SQL COMPUTER PROGRAMMING FOR BEGINNERS: LEARN THE BASICS OF SQL

Welcome! You got that promotion at work and you’ve been dropped in front of a computer and told to use SQL from now on. The problem is, you don’t know that much about SQL, let alone how to use it and if you don’t learn it quickly, you’re going to lose your promotion and find yourself, red-faced, right back where you started.
If you are interested in learning a new coding language, there are a lot of different options that you can choose from, and it really depends on what you are looking for and what you want to do with them. Some of these languages are good for helping you to create a good website. Some are better for beginners while others are good for those who are more advanced. Some are good for creating a smartphone application or for working on your own game to share with others.

You’ve come to the right place.
In this book, the following topics are going to be discussed:

The basics of SQL so you can do your job without the boss breathing down your neck
The use of non-technical approach to combat the nature of computer programming that is more of a technical language.
The aspects of a relational database
Introduction to databases and tables
How to make use of MySQL and the workbench
The data types you ought to know
The language of views, triggers, constraints and functions
Manipulating tables and how to combine/join them
How to normalize your database
Maintaining the security of your data
And many more!!
Don’t worry if you can’t keep up to start with – simply go back over anything you don’t understand and remember, practice makes perfect – the more you do it, the better you will get.

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.
