The product is an aggregator of sorts, very flat domain. The only thing apart from the items being collected are categories which are denormalized on aggregation - they have a short lifespan anyway. RE: Write/Read/Update heavy, it's going to be a mixture. Once users are present it will be read heavy. The backend is constantly collecting new data and updating if changes are spotted. I'm 99% certain a document database/ non-relational approach is suitable here. I have nothing against MongoDB - I just want to make these decisions now. I've enjoyed using it so far. Thanks for feedback!
