What is the difference between software development and system development (program development and software development areaNot)

1. Mobile phone system development generally refers to the development of apps. System development includes software system development and hardware system development. The range is relatively large. Software development is the process of building a software system or a software part of the system according to user requirements.

2. The differences between software development and programming are as follows: software development refers to the development of a software project, such as market research, demand analysis, researchable analysis, preliminary design, detailed design, document formation, preliminary model establishment, detailed code writing, test modification, release, etc.

3. The content is different. The specification specification mainly describes the functions that the software system should complete, including hardware, functions, performance, input and output, interface requirements, warning information, confidentiality and security, data and database, documents and regulations, etc.The design manual explains how to realize these functions and performance.

4. The differences between systems and software include differences in definition, differences in characteristics and differences in functions. Defined different system software refers to a system that controls and coordinates computers and external devices, and supports application software development and operation. It is a collection of various programs that do not require user intervention.

5. Different types of platform development. Embedded system development is the development of operating systems on all electronic devices except computers. The development objects include mobile phones, handheld computers, electromechanical systems, etc., generally composed of embedded microprocessors, peripheral hardware equipment, embedded operating systems and users' It is composed of four parts such as programs.

softWhat are the steps of system development?

1. Software development is generally divided into five stages: problem definition and planning. This stage is a joint discussion between software development and requirements, mainly to determine the development goals of the software and its feasibility. Requirements analysis conducts detailed requirements analysis of each function that the software needs to be realized under the condition of determining the feasibility of software development.

2. The main steps of software development are: project analysis, development determination, requirements analysis, design, programming, software testing, software delivery, acceptance and maintenance. The specific steps are as follows: the first process of software development is the analysis and determination of project development.

3. 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.

4. Steps: Demand analysis: Demand analysis is divided into three types: business requirements, user requirements and functional requirements. Business requirements: It reflects the high-level purpose requirements of organizations or customers for systems and products, and they are explained in project views and scope documents.

Five stages of software development

1. Software development is generally divided into five stages: problem definition and planning. This stage is a joint discussion between software development and requirements, mainly to determine the development goals of the software and its feasibility. Requirements analysis Under the condition of determining the feasibility of software development, conduct a detailed requirement analysis of each function that the software needs to be realized.

2. Software development is generally divided into 5 stages, namely: problem definition and planning, requirements analysis, software design, program coding, and software testing.

3. The software life cycle is divided into five stages: problem definition, feasibility study, requirements analysis, development stage and maintenance. The main tasks of each stage are as follows.

4. Software development generally has five stages, namely problem definition and planning, requirements analysis, software design, program coding and software testing. Software development is the process of building a software system or a software part of the system according to user requirements.
