History[05]
Kappa was developed as part of the the "Fifth Generation Computer Systems" initiative in the 1980s by Japan's Ministry of International Trade and Industry (MITI) to create computers using massively parallel computing and logic programming.
The last version of Kappa was released in 1999.
Data Model[06]
Kappa uses a "nested relational model" that is similar to the document model in that it supported non-scalar values (e.g., arrays, nested records). It is seen as a precursor to object-relational model.
