When you have to convert a database it is a consideration. But when
you are producing a solution with this in mind from the start it is
no extra construction work.

If you dispute this that's one thing, but adding an unwarranted
database conversion to the consideration of the complexity of
one solution vs another in this comparison is just unfair.

I could equally argue that it's more difficult to implement non
large coordinate management database than large coordinate
management database if I start with a database for the latter.
This claim would be equally silly and prejudicial. If you build a
database with the right solution in mind from the start one is
as easily built as each other.

Cheers,Angus.
