Introduction to SQL: Understanding the Basics

SQL (Structured Query Language) is a powerful language used to interact with Database Management Systems (DBMS). It is specifically designed for querying and manipulating data in relational databases. In this blog post, we will explore the fundamental concepts of SQL and gain insights into its evolution and implementations.

The Evolution of SQL

First published in 1986, SQL has undergone several updates and revisions over the years. The latest version, as of writing this blog, is SQL 2019. This continuous evolution reflects the growing demands and advancements in database technology. While different implementations of SQL exist, we will primarily focus on the SQL standard and its core features.

Understanding SQL Implementations

SQL is supported by numerous popular DBMS, such as PostgreSQL, MySQL, Oracle, SQLite, and Microsoft SQL Server, among others. Each DBMS implements the SQL standard while also offering additional features and functionalities. These custom features are intended to simplify the creation of queries or add specific capabilities to the database.
