Object Relational Impedance Mismatch Links

See ObjectRelationalImpedanceMismatch, ObjectRelationalImpedanceMismatchDoesNotExist, ArgumentsThatTheObjectRelationalImpedanceMismatchDoesNotExist, TablesAndObjectsAreTooDifferent, ObjectRelationalMappingCostsTimeAndMoney

I thought it is good to put here some useful links to serve as a background for the discussion. Please help me to add, probably I'll miss a lot of useful links.

On OO side of the story

KyleBrown and BruceWhitenack: CrossingChasms

ScottAmbler: Mapping Objects to Relational Databases http://www.ambysoft.com/mappingObjects.pdf. This paper is a little old and rusty and suffer from obvious flaws. A more elaborate essay you can download from http://www.theserverside.com, see the book in progress there, complex persistence chapter.

EnterpriseJavaBeans is a very good example of how things got derailed because of a psychological impedance mismatch. You can see the quasi-majority of patterns related to them are supposed to solve a thing that is broken by the specification.
