The Design And Implementation Of The Nine-year Compulsory Screening System

With the development of computer network technology and the advance of nineyear compulsory education, the census of nine year compulsory education becomes animportant task for many education workers. The current method of census is artificial,so an intelligent, efficient and informational census system is needed urgently. Thecensus system developed by us realized an informational platform for teachers, schools,units and leaders. It improved the efficiency for census.The system adopts JAVA technology, SSH frame, EXT components and B/Sarchitecture. The system has good maintainability and scalability using JAVAcomponent. Front plat uses EXT components, Client plat has a friendly interface and theoperation is easy to use. The data of the census system are saved in SQL database. Theentire system is composed of system administrator module, teachers’ module,school-age children management module, the unit information management module andintegrated query module. The complete realization of the nine year compulsoryeducation is advantageous for relevant departments to carry out management, forleaders to develop scientific principles and policies and for improving the quality andcoverage of nine year compulsory education.This paper is a summary of the census system of nine year compulsory education.The main work of the authors includes the following:1, for the current nine-year compulsory education to conduct research surveys,based on design goals and principles of software engineering, to business requirements,functional requirements, performance requirements, operating environment demand acomprehensive analysis, design of the nine-year compulsory education in the censussystem.2, Using java development language+EXT framework components and SQLserver2000database technology to achieve a nine-year compulsory screening system forschool-age children to achieve the management, report management functionalityrequired. Solve the nine-year compulsory education, low efficiency in the census survey,census data to isolate the problem. 3. The specific implementation of system is based on SSH framework: thepresentation layer through the JSP pages to interface. Business logic layer complete thebusiness logic through the Spring IoC container that provides component businessmodeling which cooperation object data processing (DAO),and provide the transaction,buffer pools and other containers components to enhance the system performance andensure the integrity of the data. But which relies on the Hibernate, that the objectmapping and database interaction, processing DAO component request of data, and toreturn to deal with the results in data persistence layer. The system implements thefunction that school-age children management and report management. As well assolves many questions such as the low efficiency of the nine years compulsoryscreening, and the problem of census data isolated.
