Hierarchical and Network were the defacto standard way of doing 
databases back in the 1960s, and Codd introduced the Relational model 
of data to address their deficiencies.  So the Relational model 
wasn't the first model, it came later, like C and friends came awhile 
after Cobol, which was serious. -- Darren Duncan
