  3. 3. MySQL MySQL is the most popular Open Source Relational SQL database management system. MySQL is a very fast, reliable, multi-user and easy- to-use RDBMS which is being used for many small and big businesses. Developed By: MySQL is developed, marketed, and supported by MySQL AB(aktiebolag), which is a Swedish company. The Developers: David Axmark, Allan Larsson and Michael "Monty" Widenius.
  4. 4. "My"SQL : Trivia The derivation of the name MySQL is not clear. The following two opinions persist:- The original base directory and a large number of the libraries and tools have had the prefix "my" for well over 10 years. However, co- founder Monty Widenius's daughter is also named My. Which of the two gave its name to MySQL is still a mystery! ' The name of the MySQL Dolphin (our logo) is "Sakila".
  5. 5. Main Features of MySQL:- The Written in C and C++. APIs for C, C++, Eiffel, Java, Perl, PHP, Python, Ruby, and TCI are available. Provides transactional and non-transactional storage engines. Uses very fast B-tree disk tables (MylSAM) with index compression. Function names do not clash with table or column names. For example,ABSis a valid column name. The only restriction is that for a function call, no spaces are allowed between the function name and the '(' that follows it. Up to 64 indexes per table are allowed (32 before MySQL 4.1.2). Each index may consist of 1 to 16 columns or parts of columns. The maximum index width is 1000 bytes (767 forlnnoDB); before MySQL 4.1.2, the limit is 500 bytes. An index may use a prefix of a column forCHAR, VARCHAR, BLOB, or TEXTcolumn types.
