Then you should say the *Pure* OODB data model.

With Pure as a proper noun and not as and adjective.

I seached: "Pure OODB Model" and "Pure OODB Data Model" and I have got 0 results.

If you talk about gnomes everybody will know what you are talking about. It does not mean that they exist.

I have searched for "Pure OODB" and I only have found two Van den Bussche's papers, many of them cited using lower case.

But I have found many other "pure OODB's" like Objectivity, GemStone, etc.

"Pure OODB's are a special case, but of course so is a relational database (Abiteboul et al. op. cit.)"

"Summary: Pure OODB and RDB are fundamentally based on the same mathematical concept of relations. In RDB, it is relation/values. In OODB, the equivalent is class/instances."

Talk about yourself only ;)

It is a shame that supposed researchers are publishing that rubbish using public funds.

The IT world is far from being serious and the academy is not an exception.

I have found all kind of foolish things in academic texts about databases.
