Design And Implementation Of Degree Management Information System For Graduate

Degree Management Information System for Graduates is a synthesis management system developed by using advanced design methods and technologies. It is established in the real degree management work of Shandong University and it involves every stage of the degree management work for different users. The system is used to solve a series of realistic problems effectively such as the data redundancy, the resources waste, the imperfect surveillance mechanism, the statistical work detention and so on. The goal is to achieve management of the whole process of the degree management work, so as to improve the impartiality and efficiency of thesis appraisement and degree information management work.The Rational Unified Process is used as development tool and UML is used as description language for analyzing and design in this paper. The system adopts object-oriented idea on the degree management business of requirements acquisition, requirements analysis and system design. For the user and system characteristics, the system implements many function modules in the process of degree management, for example, thesis quantitative management, qualification examination and thesis evaluation, defense management, degree awarded and degree offered management, historical data management, using both B/S and C/S architecture model in form , using multi-level software functional framework in function, based on the MVC-based technical Structs+Spring framework and UIMS user interface management system framework in technique. The system uses java as the programming language and uses XML configuration and Dao, Hibernate related technologies. In the area of security, the system adopts role management based on authority management to enhance system security. Through the external interface to provide query service, and the system of internal business processes to provide a complete interface to operate or query data, the system achieve internal and external data on the system of information sharing. In the system analysis, the requirement acquisition methods in system development process are explained and a detailed description for system and business processes in general business is carried out. Also the functions of five modules as well as the relationship between the modules are described. It focuses on the analysis of students' degree state, the process of graduate state transition and the process of the state regression. Through static modeling on basic information of students and papers evaluation, a detailed description of papers evaluation classes and the relationship between the classes, we obtain the design class and database model in the system. It also focuses on the database of basic information of students and papers evaluation related table views design. Rules engine is used to solve the description of complex businesses and to strip the business rules and actual codes in this way. The data which was transformed by XML configuration can be re-processed and export directly to the national offer degree system. It uses images splitter design and images smoothing algorithm to solve large files storage such as images and to improve the efficiency of input and output. The expansion of system format and content verification improves the fault-tolerant and feedback ability of the system.Now, part of the system has been used successfully by Shandong University degree department. It has a great effect and makes the cultivation management of postgraduates more efficient.
