MySQL is a Relational Database Management System (RDBMS) that uses Structured Query Language (SQL). It is also free and open source.
MySQL is free and open-source software under the terms of the GNU General Public License, and is also available under a variety of proprietary licenses. MySQL was owned and sponsored by the Swedish company MySQL AB, which was bought by Sun Microsystems (now Oracle Corporation).In 2010, when Oracle acquired Sun, Wideness forked the open-source MySQL project to create MariaDB. MySQL is a component of the LAMP web application software stack (and others), which is an acronym for Linux, Apache, MySQL, Perl/PHP/Python.

FEATURES OF ANDROID
The fact is that there is an ever increasing number of MySQL users, and the overwhelming majority of them are quite satisfied with MySQL. Thus for these users we may say that MySQL is good enough.
MySQL is a relational database system. If you can believe many diehard MySQL fans, MySQL is faster, more reliable, and cheaper — or, simply put, better — than any other database system (including commercial systems such as Oracle and DB2). Many MySQL opponents continue to challenge this viewpoint, going even so far as to assert that MySQL is not even a relational database system.
Triggers are SQL commands that are automatically executed by the server in certain database operations (INSERT, UPDATE, and DELETE). MySQL has supported triggers in a limited form from version 5.0, and additional functionality is promised for version 5.1.
It is also the fact, however, that MySQL still lacks a number of features that are taken for granted with other database systems. If you require such features, then MySQL is (at least for the present) not the database system for you. MySQL is not a panacea.
MySQL supports as its database language — as its name suggests – SQL (Structured Query Language). SQL is a standardized language for querying and updating data and for the administration of a database. There are several SQL dialects (about as many as there are database systems). MySQL adheres to the current SQL standard (at the moment SQL:2003), although with significant restrictions and a large number of extensions.
