One of the open-source relational database management system is MySQL, name of the mySQL is originated by the combination of name of the founders daughter with My “Monty Widenius’s daughter: My”, It was first released in 1995
From the relational database programmers extract the data using functions create, modify and extract data also control user access to the database.
MySQL is works under the general public liecense(GNU), first it was owned by MySQL AB, which later brought by Sun Microsystems which now known as oracle corporation, MySQL allows users to interact directly with a MySQL database using SQL due to its has stand-alone clients availability. However, MySQL is often practiced with other programs to execute applications that need relational database capability.
Its written in c and C++ language, MySQL is very fast, reliable, scalable, and easy to use
Big companies like Facebook, Airbnb, Twitter, Booking.com, GitHub, Uber, YouTube, etc. event the Content Management organizations WordPress, Drupal, Joomla!, Contao, etc also big player in the industry using MySQL to manage the database.
When we talk about mySQL, SQL also comes in our mind. However, MySQL is a database that stores the existing data in a database in an organized manner, and SQL is a query language. In contrast, MySQL is a relational database that practices SQL to query a database. You can use SQL to update, access, and manipulate the data stored in a database.
It’s a organized way of storing data, so that we can easily access as well as manage. Database is to organize data into rows and columns in the table
