A quick Google search fill find plenty of relevant material, such as
Note that Codd's relational rules are nothing to do with his later, and
much less respected, OLAP rules.
Codd played a big role in inventing the relational database, so although
his relational rules are rather theoretical, they still have some
limited relevance some 20 years later. They were, in any case, based on
genuine research. On the other hand, he knew almost nothing about OLAP,
and had little to do with creating his 12 or 18 OLAP rules, which were
based on the features of Essbase, whose vendor sponsored the white
paper.
