A List of Database Management Systems

This is a list of all the database management systems that I have been able to identify. If you know of any others, then please email them to me! The systems are listed by type: relational(R), extended-relational(X), object-relational(OR), object-oriented(OO), network(N) and hierarchical(H). Note that some vendors state that their DBMS is more than one of these. In such a case the DBMS type is specified by more than one designation. For example, Centura Software states that their Velocis database is based on both the relational and network models, and in this case the designation "RN" has been specified.
For the primary market, some liberties have been taken with regard to the use of the term "Enterprise." Specifically, if a vendor does not indicate a primary market for their DBMS, then the primary market has been specified as "Enterprise."
