ETL framework for loading data into Rails app
If you are just loading data into a set of tables, and the use case is simple such as just adding new records or updating basic ones, and your load is meeting your requirements, I would stick with that. You could certainly use ActiveWarehouse as well, but it sounds like overkill. If, however, you need to support changing dimensions (ie. preserve history of data changes over time), or other 'data warehouse' features, then something like ActiveWarehouse starts to have more value.
