Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations. [ 1][ 2] The architecture of a software system is a metaphor, analogous to the ...
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
In software engineering, a design pattern describes a relatively small, well-defined aspect (i.e. functionality) of a computer program in terms of how to write the code . Using a pattern is intended to leverage an existing concept rather than re-inventing it. This can decrease the time to develop software and increase the quality of the ...
Conway's law. Conway's law describes the link between communication structure of organizations and the systems they design. It is named after the computer programmer Melvin Conway, who introduced the idea in 1967. [ 1] His original wording was: [ 2][ 3] [O]rganizations which design systems (in the broad sense used here) are constrained to ...
v. t. e. TestingCup – Polish Championship in Software Testing, Katowice, May 2016. Software testing is the act of checking whether software satisfies expectations. Software testing can provide objective, independent information about the quality of software and the risk of its failure to a user or sponsor. [ 1] Software testing can determine ...
In the early 1970s, companies began to separate out software maintenance with its own team of engineers to free up software development teams from support tasks. [1] In 1972, R. G. Canning published "The Maintenance 'Iceberg '", in which he contended that software maintenance was an extension of software development with an additional input: the existing system. [1]
The company has suffered a steep hit to its reputation, and the stock price plunged from $345.10 on Thursday evening to $263.10 by Monday afternoon. It has since recovered slightly. In a statement ...
A software system consists of several separate computer programs and associated configuration files, documentation, etc., that operate together. [1] The concept is used in the study of large and complex software, because it focuses on the major components of software and their interactions. It is also related to the field of software architecture .
