One Vault - as vaulting strategy for Enovia

Hi All,

I wish to understand why Dassault starts recommending "One Vault" strategy for storing business objects.

What could be the maximum number of business objects a single vault can potentially store without affecting the application performance (like "search" etc ) ?

If we are going to have huge volume of data pertaining to two different business domains that are not related to each other, can we explore the possibility of having two vaults ?
