EVOLUTION OF THE POO AND THE MODERN PROGRAMMING

EVOLUTION OF THE POO AND THE MODERN PROGRAMMING

1. Object-oriented programming is a philosophy of implementation where the programs are organized as a cooperative collection of objects, each of which represents an instance of a class and whose classes belong to a hierarchy of classes United through an inheritance relationship.

2. FUNDAMENTAL CONCEPTS OF OOP

   • CLASS
     • Instantiation is reading these definitions and the creation of an object to starting from these class represents the essence of the object and the object is an entity that It exists in time and space.
   • HERITAGE
     • With the inheritance type hierarchies are established "is a", in where a subclass inherits structure and behavior of one or more superclasses more generalized.
   • OBJECT
     • Entity provided with a set of properties or attributes (data) and behavioral or functionality (methods) which consequently react to events.
   • METHOD
     • A method can produce a change in the properties of the object, or the generation of an "event" with a new message to another object on the system.
   • EVENT
     • Es un suceso en el sistema (tal como una interacción del usuario con la máquina, o un mensaje enviado por un objeto).
   • PROPERTY OR ATTRIBUTE
     • Container of a type of data associated with an object (or to a class of objects), which makes the data visible from outside of the object and this is defined as its characteristics default
   • IDENTIFICATION OF AN OBJECT
     • An object is represented by a table, or entity that is made up of its attributes and corresponding functions.
