The Design And Implementation Of Educational Administration System Based On ASP.NET

The educational implementation system is planed for the satisfaction of the increasingly complex educational administration work in university,for the promotion of the information circulative speed,for the increasing contact and communication between teachers and students,as well as for the improvement of working efficiency amony different branches.The educational administration system is such comprehensively advanced management methods as administrative science, information science,systematic science and network technique,all routed into one. The system is established by the information administration,which is based on the B/S model,and selects the data base of ASENET+SQL.Server2000 to apply.Focus of the thesis is to design the educational administration system,and employs the typical administrative system by the theory of objects-oriented.The development includes two aspects:the establishment and reservation of the backstage data base;the development of front applied programs.By achieving this system,users can directly visit all kinds of information with in the authority of operation under the netwok environment.During the process of development,the thesis bases strictly on the concept of software project,and makes systematic analysis and design,aimed the technology of directed objects on UML.Uniform Modeling Language(UML) is the one to visible, fully describe,build and documentalize for objects-oriented,especially applied in Rational Unified Process.UML can be used in stage of software engineering project, therefore,the thesis models the views related to UML by using Rational Rose 2003.In the practice of systematic design,the thesis fully elaborates the objects-oriented, the plan for the data base and the mapping methods from UML to relational data base. And it also models the E-R diagram with the help of Microsoft Visio,in the demand analysis of data base.Furthermore,it analyses the functional demands of the users in the system,defines the system services or function units enjoyed by interparticipants, establishes the needed models and detailed division.On the basis of the Use Case Diagram,the thesis enters the stage of systematic analysis,distinguishes all the classes with in the system,establishes the Class Diagram,judges the structure of each class,and finally builds the static models in the stage.In order to describe how the objects interact dynamically in different period of time,the thesis continues to establish the static models in systematic analysis stage,including Sequence Diagram and Collaboration Diagram.It is because of the stratification and carving sub-system that the educational administration system in this sense can be divided into students login model,teachers login model,educational administrators login model and teaching material administrators login model.The educational administrators login model is the focus of development for the whole system,among which can be divided into such models as students information management,teach management,optional courses on line,work load calculation,teaching plan management,and so on.In the state of designing data base,it shines upon the data base model from object models and establishes them in view of 2 mapping relations among the 3 models in data base.To sum up,the thesis has established completed UML models,elaborated the analysis and models in the process of exploitation in details,and provided clear solutions to the applied software.Therefore,it is of great help and value to the reads who are intended to develop software by using UML.
