I would be especially nervous trying to do all the behind the scenes stuff (referential integrity, type enforcing,etc.) let alone trying to optimize ways to store and look up columns.

There might be benefits to simple databases of small sizes, but for hefty applications, I'll stick with the Sybases, Oracles, and DB2s.
