In many programming languages, object is a generic data type. It either exists high-up, possibly at the top of, the class hierarchy, and/or is the non-primitive base type.
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.
In the class-based object-oriented programming paradigm,
objectrefers to a particular instance of a class, where the object can be a combination of variables, functions, and data structures.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).
