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 Structured Query Language.
A relational database organises data into one or more data tables in which data types may be related to each other;
these relations help structure the data. SQL is a language programmers use to create, modify, and extract data from the relational database, as well as control user access to the database. RDBMS like MySQL works with an operating system to implement a relational database in a computer’s storage system, manages users, allows for network access, and facilitates testing database integrity and creation of backups.
MySQL, the most popular Open Source SQL based database management system, it’s managed and supported by Oracle Corporation.
It is also called Relational Database Management System based on SQL – Structure Query Language. It is used for various purposes for example. E-commerce, Inventory System, Data-Warehouse, etc.
PHP/Perl mostly used MySql for storing the data. Most f CMS like WordPress, Drupal default database is MySql.
Use of MySQL
Mysql used for storing data into a database using SQL (Structured Query Language). It’s very easy and simple to add/edit and delete records/data from MySql Database.
MySql Database is free and open-source with a commercial license available (Now, owned by Oracle). PHP and Java mostly use MySql Database to store their backend.
Many CMS uses MySql by default. Like WordPress, Drupal, etc. to store their feature and data.
MySQL provides many storage engines but usually uses InnoDB, MyISAM storage engine,
MyISAM doesn’t support transactions, so that you can not commit and rollback and each table having 3 sets of files (.frm, .MYD, .MYI).
InnoDB is a supported transaction, which means you can commit and rollback.

Advantage of Mysql
1. On-Demand Scalability: MySQL is used by many applications demanding availability and scalability. Availability refers to the ability to cope with, and if necessary recover from, failures on the host, including failures of MySQL. The operating system, or the hardware and maintenance activity that may cause downtime.
Scalability refers to the ability to spread both the database and a load of your application queries across multiple MySQL servers.
2. Performance: Performance is very important for any database management system, MySql having great performance. MySQL designed to provide quickly get data in (insert/update) and also quickly get it out (select). It generally has better performance on simple queries we use every day, such as primary key, range queries, insert/update, etc. MySQL performs well as the data size grows, from GB to several TB of data.
eCommerce website that receives a million queries every single day or a high-speed transactional processing system, MySQL is designed to meet even the most demanding applications while ensuring optimum speed, full-text indexes, and unique memory caches for enhanced performance.
The newest storage engine InnoDB, now the default engine for new tables, has been re-architected to take advantage of multi-core systems
3. Portability: MySQL is a cross-platform database server. It can run on different platforms like Linux, Solaris, and Windows, etc. MySql supports many platforms with different languages like C, C++, PHP, PERL, JAVA, Python, etc.
4. Seamless Connectivity : MySql offers Seamless connectivity. like. Pipes, TCP/IP sockets, and UNIX Sockets.
5. Rapid Development and Round-the-Clock Uptime: MySQL assurance of 24X7 up time and offers a wide range of high availability solutions like specialized cluster servers and master/slave replication configurations
6. Data Security: MySql is a very secure and reliable database management system used in popular web applications like WordPress, Drupal, Joomla, Facebook, and Twitter. MySql can greatly benefit any business especially if it is an eCommerce business that involves frequent money transfers.
7. Comprehensive Transactional Support: Mysql has Robust transactional database engines available on the market. With features like complete atomic, consistent, isolated, durable transaction support, multi-version transaction support, and unrestricted row-level locking, it is the go-to solution for full data integrity. It guarantees instant deadlock identification through server-enforced referential integrity.
8. Complete Workflow Control: MySQL’s average download and install time is about 30min. and if you are using Linux, Microsoft, Unix. MySQL is self-management features that automate everything from space expansion and configuration to data design and database administration.
9. Reduced Total Cost of Ownership: MySQL, enterprises enjoy significant cost savings on new projects. Easy of management can save troubleshooting time and save wasted in fixing downtime issues and performance problems.
10. The Flexibility of Open Source: MySQL is free and open-source. And all the fears and worries that arise in an open-source solution can be brought to an end with My SQL’s round-the-clock support and enterprise indemnification. The secure processing and trusted software of MySQL combine to provide effective transactions for large-volume projects. It makes maintenance, debugging, and upgrades fast and easy while enhancing the end-user experience.
