Component-based software engineering (CBSE), also called component-based development (CBD), is a style of software engineering that aims to construct a software system from components that are loosely-coupled and reusable. This emphasizes the separation of concerns among components. [1] [2]
Component. is the abstraction for all components, including composite ones; declares the interface for objects in the composition (optional) defines an interface for accessing a component's parent in the recursive structure, and implements it if that's appropriate; Leaf. represents leaf objects in the composition; implements all Component ...
Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

Brad Cox refined the concept of a software component in the 1980s. [7] He attempted to create an infrastructure and market for reusable third-party components by inventing the Objective-C programming language. [8] IBM introduced System Object Model (SOM) in the early 1990s. [9] Microsoft introduced Component Object Model (COM) in the
For example, components can be seen as a mixin idiom in various programming languages. Components are a specialized case under the general delegation approach and meta-object protocol. That is, any complete component object system can be expressed with the templates and empathy model within The Orlando Treaty [2] vision of object-oriented ...
A component, in an object-oriented extent, represents a set of collaborative classes (or only one class) and its interfaces. The interfaces are responsible for enabling the replacement of components. Reusable components can also be isolated and synchronized between SCM repositories using component source code management technologies .
Component-oriented database (CODB) is a way of data administration and programming DBMS's using the paradigm of the component-orientation. [ citation needed ] Concepts
There is an extensive literature on formalized object models as a subset of the formal semantics of programming languages. A collection of objects or classes through which a program can examine and manipulate some specific parts of its world. In other words, the object-oriented interface to some service or system.
