David's argument is for a single-app database, because he doesn't believe that applications should integrate directly with each other's databases. As such, all databases are single-app databases. The alternative being integration by specific hooks, RPC, object brokering, etc might take more time, yes, but is also ultimately more flexible. Systems do not have to be physically as near and the protocols used can be much better protected. HTTP, used by SOAP and XMLRPC for example, is far easier to secure and firewall then SQLnet used by Oracle. This ultimately boils down to a difference in opinion on design.
