Ian Bicking: the old part of his blog


ORM tools have two different jobs depending on what comes first in the design: with objects first there is persistence, portable to different datastores because the objects remain the same and as transparent as possible because one only needs to write objects and get them back; with database first there is a struggle to perform database operations and present data as objects in the context of a certain program: the transparency and portability are turned around (any program can use the OO view of a certain database provided by the tool and all database clients are the same).
