Amber is independent of your choice of model architectures. We (Core members) have built the ORM Granite. We also think Jennifer built by Roman Kalnytskyi is a good option.


Granite provides a light weight ORM that is focused on taking the results of your query and mapping them to your model. It does not try to shield you from the SQL that lies underneath the mapping. It provides a couple conveniences like save and destroy for simple INSERT, UPDATE and DELETE statements. It provides find, find_by and all to query the database. It also has basic one-to-many relationships with belong_to and has_many.

Jennifer provides an more full featured ORM with a full featured DSL for queries and follows the ActiveRecord pattern found in Rails. If you are looking for a full featured ORM, Jennifer may be your choice of ORM.

Of course you are not limited to only these options. You may have a need for a high throughput, large dataset, dynamic structured db like MongoDB or you need to connect to a microservice or a legacy mainframe. By not being tied to a specific model, we don't limit the possible integrations you may need.
