Q6. Like what is oops, sql
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).
Q7. Basic pillars of oops
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.
Q8. Types of joins in SQL
Types of joins in SQL include inner join, outer join (left, right, full), cross join, and self join.
Inner join: returns rows when there is a match in both tables
Outer join: returns all rows from one table and only matching rows from the other table
Cross join: returns the Cartesian product of the two tables
Self join: joins a table to itself
