Object-Oriented Programming: Data
built 807 days ago
Both object-oriented programming and relational database management systems (RDBMSs) are extremely common in software today. Since relational databases don't store objects directly (though some RDBMSs have object-oriented features to approximate this), there is a general need to bridge the two worlds. There are a number of widely used solutions to this problem. One of the most common is object-relational mapping, as found in libraries like Java Data Objects, and Ruby on Rails' ActiveRecord.

Object-oriented programming, as typified by the Small-talk model, views the programming task as dealing with objects which interact by sending messages to each other. Concurrency is not necessarily implied by this model and destructive assignment is provided. In particular, to the notion of an abstract data type, OOP adds the notion of inheritance, a hierarchy of relationships among types. The idea of data is generalized from simple items in a domain to data type (a domain and associated operations) to an abstract data type (the addition of information hiding) to OOP & inheritance.

Object-oriented programming or OOP is a paradigm of computer science. A computer program is made of a collection of objects, that call each other. In the traditional view, a program used to call functions that act on some set of data. With the object-oriented view, the set of data that is acted upon is implicit (the object itself).

Object-oriented programming may be seen as a collection of cooperating objects, as opposed to a traditional view in which a program may be seen as a list of instructions to the computer. In OOP, each object is capable of receiving messages, processing data, and sending messages to other objects. Each object can be viewed as an independent little machine with a distinct role or responsibility.[2]

Object-oriented programming (OOP) is based on the idea that real-world entities or relationships can be represented in code as objects. These code objects have associated with them data and behave in certain ways when asked to. Objects can be linked together to form programs and applications.
