Date Wed, 23 Feb 2011 20:08:38 GMT


Morten Lied Johansen commented on CAY-1543:

Unfortunately, I don't have the skills to help with this project, and more importantly, I
don't have the time. :(

>                 Key: CAY-1543
>                 URL:
>             Project: Cayenne
>          Issue Type: Wish
>          Components: Database integration
>            Reporter: Morten Lied Johansen
> The big feature most developers seek when working with Cayenne or any other ORM is the
ability to work with their objects and let the framework take care of translating that object
into something that can be stored in a database.
> The R in ORM is actually not an important feature, it's a side-effect of the components
most normally used.
> It would be great if Cayenne could step away from the R part and instead become an Object-Persistence-Mapper
(or whatever other terminology you wish to use), and support other non-relational databases,
such as Cassandra or MongoDB.
> Before you say this is impossible, there is work being done with exactly this in mind
over in Python-land, where the django-nonrel project (
aims to provide the Django-ORM with support for non-relational database backends, with great
success so far.
