Dunno... basically BigTable is the same as Amazons SimpleDB: a loose
property store with no relations in it. You can model them with some
tricks, though. But it still doesn't make that good of a match with EOF.
I'd rather wonder how they run their "servlets"? Can they keep state?
How?

I found this little snippet from way back in 03:
Damon Clinkscales's "Object Persistence Approaches" presentation
further compared JDO and EJB with WebObjects's Enterprise Objects
Framework (EOF). EOF is a third-party object persistence framework
library owned by Apple and provides the technology behind the Apple
e-commerce Website. Since EOF is a pure Java library, it does not
require complex containers (EJB) or byte code post-processors (JDO).
EOF provides access to the generated raw SQL, and adaptors can
provide access to nonrelational datastores. However, EOF is a
nonstandard vendor-specific technology. It requires the developer to
learn the proprietary API and creates vendor lock-in.

So it sounds like a specific adaptor will have to be created for the
Google Datastore?

WO in the cloud, anyone?
Hmmm. I guess that could be really interesting if there were an EOF
integration for JDO. Will have to look into that. It's definitely
an interesting option.
