Yeah this is a better idea as you can start pusing only small slices of functionallity to the real db doing the rest in memory.

Like when implementing veritas adapters.

I'd actually use the InMemoryAdapter as a basis to work from.  It just
keeps everything in core ruby data structures, so it's easy to follow
and swap out the code with your own implementation.

To see examples of doing query build etc, look at others, yep :)

The best documentation are existing adapters.

An adapter that is easy to follow (IMHO) is the dm-mongo-adapter.

You can find it under https://github.com/solnic/dm-mongo-adapter.

The RDBMS adapters are a littlebit more complex to understand as they
are implemented on the abstract dm-do-adpater. But when you whant to
start an RDBMS adapter you should built it on top of dm-do-adpater.

Hi all

I'm looking to create a new adapter for DataMapper. Is there a template
that I can use as a starting point, or a document that I can refer to
that explains the process?

Thanks
Greg
