Over on PHPEverywhere there's a new posting that sings the praises of a "portable database creation layer".

For those out there that are confused, a creation layer like this one allows you to create databases on the fly, quickly and easily, without having to worry about the SQL behind it all. Functions like "CreateTableSQL" and "CreateDatabase" help you to easily make truely dynamic databases a real posibility. This page details all of the features and functions that you'll need to get started, complete with examples and suggested uses for each method.

With functionality like this, I can imagine that places like hosting companies will be amazingly happy - not only because through this layer they can create the databases they need, but, coupled with a good DB layer, they can create them on any platform of their choosing...
