").Following the analysis of requirement,the designing of system architecture is designed and the particularize design shows the detail logic in the system.In the end this thesis summes the design of the Software Quality Assurance System.
