Good Morning Aamir Khan.
Technically, you could install SC with it's own mdb database.
But in practice and real live no, you can not install SC with a separate mdb database.
It will make it impossible to integrate the two products (SDM and SC) in any way.
There is no way to then create any possible link or connection between the two products.
With this said it is almost mandatory to have both products share their mdb database.
And it is then not recommended in any way, to have them both installed with a separate database.
Thanks and kind regards, Louis van Amelsfort.
