MySQL is common in Open Source Relational SQL Database Management System. It is a quick, easy-to- use RDBMS being used for many small and big companies. MySQL is evolved, marketed and supported by MySQL AB, which is a Swedish company. Nowadays MySQL is becoming so popular because of many good reasons −

• MySQL is customizable. The open-source GPL license enables programmers to change the MySQL software to fit their own particular environments.
• MySQL works very fast and works well even with large data sets.
• MySQL supports large databases, up to 50 million lines or more in a table. The default file size limit for a table is 4GB, but you can extend this (if your operating system can manage it) to a theoretical limit of 8 million terabytes (TB).
• MySQL uses a standard form of the well-known SQL data language.
• MySQL is very friendly to PHP, the most recognized language for web development.
• MySQL is a very robust program in its own right. It handles a large subset of the functionality of the most expensive and strong database packages.
• MySQL works on many operating systems and with many languages including PHP, PERL, C, C++, JAVA, etc.
