SQL stands for structured query language. This language is a domain specific language that you are going to use if you are programming or trying to manage data inside of a RDBMS (relational database management system). SQL is a language that is designed to work with databases. What are databases? Well, they're a collection of data that's organized into a semi-recognizable shape. But what good does that data do if you have to sort through it every time that you need to access data? That's what SQL does. It helps you to manage and sort data with minimal effort.

SQL was started with math, both tuple relational calculus and relational algebra. There is a lot of data definitions and manipulations along with control language that is going to be inside of SQL. SQL involves the use of things such as delete, update, insert, and query.

Please do not assume that this is a comprehensive guide to SQL - it isn't. It is purely a basis, something for you to understand and build on. With this guide, you can learn the basics of SQL inside of 1 day, sufficient to do your job easily while you move on to more advanced concepts.Are you eager to understand the dynamics of SQL?
