The overall design of software engineering includes: computer configuration design, system module structure design, database and file design, code design, system reliability and internal control design, etc.[2]The software function decomposition belongs to the overall design stage of the following software development.
Complete the design process of overall scheme and overall technical approach of large-scale engineering system.In generalengineering designMedium overall design refers to the general calculation according to the content of the plan assignment, with necessary text description and drawing design, also known as preliminary design.aboutEngineering system engineeringOverall design refers to the former meaning.The overall design is an important stage in the project development process (see figure).
The basic problem of developing a large-scale engineering system is how to gradually transform the general initial development requirements into the specific work of thousands of research participants, and how to finally integrate these work into a practical system that is technologically advanced, economically cost-effective, has a short development cycle, and can operate in coordination,And make this system an effective part of the larger system to which it belongs.In 1954, Ramo Waldridge, a system engineering company, first appeared in the United States to provide such services for missile development plans.In the late 1950s, when China began to develop artificial satellites and launch vehicles, it also established such an organization and called it the Overall Design Department.The Overall Design Department designs the overall system, the overall scheme of the system and the technical approach to realize it, and passes the feasibility study andTechnical and economic demonstrationTo ensure that the overall performance of the project is optimal in all stages of planning, design, manufacturing and operation.This can avoid the waste of human, material and financial resources due to the defects of planning, development and application.
