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. That’s 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.
