Proponents of object-oriented techniques point to the flexibility and extensibility of object-oriented systems along with other benefits such as increased modularity, abstraction, and encapsulation.

These are terms that are used to indicate the qualitative analysis of the modularity in a system, and they help us to identify and measure the design complexity of object oriented systems.

Object-oriented programming allows procedures about objects to be created whose exact type is not known until runtime. For example, a screen cursor may change its shape from an arrow to a line ...

Aspect-oriented programming allows you to isolate the cross-cutting concerns of your application, reduce code duplication, and improve the readability and maintainability of your code.
