I agree that _normalized_ is a more precise term for what I'm describing, I only used relational because contemporary discourse seems to favor that term in these kinds of discussions and seems to imply a high degree of normalization.

I don't agree with this though. Nothing about a software architecture is _ever_ orthogonal to the domain.
Ah, you mean that if the data is in a normalized form. Relational data means, basically, data in tabular form. Tabular data can be normalized or not.

Assuming you are talking about data in normalized form, that's orthogonal to the domain. That's in fact the major breakthrough of relational databases–that data across domains can be modelled as relational and normalized.
Now, in the relatively rarer cases that you don't care about normalizing data, a stream can be useful. But in the vast majority of cases IMHO, we should be looking at a proper relational database like Postgres before thinking about streams.
