< database > A relational database system by Software AG . While it was initially designed for large IBM mainframe systems (e.g. S/370 in the late 1970s), it has been ported to numerous other platforms over the last few years such as several flavors of Unix including AIX .
ADABAS stores its data in tables (and is thus "relational") but also uses some non-relational techniques, such as multiple values and periodic group s.
