B Trees are used for indexing in databases and file systems.
Used for efficient searching, insertion, and deletion operations in databases.
Helps in maintaining sorted data for quick retrieval.

Each node in a B Tree can have multiple children, reducing the height of the tree.
CTE stands for Common Table Expression in SQL, used to create temporary result sets that can be referenced within a SELECT, INSERT, UPDATE, or DELETE statement.
CTEs improve readability and maintainability of complex queries
CTEs can be recursive, allowing for hierarchical data querying
CTEs are defined using the WITH keyword followed by the CTE name and query

Arrow functions are a concise way to write functions in JavaScript.
Arrow functions have a shorter syntax compared to regular functions.
They do not have their own 'this' keyword, and instead inherit 'this' from the parent scope.
Arrow functions are best suited for non-method functions, and cannot be used as constructors.
Example: const add = (a, b) => a + b;

Runtime polymorphism is achieved through method overriding in object-oriented programming.
It allows a subclass to provide a specific implementation of a method that is already defined in its superclass.
The actual method called is determined by the type of object at runtime.
Example: Animal class has a method 'makeSo...
Abstraction in OOP is the concept of hiding complex implementation details and showing only the necessary features to the outside world.
Abstraction allows us to focus on what an object does rather than how it does it
It helps in reducing complexity and improving maintainability of code
Example: A car is an abstraction of various components like engine, wheels, etc. Users interact with the car without needing to know the
