I. Overview

1.1 Background of the topic
The basic functional requirements of the scientific research management system of a university are:
(1) Realize the management of basic information such as departments, positions, and professional titles;
(2) Realize the management of teacher information;
(3) Realize the application and approval management of scientific research projects;
(4) Realize the acceptance management of scientific research projects;
(5) Create a default and bind it to the acceptance mark of the scientific research project so that its default value is "not accepted";
(6) Create a trigger to automatically modify the project's The acceptance mark is "acceptance passed";
(7) Create a stored process to count the number of applications and completions of scientific research projects in each department; (8) It has data backup and data recovery functions.
1.2 Design tasks and requirements
① Collect and investigate relevant materials and the latest technical information through research and use of the Internet.
②Understand and master the requirements analysis process and basic methods of database systems
③Basically master the basic steps and writing methods of writing design reports.
④Basically understand and master the design methods of ER diagrams and the conversion of relationship patterns according to the requirements of the subject.
⑤ Generate database tables based on the ER diagram and carry out logical design of the database.
⑥Measures to ensure database integrity and security.
⑦Physical design of database.
⑧ Implement database maintenance plan.
⑨ Design and implementation of application systems.
1.3 Development environment and tools
Database platform: MS SQL Server Development platform: J2EE Eclipse
Software architecture: C/S
