- That brings up an interesting question. I've lately been looking into a number
- of SQL databases. As I understand it, Raima claims that for their database,
- the user can either choose to use or not to use the network capabilities, and
- that even if you do, the view to the user is always relational.
-
- How important is the network structure to Raima Data Manager? They claim it
- speeds up queries--is it slower than other databases if you don't use it? Does
- the database look any different to the user than if it were maintained with a
- purely relational engine?
