True Relational To Pseudo Relational Impedance Mismatch

last modified: November 21, 2014

The TrueRelationalToPseudoRelationalImpedanceMismatch is a label that could be used for the set of problems that could be encountered when using a PseudoRelationalDatabase (BagAtational?), as the mechanism for storing the data for a TrueRelationalToPseudoRelationalMapper.

Does it really exist? Does it.. for example, force you to allow nulls in your otherwise perfectly complaint TrueRelationalToPseudoRelationalMapper? or those are just problems with particular implementations ?

Some of the possible mismatches could be:

Are this real problems/mismatches? or perhaps TrueRelationalToPseudoRelationalImpedanceMismatchDoesNotExist and one can perfectly wrap PseudoRelationalDatabase under a TrueRelationalMapper? or perhaps that wrapping is only possible as long as the PseudoRelationalDatabase has TuringComplete PersistentStoredModules?
