The system development process is divided into requirements analysis-outline design-detailed design-coding-system testing-system delivery- - User acceptance - System analysts related to maintenance demand analysis have a preliminary understanding of the needs of users.
The first process of software development is the analysis and determination of project development. The main reason is that after the project development determined by the software developer, it is necessary to discuss with the demand side to determine the goals and specific requirements of the demand side software development. Next is the demand analysis. This step is also the stage to determine the specific ideas for the normal implementation of software development.
Software design stage Software design is to design the entire software system according to the results of requirements analysis. Including system framework design, database design, etc., which are divided into overall design and detailed design. Software design also lays a good foundation for software programming.
Application software package method: by purchasing commercialized software packages and basically developing the system here. It consists of 4 stages: system analysis-system design-system modification-system maintenance End-user method: users use development tools to develop various systems they need.
Structured life cycle method This method regards system development as an engineering project and works in a planned and step-by-step manner, although variousThe specific content of business information system processing is different, but all system development can be divided into six stages.
The main development methods of information systems include structured methods, prototype methods, enterprise system planning methods, strategic data planning methods, information engineering methods and object-oriented methods. Structured method Structured method is an information system development method composed of structured system analysis and design.
It is not suitable for the development of large-scale systems; it is not suitable for a large number of calculations and logical modules; it has high requirements for the basic management of the original enterprise, otherwise it is easy to get on the track of mechanical simulation of the original manual system.
. The operation and maintenance stage of the information system. When the information system passes the acceptance and is officially handed over to the user, the system enters the operation stage.
1. After the software design is completed, the software test should be rigorously tested to find problems in the whole software design process and correct them. The whole test stage is divided into three stages: unit test, assembly test and system test. The test methods mainly include white box test and black box test.
2. The general process of software development includes the following steps: requirements analysis: clarify the functional requirements, performance requirements, user interface requirements, etc. of the software system, and analyze and define. System design: Design the software system according to the results of requirements analysis, including database design, algorithm design, interface design, etc.
3. Software system development, information system development, application software system development, etc., which are developed by writing code.Software system refers to a computer software system composed of system software, supporting software and application software. It is a part of the computer system composed of software.
4. Eight steps of software development process: The first process of software development is the analysis and determination of project development. The main reason is that after the project development determined by the software developer, it is necessary to discuss with the demand side to determine the goals and specific requirements of the demand side software development. Next is the demand analysis.
5 、. The Global trade documentation templatesdevelopment process of NET self-service site construction system generally includes the following steps: requirements analysis: clarify customer needs, determine the functional modules of the system, user roles, data flow, technical selection, etc. Prototype design: Draw system prototypes according to the results of requirements analysis, including system page layout, interaction process, interface design, etc.
The four methods of information system development are structured method, prototype method, object-oriented method and service-oriented method. Structured method Structured method is a traditional software development method, which is an organic combination of three parts: structured analysis, structured design and structured programming.
Entrusted development method. The enterprise fully entrusts the development project to the development unit, and then delivers it to the enterprise for use after the system is completed. This way of entrusting the system integrator to undertake the task of development according to the needs of the user is called the entrusted development method. ( 3) Joint development method.
Object-oriented development method (1) Advantage analysis, consistency of objects in design and objects in software;Realize software reuse and simplify program design: the system is easy to maintain; shorten the development cycle.
Structured life cycle method. This method regards system development as an engineering project and works in a planned and step-by-step manner. Although the specific content of various business information system processing is different, all system development can be divided into six stages.
