Exploring SQL, NoSQL Databases, and MongoDB: A Comprehensive Guide

Exploring SQL, NoSQL Databases, and MongoDB: A Comprehensive Guide

Databases serve as organized collections of data, allowing efficient storage, retrieval, and manipulation of information. They are essential for managing data in various applications, ranging from small-scale projects to large enterprise systems. Two primary categories of databases exist: SQL (relational) and NoSQL (non-relational). SQL and NoSQL Databases SQL databases, or relational databases, adhere to the Structured Query Language (SQL) standard for defining, querying, and manipulating data. They use a tabular schema with predefined relationships between tables. Examples include MySQL, PostgreSQL,…
