If you want your web site to be able to store and display data from a database, your web server should have access to a database system that uses the SQL language.
If your web server will be hosted by an Internet Service Provider (ISP), you will have to look for SQL hosting plans.
The most common SQL hosting databases are MySQL, MS SQL Server, and MS Access.
You can have SQL databases on both Windows and Linux/UNIX operating systems.
Below is an overview of which database system that runs on which OS.
MS SQL Server
Runs only on Windows OS.
MySQL
Runs on both Windows and Linux/UNIX operating systems.
MS Access (recommended only for small websites)
Runs only on Windows OS.
