Analysis And Design Of Kindergarten Teachers' Learning Exchange System

Firstly, based on the investigation of a kindergarten Teachers Trainings institutions, the problems should be solved are listed. The significance and importance of the project are discussed..Secondly, the thesis proposes the overall design goal of the system. To achieve the goal, the author presents the results of the requirements analysis, including the business, functional and non-functional requirements in detail. Moreover, based on the UML modeling technology, the activity diagrams are used to describe the business requirements. The use case diagram and the use case table are used to specify the functional requirements Moreover, the results of the system design, including the overall design of architecture design and functional modules decomposition as well as the detail design for each module are also presented. The layered architecture design diagram of the system based on B/S Architecture style are elaborated. According to the design principle of "High Cohesion and Low Coupling", the system is broken down into the following main modules:learning situation, learning materials, blog, BBS forum, users and basic data management subsystem. For each module, we present the module design content in detail based on the package diagram, class diagram, sequence diagram and business process activity diagram. E-R diagram and database table are used to the design of database. Based on the database buffering technology, the performance is enhanced. The RBAC access control and the system log monitoring technology are used to achieve the security.Finally, the contention of the research is summarized. Also, the work that has been done is described. The shortcomings of the thesis are discussed and the work that should be done to improve in the next step is discussed.
