摘 要 是以提供信息服务为主要目的的数据密集型、的应用系统。信息管理是指在整个管理过程中，人们收集、加工和输入、输出的信息的总称。作为计算机应用的一部分,使用计算机对学校的各类信息进行管理具有着手工管理所无法比拟的优点例如:检索迅速、查询方便、效率高、可靠性好、存储量大、必威体育官网网址性好、寿命长、成本低等。这些优点能够极大地提高学校信息管理的效率也是一个单位科学化、正规化管理与世界接轨的重要条件。随着我校办学规模的不断扩大，按照传统的人工方式进行教学管理，由于业务量大，以及人为主观因素的影响，已难以适应新形势的需要，不便于工作的顺利开展。为了加强管理，减轻工作人员的负担，提高工作效率，设计出一套实用性较强的教学管理系统。为用户提供丰富的信息、快捷的查询手段。使用户摆脱人工操作的工作模式，实现教学信息管理的科学化、现代化。Oracle数据库，建立一个具有一定的安全性和完整性控制的教学信息系统，支持SQL查询。 关键词： Abstract Information System is to provide information services for the primary purpose of data-intensive, interactive computer applications. The information management is refers in the entire management process, the people collect, the processing and the input, the output information always called.The school administration information system is in the usual significance computer management information system in the education domain concrete utilization.In recent years, the management information system the theory and the practice development is extremely rapid, the management information system the research more and more to appear in the modern management importantly.As a computer application part, uses the computer to carry on the management for school each kind of information, is having the merit which the manual administration center is unable to compare. For example: Retrieves, the inquiry rapidly convenient, the efficiency high, the reliability good, the reserves big, the secrecy good, the life long, the cost low status.These merits can enhance the school information management enormously the efficiency, also is a unit scientific style, the standardized management, with world trail connection important condition. The goal accelerates along with the national economy to develop, my school scale of study programs unceasing expansion, carries on the teaching management according to the traditional artificial way, because the business volume is big, as well as the artificial subjective factor influence, met the new situation need with difficulty, is not adv
