two-way connection between objects and anything done to one is reflected to the connected object

still not very clear. Are you saying that changing a field, lets say name in a record that has a reciprocal relation, would also change the name of the related object ?
perhaps an example would help.[/quote]

Nope. Fields are not connected in DataMapper, records are. And they are not connected within the records themselves but by a separate mapping table. There are no foreign keys in your basic tables.

So, changing data within a record has no affect on anything it's joined to, regardless of the type of relationship between the records.

Reciprocal relationships only matter with record insertion or deletion. An example would be the deletion of a user and it causes all the postings and comments by that user in a blog system to also be deleted.
