Hi Paul ,

Thanks for attention and considering the proposal of having feature for
database name specification for tenantCreation.

Yes I use XML-RPC thoroughly as i mostly use OFBiz as a framework
for generic data models rather than the OOTB. In such a development model
I feel joining tables and getting data from DB is much more efficient than
implementing DB like activities in application code. (ie. utilising xml-rpc)

Sparingly i require to access the ofbiz entities directly and that is where
having ofbiz entities in a schema of existing database comes handy.

Its true that scaling requirements of the two applications can be different
and tying them into same DB may lead to redundant allocations.

But i still feel having flexibility shall be a boon as we never know how
creative people get with their setups!. OFBiz is already a very flexible
architecture for that matter.

I guess the default behavior of the command can be left like that and
for those who need more flexibility there can be fine grained options
for overriding the default values.
