Design And Implementation Of Worksheet Management System Based On Java EE

Combining the theory of Object-Oriented Analysis and Design (OOAD), following the procedure of Software Engineering as Use Case Analysis, Object-Oriented Analysis (OOA), Object-Oriented Design (OOD), Development and Test, this paper constructs a management system for supervising worksheet, which contains a Graphical User Interface (GUI) and its supporting database.At the beginning of the paper, the author summarizes the work flow of the worksheet management rules in current situation, and the requirement of the system which must be paid more attention to. Furthermore, the author digs out the real business processes and features of the system. And then, by finding out the detail of the fact, the author explains the necessity of building a worksheet management system.During the work enter the OOA section, according to the result of Use Case Analysis, the author let the overall-analysis first to recover the domain, and draws a conception model which includes all concepts of the problem. Secondly, a concrete detail-analysis reveals the whole processes that mentioned in the Use Case Analysis, and describes the system behavior. The analysis part proves the possibility of the system.Finish the work of analysis, the author shifts the focus from analysis to design. The overall-design is the start of design. It solves the problem of frame work and structure in the whole software. And the detail-design uses the solution of OOA, and devises the question of detail. After the part of design, the project is going to be developed.There are two focal points in development of the system:the use of the frame work and the implementation of the program. The frame work contains the core design pattern of Spring Frame Work, called Dependency Injection. There is a whole revelation to the efficiency of Dependency Injection pattern, and the influence of the pattern on the development. The implementation of the program includes the concrete work on the business. There is instruction of the program of the system and the processes of development. At the end of the paper, the author summarizes the work and the importance of OOAD followed the prospect of the future.
