What you'll learn:
- understand the basic concepts of databases
- get a good grasp of SQL and MySQL queries
- understand database management systems (DBMSs) and database languages
- understand table manipulation
- understand pages
- understand views
- understand strored procedures
- understand the data structures (B trees and B+ trees) behind databases
In this course you can learn the fundamental basics of data management with SQL and MySQL. Learn everything that you will need to make queries with the most popular data manipulating programming language - SQL. This course is about SQL commands in the main. You will learn the basics of queries. Let's take a look at what you are going to learn in this course:
Section 1 - Setting up The Environment:
setting up the environment
installing MySQL server
Section 2 - Database Theory
what are databases?
what are database management systems (DBMSs)?
what are database languages?
the data structures (B-trees) behind databases
procedural and non-procedural programming languages
Section 3 - Creating and Manipulating Tables
basic data types (integers, floating point numbers and characters)
enums and dates
how to create databases?
how to insert and remove items?
how to update existing items or database tables?

Section 12 - Stored Procedures
what are stored procedures?
variables
loops
conditional statements
cursors
Learning the fundamentals of SQL and MySQL is a good choice and puts a powerful tool at your fingertips. SQL is easy to learn as well as it has excellent documentations.
The most important fact about SQL that it is used in almost every field from software engineering to financial analysis so understanding the concepts and basic language features can prove to be very marketable.
