Development, advantages and disadvantages of management information system

Development, advantages and disadvantages of management information system? Structured system development method (SSA&; D) Advantages: the development stages are strictly distinguished, and the system has strong pertinence; Good integrity and overall awareness, top-down view; Disadvantages: long development cycle; The development process is complicated; Backward development tools; Communication with users is not intuitive; It is difficult to upgrade the system. Advantages of prototype method: 1, which conforms to the law of people's understanding of things; 2. Some potential problems after the implementation of the system can be exposed as soon as possible; 3, can mobilize the enthusiasm of users to participate. Disadvantages: 1, not suitable for the development of large-scale systems; 2, not suitable for a large number of operations and logic modules; 3. Higher requirements for the basic management of the original enterprise; Otherwise, it is easy to embark on the track of mechanical simulation of the original manual system. The characteristics of object-oriented development method: encapsulation; Abstract; Inherit; Dynamic linkage;
