Research And Developing Based On Primary And Middle School Management Information System

With the overall generalization of quality education and the improvement of the information level of the primary and middle schools in Jilin province, large changes have taken place in the fields of the management way of the primary and middle schools. In order to meet the need of the improved management level of the quality education and campus network platform, we developed this set of the Management Information System of Primary and Middle Schools. It involves each link of the school, providing an advanced network system platform and a stabilized and efficient working environment for the school to manage its routines. It achieved the goal of the timely feedback of information through the information resources sharing system, and of the timely adjustment of the school management. With the application of this system, primary and middle school will followed digital, scientific, efficient management level. It is helpful for the schools to establish qualification management system and performance assessment system, and finally free the faculty from the heavy handcrafted work.First, the paper analyzes the situation of the management software of the primary and middle schools in Jilin province and explains the importance and necessity of developing a set of management information system for the schools in the province. Then based on the development of the Basal Information Setup System and Education Administration System, the paper offers the whole course involving from system analyzing to modeling and to realization of this system in detail. The paper also gives some key techniques met in system design.OOP is another method of observing application. Through OOP, the application program will be divided into many small independent sections, which can be combined to create application. The most important advantage of OOP is reuse, namely, we can create one-off components and use them again and again. Further more creating model scientifically and reasonably is a successful assurance to a project. If reasonable modeling can't be created, it is very difficult for a project to be finished according to the plan, and even the project will have been completed, the maintenance and modification of the system will be very difficult because scientifically and reasonably modeling isn't be created. UML is a visual modeling language of OOP. Through UML, software-intensive system can be of visualization, construction and documentation .The paper explains on how to use UML to model system in details, and gives parts of use case diagrams, interactive diagrams, component diagrams, deployment diagrams of the above two modules. Two-layer application, which is constituted of database Server port and the Client port, is a C/S model early. It's major drawback lies in its poor flexibility, which results in the waste of the system resources and network resources. With the enlargement of the business logic and complexities of application, the difficulty of its development work is also increasing, and finally its poor expandedness will appear. In order to develop an application with high expandedness, multi-layer architecture is needed. The basic of multi-layer architecture is three-layer. This three-layer architecture resolved the problem of the two-layer one, and made Business logic independent, forming user's interface layer, business logic layer and data stored layer. Each layer is relatively independent, and communication from one layer to another is performed through public interface. The loose coupling between layers can simplify program design, and improve expandedness of program. The component is the base of three-layer to realize expandedness; it inherits and develops the method of OOP, emphasizing the real reuse of software. Through adopting the method of program design based on COM, we can design and realize component, which has high reusage and expandedness. COM+ is the outcome of COM and MTS, including all advantages of DCOM and MTS, and it provides more servers of system a good solution to quickly create...
