The Structured Query Language (SQL) is one of the most widely used database languages in the world. SQL is used to manage data found in a database, including data organized in tables.
SQL allows you to create, manage and manipulate the data contained in a database according to your needs and requirements.
With SQL, you can query, update, reorganize and update data, control access to database system data, and create and modify the scheme (structure) of databases in your system.
SQL can not only create, but also remove existing components, change the properties of database objects, rename database tables, and delete data from those tables. SQL commands enable the creation of procedures that store information about the data of the database system such as data type, data structure, database object type and data types.
Popular server-side scripting language PHP has inbuilt support for SQL databases such as MySQL and MariaDB (an open-source alternative to MySQL). PHP allows developers to connect and query a database using SQL to retrieve and store data.
Popular content management systems such as
WordPress rely on SQL to provide back-end storage of pages, users, posts and comments, and without this common language it wouldn't be possible to create dynamic websites on the
world wide web.
Whilst fetching small amounts of data from a database can be fast, when this workload is scaled, or the amount of data increases, the performance decreases.
It's important to look at both
web caching, and clustered
virtual private servers connected together to provide load balanced SQL servers to provide a better user experience. We suggest checking out
