Tagging things with device type (in a consistent way) will certainly
help when you're looking for a part in the database. It needn't be
relevant for simulation - if that's what you mean.

Good database design dictates that the device types are not hard-coded
into the data-structure, there is no explicit "resistors" table JOIN'd
to drag in resistor specific data etc..
