Draw and Explain the Software Engineering Layers
Software Engineering Layers:
Software Engineering is a layered technology. It is the application of principles uses in the field of engineering, which usually deals with physical systems, to the design, development, testing, deployment and management of systems.
The main objective of software engineering layers is to help software developers obtain high-quality software. There are four types of layers in Software Engineering such as – Tools, methods, process, A quality focus.
i. A quality focus:
It is a culture that ultimately leads to the development of software engineering. The bedrock that supports software engineering, it says A quality focus
ii. Process: According to Ivar Jacobson, A process defines who is doing what, when and how to reach a certain goal. The software process forms the basis for management control of software projects. It establishes the context in which technical methods are applied for work products are produced.
Example: Models, Documents, Data, Reports, Forms, etc.
iii. Methods: Software Engineering methods provide the technical “how to’s for building software“. Methods encompass a broad array of tasks that include communication, requirements analysis, design modelling, program construction, testing and support.
iv. Tools: Software Engineering tools provide automated or semi-automated support for the process and the methods. When tools are integrated so that information created by one tool can be used by another, a system for the support of software development is called Computer-Aided Software Engineering.
