t. e. 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 ...
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 ...
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 ...
System Safety is the overarching discipline that aims to achieve safety by reducing risks in technical systems to an acceptable level. According to the widely adopted system safety standard IEC 61508, [ 1] safety is “freedom from unacceptable risk of harm”. As software alone – which can be considered as pure information – cannot cause ...
Don't repeat yourself. " Don't repeat yourself " ( DRY) is a principle of software development aimed at reducing repetition of information which is likely to change, replacing it with abstractions that are less likely to change, or using data normalization which avoids redundancy in the first place. The DRY principle is stated as "Every piece ...
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 ...
One way to prevent individual engineers or teams from circumventing the pipeline is to require the same approach for everyone, but in a way that doesn’t slow the teams down. “If you build a ...
Software architecture description is the set of practices for expressing, communicating and analysing software architectures (also called architectural rendering), and the result of applying such practices through a work product expressing a software architecture ( ISO/IEC/IEEE 42010 ). Architecture descriptions (ADs) are also sometimes ...
