基于负载均衡的在线选课系统的研究与实现 摘要:随着我国高等教育体制大规模的改革,院校合并、校区分散、专业设置日趋多样化,招生人数逐年增加,学年制逐步改为学分制,这使得高校教学管理的工作量大幅度增加。学生的选课工作是高校教学管理的重要组成部分,传统的人工选课模式已难以适应信息化、现代化的要求,因此,各高校为了提高办公效率,提高教学的灵活性,都在开发适合自身需求的选课系统。 临沂大学沂水分校现有在校生近4000人,专业门类多,课程设置复杂,师资力量、教学资源相对紧张,教学管理正在逐步由学年制向学分制转变,原有的选课操作一直由教务管理人员人工完成,工作量非常大,数据繁琐,而且还容易出现人为的错误,一旦处理失误将会造成教学资源的浪费,严重地甚至会导致教学事故。所以充分利用校园网络平台,设计开发在线选课系统已是当务之急。 本论文研究的目的在于设计开发基于ASP.NETWith the large-scale reform of Chinas higher education system, institutions merge, decentralized campus, professional settings is becoming more diverse, year by year increase in enrollment, the academic year and gradually changed to the credit system, which makes teaching management in a substantial increase in the workload. The students course selection is an important part of teaching management, the traditional artificial elective mode has been difficult to adapt to information technology, modern requirements, and therefore, all colleges and universities in order to improve office efficiency and improve the flexibility of teaching in the development suited to their own demand for Course Selection System. Lin Yi University Yishui College has nearly 4,000 people, many professional categories, the complexity of the curriculum, faculty, teaching resources tense, teaching management is gradually shift to the credit system from the academic year, the original elective operations by the Senate management is done manually, the workload is very large, cumbersome data, but also prone to human error, once the processing errors will result in waste of teaching resources, serious and even lead to teaching accident. So take full advantage of the campus network platform, the online course selection system design and development is a priority. The purpose of this thesis is the design and development based on ASP.NET programming techniques, while using load balancing and server allocation management to solve the problem of network congestion due to the to elective peak of the design into a set of infor
