In software programming, SOLID is a mnemonic acronym for five design principles intended to make object-oriented designs more understandable, flexible, and maintainable. Although the SOLID principles apply to any object-oriented design, they can also form a core philosophy for methodologies such as agile development or adaptive software ...
Larman states that "the critical design tool for software development is a mind well educated in design principles. It is not UML or any other technology." [ 3 ] : 272 Thus, the GRASP principles are really a mental toolset, a learning aid to help in the design of object-oriented software.
SOLID is a set of five rules for designing good software, created by Michael Feathers: Single responsibility principle: A class should have only one reason to change. Open/closed principle: Software entities should be open for extension, but closed for modification.
In object-oriented programming, the open–closed principle (OCP) states "software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification"; [1] that is, such an entity can allow its behaviour to be extended without modifying its source code.
Having a solid balance of electrolytes helps to regulate fluids and pH levels, support muscle and nerve function, and promote brain health, says Dr. Alex Crane, a primary care doctor with Scripps ...
Diagram illustrating the principle of separation of concerns, which says that an action entity can only contain a single type of tasks. In computer science, separation of concerns (sometimes abbreviated as SoC) is a design principle for separating a computer program into distinct sections.
ISP is one of the five SOLID principles of object-oriented design, similar to the High Cohesion Principle of GRASP. [3] Beyond object-oriented design, ISP is also a key principle in the design of distributed systems in general and one of the six IDEALS principles for microservice design. [4]
Liskov's notion of a behavioural subtype defines a notion of substitutability for objects; that is, if S is a subtype of T, then objects of type T in a program may be replaced with objects of type S without altering any of the desirable properties of that program (e.g. correctness).
