Description: MariaDB database server (metapackage depending on the latest version)
 +
This is an empty package that depends on the current "best" version of
 +
mariadb-server (currently mariadb-server-10.0), as determined by the MariaDB
 +
maintainers. Install this package if in doubt about which MariaDB
 +
version you need. That will install the version recommended by the
 +
package maintainers.
 +
.
 +
MariaDB is a fast, stable and true multi-user, multi-threaded SQL database
 +
server. SQL (Structured Query Language) is the most popular database query
 +
language in the world. The main goals of MariaDB are speed, robustness and
 +
ease of use.</pre>
