MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [6] is an open-source relational database management system (RDBMS). [6] [7] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [1] and "SQL", the acronym for Structured Query Language.
WebScaleSQL – software branch of MySQL 5.6 jointly developed by Facebook, Google, LinkedIn and Twitter to provide a centralized development structure for extending MySQL with new features specific to large-scale deployments, such as building large replicated databases running on server farms. The project's objective is to tightly follow new ...
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...

Codd's twelve rules [1] are a set of thirteen rules (numbered zero to twelve) proposed by Edgar F. Codd, a pioneer of the relational model for databases, designed to define what is required from a database management system in order for it to be considered relational, i.e., a relational database management system (RDBMS).
Note also a type called an internal JDBC driver - a driver embedded with JRE in Java-enabled SQL databases. It is used for Java stored procedures . This does not fit into the classification scheme above, although it would likely resemble either a type 2 or type 4 driver (depending on whether the database itself is implemented in Java or not).
Ulf Michael Widenius (born 3 March 1962), also known as Monty, is a Finnish software programmer. He is the main author of the original version of the open source MySQL database, a founding member of the MySQL AB company, founding member of the MariaDB Foundation and CTO of the MariaDB Company.
Thus, MariaDB 5.5 offers all of the MySQL 5.5 features. There exists a gap in MySQL versions between 5.1 and 5.5, while MariaDB issued 5.2 and 5.3 point releases. Since specific new features have been developed in MariaDB, the developers decided that a major version number change was necessary. [11] [12]
