【摘要】：机房管理的目的是为教师和学生提供更好的上机实验环境和资源配置,从而提高上机实验教学的效率。从目前的情况来看,大多数农林院校都没有建立起一套行之有效的机房管理系统。针对目前农林院校机房在管理过程中存在着的信息化程度不高,相关数据无法得到有效应用的问题,基于软件工程中设计模式技术,设计并实现了一套机房管理系统。系统主要包括学生使用模块、教师使用模块、机房管理员使用模块、系统管理员使用模块四个部分。对于每一个系统模块,根据不同角色用户的使用需求,分别设计并实现了相应的功能。系统不仅能够满足用户的使用需求,而且从系统的性能角度出发,利用面向服务架构方案,以及GOF设计模式,对主要功能模块的设计进行了优化。针对目前机房信息管理系统存在多种类别数据库管理系统,数据处理接口不统一的问题,采用抽象工厂设计模式,屏蔽不同数据库管理系统的操作差异,为上层的数据操作提供统一的接口;针对机房中实验材料管理功能开发过程中,实验材料的种类与所应用的上机实验对象之间耦合性较大的问题,采用桥接模式,将具体的上机实验软件与上机实验操作相分离,从而提高系统功能的灵活性;针对系统中的学生与教师的机房预约功能,在可用机房资源方面存在差异的要求,采用模板设计模式,避免了代码冗余,同时提高了可扩展性;针对课件上传发布过程中有可能会要求扩展操作的需求,采用装饰模式,保证了在扩展功能的同时,原有的类不被改动。机房管理系统能够有效地提高机房各类资源的管理效率,同时为教师、学生、机房管理人员提高效率提供平台,具有较好的实用价值,同时,将设计模式应用于系统开发中,以提高系统的可扩展性和可维护性。
[Abstract]:The purpose of computer room management is to provide teachers and students with better computer experiment environment and resource allocation, so as to improve the efficiency of computer experiment teaching. From the current situation, most agricultural and forestry colleges have not established a set of effective machine room management system. In order to solve the problem that the information level is not high and the related data can not be applied effectively in the management process of agricultural and forestry colleges a set of computer room management system is designed and implemented based on the design pattern technology in software engineering. The system mainly includes four parts: student using module, teacher using module, computer room administrator using module and system administrator using module. For each system module, the corresponding functions are designed and implemented according to the needs of different role users. The system can not only meet the needs of users, but also optimizes the design of main functional modules from the point of view of system performance, using service-oriented architecture and GOF design pattern. In view of the problem that there are many kinds of database management systems in computer room information management system and the interface of data processing is not uniform, abstract factory design pattern is adopted to shield the operation differences of different database management systems. To provide a unified interface for the data operation in the upper layer, the bridging mode is adopted to solve the problem of the greater coupling between the types of experimental materials and the applied experimental objects in the development of experimental material management function in the computer room. In order to improve the flexibility of the system function, the students and teachers in the system have different requirements on the available computer room resources for the purpose of separating the specific computer lab experiment software from the computer lab operation, and improving the flexibility of the system function, and aiming at the difference in the available computer room resources between the students and the teachers in the system. Using template design pattern to avoid code redundancy and improve extensibility; aiming at the requirement of extending operation in the course of uploading and publishing courseware, the decorative mode is adopted to ensure the expansion function at the same time. The original class is unchanged. The computer room management system can effectively improve the management efficiency of all kinds of resources in the computer room, at the same time, it provides a platform for teachers, students and computer room administrators to improve the efficiency. It has good practical value. At the same time, the design pattern is applied in the system development. To improve the scalability and maintainability of the system.
