I need to do transactions (begin, commit or rollback), locks (select for update). How can I do it in a document model db?

Edit:

The case is this:

I want to run an auctions site.
And I think how to direct purchase as well.
In a direct purchase I have to decrement the quantity field in the item record, but only if the quantity is greater than zero. That is why I need locks and transactions.
I don't know how to address that without locks and/or transactions.

Can I solve this with CouchDB?
