【摘要】：当前信息的自动处理以及网络式的信息交互方式已经被人们广泛应用。随着高校教育信息化建设的不断推进、学生规模的不断扩大、各种教育模式的兴起，如何及时、高效的计划、分配课程资源成为广大高校面临的主要问题之一，让计算机来管理学生的信息成为各个高校都在积极进行的工作之一。耿丹学院由于学生规模的不断发展，每学期都要在教学计划制定、教学资源的分配上花费大量的人力物力，所以建设高效、及时的教学管理系统成为学院的一项重要的工作内容。在分析耿丹学院对教务管理系统的需求，综合当前国内外类似系统的设计及开发思想的基础上，我们设计并开发了这套“耿丹学院教务管理系统”。在系统建设过程中我们实践了多种软件工程方法，基于WBS成功实现项目任务的分解及计划制定，并通过关键路径方法成功保证了项目主要功能的开发进度，通过制定成本管理计划保证了项目在预算范围内成功开发。基于Oracle的表分区及索引技术成功解决了系统的高并发访问瓶颈问题，测试系统峰值可以实现500个以上的并发访问支持。实现了基于遗传算法进行的智能排课算法研究，在一定程度上减少了当前国内同类系统存在的排课后需要过多的人工干预的问题。在系统架构方面成功实现了基于Oracle RAC的数据库集群技术应用，，成功保障系统对数据完整性、准确性、可用性的要求。另外由于系统最终是支持在公网访问的，所有在系统安全性方面成功应用多种加密方法保证系统的安全性。
[Abstract]:At present, the automatic processing of information and the network mode of information interaction have been widely used. With the development of educational information construction, the expansion of students' scale, the rise of various educational models, how to plan in time and efficiently, how to allocate curriculum resources has become one of the main problems faced by colleges and universities. Allowing computers to manage students' information has become one of the active tasks in various colleges and universities. Due to the continuous development of the students' scale, Geng Dan College spends a lot of manpower and material resources on the formulation of teaching plans and the allocation of teaching resources every semester, so it is building high efficiency. Timely teaching management system has become an important work content of the college. On the basis of analyzing the demand of Geng Dan College for educational administration management system and synthesizing the design and development ideas of similar systems at home and abroad, we have designed and developed this set of educational administration management system of Geng Dan College. In the process of system construction, we have carried out a variety of software engineering methods, based on WBS, we have successfully realized the project task decomposition and planning, and successfully ensured the development progress of the main functions of the project through the critical path method. A cost management plan is developed to ensure the successful development of the project within the budget. The table partitioning and indexing technology based on Oracle successfully solves the bottleneck problem of high concurrency access in the system. The peak value of the test system can achieve more than 500 concurrent access support. The research of intelligent course scheduling algorithm based on genetic algorithm is realized, which can reduce the problem of excessive manual intervention in the current domestic similar system. In the aspect of system architecture, the application of database cluster technology based on Oracle RAC is successfully realized, and the requirements of data integrity, accuracy and availability are ensured successfully. In addition, since the system ultimately supports access to the public network, all the system security methods are successfully applied to ensure the security of the system.
