Honestly, if you're finding it hard to plan that's an indication to me that NoSQL isn't a good fit and you actually need relationships.

Yes. Coming from a CS background, I'm accustomed to mapping problems to relational data. Everything can be stored in an RDBMS.

However, I often work in a one man band, and need to push out production ready system in weeks. In these cases, as a compromise, I choose a managed NoSQL database as it requires less code and DevOps work to be up and running. It's not ideal.
