This document provides an overview of MariaDB, including: - MariaDB is an open-source database that is a fork of MySQL with additional features and enhancements. - It was first released in 2009 and is overseen by the MariaDB Foundation. SkySQL, formed by former MySQL executives, merged with MariaDB founder Michael "Monty" Widenius' company in 2013. - MariaDB offers various storage engines, new features like dynamic columns and NoSQL access, and generally better performance than MySQL through optimizations and user statistics. It is widely adopted with major investors and supporters.

- 2. Agenda • What is MariaDB? • History • General Information • Storage Engines • New Enhancements • Live Demo ! • Finish
- 3. What is MariaDB • MariaDB is the world's fastest growing open source database • Its MySQL but with better features ad enhancements • Based on the open source MySQL code. It is a branch, or fork, of the source code • MariaDB is available under the terms of the GPL v2 license. • First Release was on 22 January 2009
- 4. MariaDB History • Released on 22 January 2009 • In December 2012, MariDB Foundation was announced as the foundation that would oversee the development of MariaDB • SkySQL, a company formed by ex-MySQL executives and investors after Oracle bought MySQL, announced in April 2013 that they were merging their company with Monty Program Ab, and joining the MariaDB Foundation
- 5. MariaDB Founder Michael "Monty" Widenius • Monty has worked on the MySQL/MariaDB codebase since 1981. At least 60% of the MySQL code is still his. He is a MySQL Fellow and is the founder and CEO of Monty Program Ab and the creator of MariaDB.
- 6. General Information Initial release 22 January 2009 Stable release 10.0.10 March 31, 2014 Written in C, C++, Perl, Bash Operating system Cross-platform (Unix, Windows, Solaris, Linux, OS X, BSD) Type RDBMS License GNU General Public License (version 2), GNU Lesser General Public License (for client-libraries) Ports 3306 Security Provide different Access levels and Locations Arabic Support Arabic Language (UTF8, Win1256)
- 7. Storage Engines Xtradb is a good general transaction storage engine and usually the best choice if unsure Aria improved version of MyISAM in MySQL Cassandra NoSQL engine CONNECT allows access to different kinds of text files and remote resources as if they were regular MariaDB tables SphinxSE is used as a proxy to run statements on a remote Sphinx database server (mainly useful for advanced fulltext searches) ScaleDB is a commercial storage engine suited for large-scale online transaction processing and data warehousing FederatedX allows to access tables in different servers OQGRAPH Open Query GRAPH computation engine for retrieving hierarchical information, such as those used for graphs, routes or social relationships, in plain SQL
- 8. New Enhancements • Dynamic columns Allows one to store different sets of columns for each row in a table. It works by storing a set of columns in a blob and having a small set of functions to manipulate it. A typical use case is when one needs to store items that may have many different attributes (like size, color, weight, etc), and the set of possible attributes is very large and/or unknown in advance. In that case, attributes can be put into dynamic columns. • NoSQL : It provides developers with fast, direct access to InnoDB tables by skipping the SQL layer • Better Performance • Enhance Optimizer engine • Subquery optimizations: Now its really working • User Statistics: This feature adds several new information schema tables. These tables and commands can be used to understand the server activity better and to identify the sources of your database’s load.
