I'm talking as a whole. So yes, there are cases where it's not relational but on average most data is relational. A user has many projects. Those projects have many tasks. This is very common to most web-based software used today. Think of all the tools out there that work perfectly with this structure. Most of our data isn't files, docs, directories. It's data given to us by our users or generated by our own processes. I'm not getting the reference to CSVs and word docs. Yes, we store uploaded files but the metadata is stored in the database in a row that has some identifier that links to the directory where the file is stored. That works fine. We don't need a document database.
