AOP concepts
In this section, we will look at what problems we have to face if we use only the object-oriented programming (OOP) paradigm. Then we will understand how AOP solves those problems. We will walk through the concepts of AOP and ways to implement AOP concepts.
Limitations of OOP
With the help of OOP fundamentals and design patterns, application development was divided into groups of functionalities. OOP protocols made many things easy and useful, such as introducing an interface with which we can implement loosely-coupled designs, encapsulation with which we can hide object data, and inheritance-extending functionalities, by classes, with which we can reuse work.
These advantages of OOP also add complexity as the system grows. With added complexities, the cost to maintain it and the chances of failure increase. To solve this, modularizing functionalities into simpler and more manageable modules helps reduce complexity.
To modularize a system, we started following a practice of dividing...
