What is OO (Object Orientation)? </h2>
<ul style="text-align: left;">
<li>A technique for system modeling</li>
<li>OO model consists of several interacting objects</li>
</ul>
<h3 style="text-align: left;">
 What is Model? </h3>
<div style="text-align: left;">
</div>
<ul style="text-align: left;">
<li>A model is an abstraction of something </li>
<li>Purpose is to understand the product before developing it</li>
</ul>
Examples could be <br />
<ul style="text-align: left;">
<li>Architectural models </li>
<li>Mechanical models </li>
</ul>
<div style="text-align: left;">
</div>
<h3 style="text-align: left;">
What is Object? </h3>
<div style="text-align: left;">
</div>
<ul style="text-align: left;">
<li>Something Tangible (Danish, Car, House) </li>
<li>Something that can be detained intellectually (Time, Date) </li>
</ul>
An object has <br />
<ul style="text-align: left;"><ul>
<li>State (attributes) </li>
<li>Well-defined behavior (operations) </li>
<li>Unique identity </li>
</ul>
</ul>
Example: Danish is Tangible Object <br />
<ul style="text-align: left;">
<li>State (attributes) </li>
<ul>
<li>Name </li>
<li>Age </li>
</ul>
<li>Behavior (operations) </li>
<ul>
<li>Walks </li>
<li>Eats </li>
</ul>
<li>Identity </li>
<ul>
<li>His name </li>
</ul>
</ul>
<div style="text-align: left;">
<br />
In pure OOP terms, an object is an instance of a class (A class is simply a representation of a type of object) <br />

What is Object Orientation Programming? </h2>
<div style="text-align: left;">
Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects", which are data structures that contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. A distinguishing feature of objects is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this" or "self"). In OO programming, computer programs are designed by making them out of objects that interact with one another. There is significant diversity in object-oriented programming, but most popular languages are class-based, meaning that objects are instances of classes, which typically also determines their type.

<b>In OOP </b></div>
<ul style="text-align: left;">
<li>Information is stored within the object </li>
<li>It is hidden from the outside world </li>
<li>It can only be manipulated by the object itself </li>
</ul>
<div style="text-align: left;">
<br />
<b>For example </b></div>
<ul style="text-align: left;">
<li>Ali’s name is stored within his brain </li>
<li>We can’t access his name directly </li>
<li>Rather we can ask him to tell his name </li>
<li>A phone stores several phone numbers </li>
<li>We can’t read the numbers directly from the SIM card </li>
<li>Rather phone-set reads this information for us</li>
</ul>
