ADABAS
<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 groups}.
