Post Description

Bekende databases om grote hoeveelheden gegevens in op te slaan zijn natuurlijk Oracle met zijn 11g-database, IBM met de DB2-database en Microsoft met SQL Server. Een ander database management system is Firebird, dat als oorsprong de Interbase-database van Inprise heeft, tegenwoordig bekend als Borland Software, waarvan de geschiedenis op deze pagina na te lezen is. Deze relationele database kan op verschillende besturingssystemen geïnstalleerd worden, waaronder het Linux- en het Windows-platform, waardoor het breed kan worden ingezet.
