SQL Short Notes
SQL is a language that lets you talk to databases and ask them questions. You can use SQL to store, retrieve, and manipulate data in tables. SQL is very useful for working with data, whether it is for analysis, reporting, or development. However, SQL can also be hard to learn, especially if you are not familiar with the terms and concepts of databases. Thatโs why I have created these SQL short notes in simple style in PDF format, which explain the basics of SQL in a simple and easy way.
These notes are based on my own experience and knowledge of SQL, as well as the official documentation and online resources. They are not meant to be a complete guide or a replacement for a textbook, but rather a quick reference and a learning tool for anyone who wants to learn SQL.
