Design And Implementation Of University Network Office System Based On J2EE Structure Technology

With the rapid development and widespread application of internet/intranet, promoting the college office automation, networking and electronic has been a general trend. At present, the office automation system designed by conventional Clien/Server mode could not well satisfied the need of network office and could not fully fuse the feature of new techniques, so it could not bring the advantage of new management mode into well play. According to these situations, with the design of a network office automation system for universities, this paper summarizes out an office automation system based on J2EE.This article comes out of the development of a J2EE-based office automation system project. The OA (Office Automation) system studied in this paper was based on "The Network Office Automation System of Weifang Vocational College" of version 1st. Following the analysis of the special needs of OA users, how to use J2EE-based MVC model in the design of development platform is discussed. Then, the design mode which logically separates application control, business logic and display is used to design a typical domestic network of office automation business development platform. Finally, server-sided programs are developed using Java.Applicability is implicit in the program design philosophy and scheme. The main purposes of this system is as follows: firstly, ealizing the automation of file management and office business to improve efficiency and optimize management, secondly, realizing the formalization, electornicness and standardization of daily operations in various departments to enhance the manageability of related information, and finally, realizing online query to achieve the goal of "paperless" officing.The main work accomplished and the results obtained in this thesis are as follows:1. The existing systems of colleges and universities were analyzed to identify the needs for the overall planning and design of new system: including demands for functional improvement, business logic, system design, function module and database analysis.2. All eight function modules are realized in this system. With system function design and user interface design, the separation design mode is adopted to ensure the separation between the revision of the back-office rule and front-office user interface. This also ensures the scalability of the system design.3. Various software development technologies, such as compression and decompression, data upload and download, etc. are used integrately to guarantee the system generality and migration ability. Reference instances are established for some business functions, e.g., entry, query, application, etc.. Some general function modules are abstracted and developed, e.g., user authorization module,information dissemination module, etc..4. The interfaces between modules and module functions are defined clearly and developed seperately.
