Comparison of object-relational database management systems
Encyclopedia
The following Database Management Systems (DBMSs) have at least some object-relational features. They vary widely in their completeness and the approaches taken.
The following tables compare general and technical information for a number of object-relational database management systems. Please see the individual products' articles for further information. This article is not all-inclusive or necessarily up to date. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions or external programs.
