- 3. Introduction: MYSQL is an open-source relational database management system(RDBMS). Its name is a combination of “My", the name of co- founder Michael Widenius’s daughter and “SQL” ,the abbreviation for structure Query Language MYSQL is free and open-source software under the terms of GNU General Public License and is also available under a variety of proprietary licenses.

- 13. IT IS SCALABLE : MYSQL can handle almost any amount of data , up to as much as 50 million rows or more . The default file size limit is about 4GB. COMPATIBLE ON MANY OPERATING SYSTEM: MYSQL is compatible to run on many operating system , like novel NetWare , window * Linux * many varieties of UNIX*
- 14. ALLOWS ROLL-BACK: MYSQL allows transaction to be rolled back , commit and crash recovery . HIGH PERFORMANCE : MYSQL is faster , more reliable and cheaper because of its unique storage engine architecture. HIGH FLEXIBILITY: MYSQL supports a large number of embedded application which makes MYSQL very flexible
- 15. MySQL FUNCTIONALITIES: This section gives the most commonly used MYSQL function including aggregate function , string functions , string functions , data-time functions , control flow function , etc. MYSQL AGGREATE FUNCTION : aggregate function allows to perform a calculation on a set of records and return a single value. MYSQL aggregate function including SUM , AVG , MAX , MIN and COUNT function.
- 16. MYSQL comparison function: Comparison function in MYSQL including COALESCE , GREATEST , LEAST and ISNULL . MYSQL control flow function and expression – the control flow function allow add if-then-else logic to SQL queries without using the procedural code MYSQL window Function – this tutorial introduces to MYSQL windows function and provides with some practical and motivational e.g. of the window function in MYSQL
- 17. Tools, advantages and real-life scenario example: MYSQL TOOLS: MYSQL workbench is available on windows, Linux and Mac OS x. Design – MYSQL workbench enables a DBA , developer or data architect to visually design , model ,generate and manage database. Develop – MYSQL workbench delivers visual tools for creating , executing and optimizing SQL queries . The SQL editor provides color syntax highlighting ,auto-complete, reuse of SQL snippets and execution history of SQL.
- 18. Administer – MYSQL workbench provides a visual console to easily administer MYSQL environments and gain better visibility into database . Database Migration – MYSQL workbench provide a complete ,easy to use solution for migrating Microsoft SQL server.
- 19. MYSQL Advantage MYSQL is a free-to-use ,open-source database that facilitates the effective management of database by connecting them to the software . It is a stable, reliable and powerful solution with advanced features follow : Data security– MYSQL is globally renowned for being the most secure and reliable database management system used in popular web application
- 20. High performance: it has features a distinct storage engine framework that facilitates system administrators to configure the MySQL database On –demand scalability Round-the-clock uptime Comprehensive transactional The flexibility of open sources
