OOPs stands for Object-Oriented Programming and SQL stands for Structured Query Language.

• OOPs is a programming paradigm based on the concept of objects, which can contain data in the form of fields and code in the form of procedures.

• SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS).

The basic pillars of OOPs are Inheritance, Encapsulation, Polymorphism, and Abstraction.

• Inheritance: Allows a class to inherit properties and behavior from another class.

• Encapsulation: Bundling data and methods that operate on the data into a single unit.

• Polymorphism: Ability to present the same interface for different data types.

• Abstraction: Hiding the complex implementation details and showing only the necessary features.
