The document discusses the object oriented programming (OOP) paradigm. It describes OOP as a programming paradigm based on objects that contain both data and methods. Objects interact and work together to design applications. The document traces the history and development of OOP, including early languages like Simula and Smalltalk. It notes that OOP provides benefits like modularity and reusability. The OOP paradigm became widely used with languages in the 1990s and remains an important methodology for software development.

• 2.1 Introduction to OO Paradigm
• Object-oriented programming (OOP) is a programming paradigm
based upon objects (having both data and methods) that aims to
incorporate the advantages of modularity and reusability.
• Objects, which are usually instances of classes, are used to interact
with one another to design applications and computer programs.

5. What is meant by an OOP Paradigm?
• OOP is a programming paradigm
based on the concept of "objects",
which can contain data and code:
data in the form of fields, and code,
in the form of procedures. A
common feature of objects is that
procedures are attached to them
and can access and modify the
object's data fields.

6. OOP Paradigm
• OOP is shape from the initial concept of a new programming
approach, while the interest in design and analysis methods came
much later.
• OO analysis and design paradigm is the logical result of the wide
adoption of OO programming languages.
• The first object–oriented language was Simula (Simulation of real
systems) that was developed in 1960 by researchers at the
Norwegian Computing Center.

7. OOP Paradigm
• In 1970, Alan Kay and his research group at Xerox PARC created a
personal computer named Dynabook and the first pure object-
oriented programming language (OOPL) - Smalltalk, for
programming the Dynabook.
•
• In the 1980s, Grady Booch published a paper titled Object
Oriented Design that mainly presented a design for the
programming language, Ada. In the ensuing editions, he extended
his ideas to a complete object–oriented design method.

8. OOP Paradigm
• In the 1990s, Coad incorporated behavioral ideas to object-
oriented methods.
• The other significant innovations were Object Modeling
Techniques (OMT) by James Rum Baugh and Object-Oriented
Software Engineering (OOSE) by Ivar Jacobson.
• OO paradigm is a significant methodology for the development of
any software.
• Most of the architecture styles or patterns such as pipe and filter,
data repository, and component-based can be implemented by
using this paradigm.
