The example is from a python ERP that I modified a few years ago. All the db interaction was done through an ORM and I thought that it was an OK strategy for keeping the SQL consistent and manageable. There were other problems with the ORM approach -- mostly that it ran tens or hundreds of extra queries for relatively straightforward SQL queries. But the software was only used by a few people at a time, so the performance wasn't that big of a deal.
