PS people that care about ordering still use relational databases.
I think you mean that they use SQL databases. One of the major differences
between a SQL database and a relational database is in its approach to
ordering - in the relational model, columns are unordered but in SQL they
are ordered. If we're going to discuss angels on pinheads, we need
precision.
Agreed and a whole slew of issues derive from the fact that an SQL
database is not a faithful representation of the relational model.
