The instances are represented by the rows in relational tables.

I'm uncomfortable with the repeated focus on relational databases.

What about non-relational structures?

What about those single table, 2000 column RDBMS applications?

It's a messy world. 

Does any such thing as a non-relational database management system actually exist, bearing in mind data is represented using relations?

Circa., 2015, can we seriously allow SQL-RDBMS marketing-driven dogma turn the very notion of relations and database management on its head?

Relations represented as sets of Records in a Table isn't the only way to represent relations (that's SQL RDBMS dogma). You can also have them represented as Relational Predicate/Property Graphs (sets grouped by sentence predicate).
