Generic collections are type-safe and can store any type of data. Non-generic collections can only store objects of type 'object'.
Generic collections are preferred as they provide compile-time type safety.
Non-generic collections are slower and can cause runtime errors if the wrong type is added.
Examples of generic collections include List
Examples of non-generic collections include
Triggers are database objects that automatically execute in response to certain events.
Triggers can be used to enforce business rules or perform complex calculations.
Types of triggers include DML triggers, DDL triggers, and logon triggers.
DML triggers fire in response to data manipulation language (DML) events, such as INSERT, UPDATE, or DELETE statements.
DDL triggers fire in response to data definition language (DDL) ...

Stack using queues: push() - enqueue to queue1, pop() - dequeue from queue2 after transferring n-1 elements from queue1 to queue2
To push an element, enqueue it to queue1
To pop an element, transfer n-1 elements from queue1 to queue2, dequeue the last element from queue1 and swap the names of queue1 and queue2

A program to find factorial using recursion.
Define a function that takes an integer as input.
Check if the input is 0 or 1, return 1 in that case.
Otherwise, call the function recursively with input-1 and multiply it with the input.
Indexes are data structures that improve the speed of data retrieval operations in a database. Views are virtual tables created from queries.
Indexes are used to quickly locate data in a database by creating a sorted structure that allows for efficient searching.
Views are virtual tables that are created by executing a query and storing the result set as a named object.
Indexes can be created on one or more columns of a t...
Indexes are implemented using B Trees and B+ Trees.
B Trees and B+ Trees are data structures used to organize and efficiently search data in databases.
B Trees are balanced search trees that store data in nodes with multiple children.
B+ Trees are similar to B Trees but have additional features like leaf nodes that form a linked list.
Indexes are created on specific columns of a database table to improve query performance.
...
Other than indexes and tables, a DBMS also includes views, stored procedures, triggers, and functions.
Views: Virtual tables that are based on the result of a query. They provide a way to simplify complex queries and restrict access to data.
Stored Procedures: Precompiled sets of SQL statements that can be executed with a single command. They enhance performance and allow for code reusability.
Triggers: Special types of s...

Types of integrity in DBMS include foreign, referential, and domain.
Foreign integrity ensures that foreign key values in a table match primary key values in another table.
Referential integrity ensures that relationships between tables are maintained, preventing orphaned or invalid data.
Domain integrity ensures that data in a column adheres to specified data types, formats, or constraints.
For example, in a database for ...

Encapsulation, data abstraction, and polymorphism are three fundamental concepts in object-oriented programming.
Encapsulation is the process of hiding the implementation details of an object from the outside world.
Data abstraction is the process of representing only the essential features of an object and hiding the unnecessary details.
Polymorphism is the ability of an object to take on many forms or have multiple beha...
Stack is a data structure that follows Last In First Out (LIFO) principle. Queue is a data structure that follows First In First Out (FIFO) principle.
Stack is like a stack of plates where the last plate added is the first one to be removed
Queue is like a queue of people waiting in line where the first person added is the first one to be served
Stack operations: push (add element), pop (remove top element), peek (get top...
Caching is the process of storing frequently used data in a temporary storage area for faster access.
Caching improves application performance by reducing the number of requests to the server.
It can be implemented at different levels such as browser, server, and database.
Examples of caching include browser caching of web pages, server caching of API responses, and database caching of query results.
Join types used in SQL to combine data from multiple tables.
Inner join returns only the matching rows from both tables.
Left join returns all rows from the left table and matching rows from the right table.
Outer join returns all rows from both tables, with null values for non-matching rows.
Examples: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.id
SELECT * FROM table1 LEFT JOIN table2 ON table1.id = table2...
