Subroutine

functionfunctionssubroutines
In computer science, an object can be a variable, a data structure, a function, or a method, and as such, is a value in memory referenced by an identifier.
The discipline of object-oriented programming is based on objects and methods (which are subroutines attached to these objects or object classes).

Method (computer programming)

methodsmethodabstract method
In computer science, an object can be a variable, a data structure, a function, or a method, and as such, is a value in memory referenced by an identifier.
A method in object-oriented programming (OOP) is a procedure associated with a message and an object.

Object-oriented programming

object-orientedobject orientedobject-oriented programming language
In the class-based object-oriented programming paradigm, object refers to a particular instance of a class, where the object can be a combination of variables, functions, and data structures.
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which can contain data, in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods).

Class-based programming

class-basedclass definedclass-based inheritance
In the class-based object-oriented programming paradigm, object refers to a particular instance of a class, where the object can be a combination of variables, functions, and data structures.
Class-based programming, or more commonly class-orientation, is a style of Object-oriented programming (OOP) in which inheritance occurs via defining classes of objects, instead of inheritance occurring via the objects alone (compare prototype-based programming).

Class (computer programming)

classclassesPartial class
In the class-based object-oriented programming paradigm, object refers to a particular instance of a class, where the object can be a combination of variables, functions, and data structures.
In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods).

Instance (computer science)

instanceinstancesinstantiated
In the class-based object-oriented programming paradigm, object refers to a particular instance of a class, where the object can be a combination of variables, functions, and data structures.
In object-oriented programming (OOP), an instance is a concrete occurrence of any object, existing usually during the runtime of a computer program.

Data structure

In computer science, an object can be a variable, a data structure, a function, or a method, and as such, is a value in memory referenced by an identifier.

Inheritance (object-oriented programming)

inheritancesuperclasssubclass
An object is an abstract data type with the addition of polymorphism and inheritance.
In object-oriented programming, inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation.

Function object

functorfunction objectsfunctors
In computer programming, a function object is a construct allowing an object to be invoked or called as if it were an ordinary function, usually with the same syntax (a function parameter that can also be a function).

Software design pattern

design patterndesign patternspattern
An important concept for objects is the design pattern.
Object-oriented design patterns typically show relationships and interactions between classes or objects, without specifying the final application classes or objects that are involved.

Immutable object

In object-oriented and functional programming, an immutable object (unchangeable object) is an object whose state cannot be modified after it is created.

Database

database management systemdatabasesDBMS
In relational database management, an object can be a table or column, or an association between data and a database entity (such as relating a person's age to a specific person).
Programmers and designers began to treat the data in their databases as objects.

Factory (object-oriented programming)

factoryfactoriesFactory object
In object-oriented programming (OOP), a factory is an object for creating other objects – formally a factory is a function or method that returns objects of a varying prototype or class from some method call, which is assumed to be "new".

Metaobject

metaobject protocolmeta-object protocolmetaobject protocols
In computer science, a metaobject is an object that manipulates, creates, describes, or implements objects (including itself).

Variable (computer science)

variablevariablesscalar
In computer science, an object can be a variable, a data structure, a function, or a method, and as such, is a value in memory referenced by an identifier.
A value, however, is an abstraction, an idea; in implementation, a value is represented by some data object, which is stored somewhere in computer memory.

God object

In object-oriented programming, a God object is an object that knows too much or does too much.

Abstract data type

abstract data typesabstract data structureabstract
Object-orientation is simply the logical extension of older techniques such as structured programming and abstract data types.
In this model an ADT is typically implemented as a class, and each instance of the ADT is usually an object of that class.

Object copying

In object-oriented programming, object copying is creating a copy of an existing object, a unit of data in object-oriented programming.

OWL objects are not like standard large grained distributed objects accessed via an Interface Definition Language.
