SQL - Platforms

SQL - MySQL and PostgreSQL

MySQL and PostgreSQL are open source database programs rich in functionality and flexibility. They are often the choice of web developers and small businesses simply because they get the job done for a very reasonable price. Also they will go anywhere and can operate on nearly every operating system available.

SQL - SQL Server

Microsoft's SQL Server is steadily on the rise in the commercial world gaining popularity slowly. This platform has a GUI "Windows" type interface and is also rich with functionality. A free trial version can be downloaded at the Microsoft web site, however it is only available to Windows users.

SQL - DB2 and Oracle

By far the selection of choice for large corporations is either Oracle or DB2. Companies that have large ties to IBM stick to their DB2 software whereas others have made the switch to Oracle. These systems run on personal computers as well as large corporate mainframes.
