[ADR] Database technology (and hosting)

[piotrczyz]

Before you write, please be familiar with description of ADL

Context

• architectural drivers, business cases

Reng: I support a document database since I don't think referential integrity is a big issue here (some of the things we modelled can be nested objects, which then takes care of this integrity). However, if there is a good case for SQL, that's fine too. With regard to hosting, preferably something main stream that can be purchased / managed via the big cloud providers. When modelling data make sure that only things that really are part of the object are nested there (e.g. a relationship probably shouldn't be nested since it is shared by two objects -- unless it was duplicated).
