A Design Of Online Homework System Based On ASP.NET

Information technology plays a more and more important role in many fields, each field is also actively promoting the informationization construction, such as the field of education. Primary and secondary school education in China, and even higher education, homework is an important link of improving teaching level. The traditional mode of operation management requires a number of links, such as arranging assignments and homework, which requires teachers a lot of energy, will increase the work intensity of teachers. With the development of computer technology and network technology, the scope of its application in the field of education is also more and more big, the daily office business to the campus card, in this context, the study of online operation system is also more and more, it becomes the development trend of future school.The system uses a standardized method of software engineering development, development process consists of several steps: demand analysis, system design, detailed design, system realization. This paper firstly introduces the development tools and key technologies of the system, the system uses the ASP.NET platform in C# technology, combined with SQL Server 2005 database to realize. In the requirement analysis stage, in the way of the use case diagram to determine the system requirements include, the system maintenance module, data management module, job management module, performance management module, management module and message notification homework answer module is composed of six parts, and from the performance, operation and safety analysis of three aspects of non function the system needs to meet the demand of. In the system design stage, topological structure of the system and function structure are described, and the activity diagram of each module of the system design in detail, in addition, also has carried on the system design and database design. Based on the system design, completed the online operating system code realization, and design the corresponding test case for each function, according to test the system, after completion of the test, the system errors are perfect. It is a difficulty to implement the SMS function, These implementations are: SMS CAT, SMS gateway and The third gateway, the system chooses The third gatewayThe system has the characteristics of stable operation, easy to use.The system has been successfully applied to the operation management of a university, system application as an interactive platform between teachers and students, students can submit homework online, teachers can online correcting homework, play an important role in improving the teaching quality of the school.
