Our application is used by different companies for their operation and will be
accessible over internet. We want to have separate databases for each company
and the application will interact with all the databases to enable
buyer-supplier relationships etc. With this we can offer local systems for
large companies which can synchronize with the central server periodically.

Basically we want to ensure that the data is owned by the concerned companies,
and in case they want to break away from our service, we just take out their
database and give to them.

As far as I understand having separate schema will not server our purpose. We
will have to look at other options now it seems.

Best regards,

Siva
