Mainly there are four concepts for OOAD.
1.Abstraction -grouping of data and behaviour(operations)
into a conceptual object.
2.Encapsulation -Its the implementation mode of data
abstraction.With encapsulation, we can accomplish data
hiding
3.Polymorphism -Polymorphism refers to the process whereby
an object invokes a method of another object in a common
manner (with the same name) without understanding or caring
how it is accomplished.
4.Inheritance-When an object is derived from another
object. It inherits all the properties etc
