It's not normal form (Score:2)

by autarch (914)

The normal forms are all about _logical_ issues. What you're describing is purely an implementation detail of how some databases handle BLOBs, and the workaround you suggest has nothing to do with the logic of your data model.

In a better world, the DBMS engine would do this sort of thing transparently, or at least provide ways for DBAs to manually split the physical storage of tables across multiple locations.

  True enough. Still, this is a Good Practice. We do this in Slash too: the actual text of stories, comments, journals, etc. are all in their own table, with only the primary key.
