MySQL is a Relational Database Management System. A relational database includes speed and adaptability, by putting away information in discrete tables instead of putting every one of the information in one range. These tables are connected by characterized relations making it possible to combine information from a few tables upon request.
Using an RDBMS implies it is possible to add, get to, and process the information stored in your database.
"SQL" means for "structured Query Language" - the most widely recognized language used to get to databases.
