1970 E.F. Codd has started a revolution with his paper 'A relational model of data for large shared data banks, Communications of the ACM, Volume 13, Issue 6 (June 1970)' that finally led to the today's omnipresent database query language SQL.

This little app shows some primitive and derived operations with the following information:
