One component of software design is software requirements analysis (SRA). SRA is a part of the software development process that lists specifications used in software engineering. The output of the analysis is smaller problems to solve. In contrast, the design focuses on capabilities, and thus multiple designs for the same problem can exist.
Software engineering is a field within computer science focused on designing, developing, testing, and maintaining of software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
These are sometimes named architecture characteristics, or "ilities" after the suffix many of the words share. They are usually architecturally significant requirements that require architects' attention. [1] In software architecture, these attributed are known as "architectural characteristic" or non-functional requirements.
In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure that can be transplanted directly into source code. Rather, it is a description or a template for solving a particular type of ...
In the context of software engineering, software quality refers to two related but distinct notions: [citation needed] Software's functional quality reflects how well it complies with or conforms to a given design, based on functional requirements or specifications. [ 1 ]
In engineering, a requirement is a condition that must be satisfied for the output of a work effort to be acceptable. It is an explicit, objective, clear and often quantitative description of a condition to be satisfied by a material, design, product, or service.
Whilst application design focuses on the design of the processes and data supporting the required functionality (the services offered by the system), software architecture design focuses on designing the infrastructure within which application functionality can be realized and executed such that the functionality is provided in a way which ...
The software quality metrics of coupling and cohesion were invented by Larry Constantine in the late 1960s as part of a structured design, based on characteristics of “good” programming practices that reduced maintenance and modification costs.
