I have to look it up and see what I can share. I have it in a git branch in a local repository. I will be getting back to this in the future as we will probably move forward with this. We have some tables that are huge and we want to start using Mongo DB to store that information. The tables outgrew the limits of an integer for the primary key years ago.
The object graph that I deal with is similar to a document. The parent owns the children. It only has one reference to a user object which it does not own.
I also had special requirements. I needed to still be able to read existing data from our relational oracle database. So the model is really mapped to oracle and can fetch from it. Then I wrote code to save to mongo for new data generated. And I can also fetch from mongo.
Anyways in the (near I hope) future I'll be getting back to this project.
