Nitro/Og does not provide or require an IDE. You can use the IDE
that suits you.

Supported at run time or development time, Nitro/Og generates most
of the code for you.

No configuration at all, use standard Ruby objects.

Supported, Og uses RDBMS backends to emulate an OODB environment.

You can switch backends (for example go from Mysql to Postgres) by
changinf a single line.

Automation / Code generation is the main feature.
