In general, the management of information systems and applications can be divided into the overall planning, system development and system operation in three stages, which can be further divided into the system development phase of system analysis, system design and system implementation and other work areas. The various stages of development arranged in a strict linear sequence, at every stage of complete technical documentation produced as the next phase of the guidance and the basis for each stage of the document should be reviewed, make sure that the stage has been completed and meet the requirements before entering the next stage, while the later work can not be easily changed after the previous assessment results.
The main advantage of this development approach is to facilitate the development of the organization and management, and management information systems can greatly reduce the development complexity. Many examples of systems development at home and abroad have shown that this is an effective development approach.〖资料来源:计算机毕业论文 www.xiaoniu168.com〗
