Yes, like most on this NG you say that RM+RA is for recording and
managing data, while OO is not. Unfortunately this view is
Consider the following
None of these areas appear to be handled particularly well with RM
+RA. Yet they all represent problem domains where data needs to be
recorded, persisted and managed.
* Source code
* CAD drawings
* Web pages
* Sound data
* Video data

My original post provides an insight as to why there are two types of data.
If you think RM is suitable for all data, why don't you represent the equivalent of SQL expressions relationally as well? Wouldn't that be nice! In fact don't stop there, each post to the NG should be nothing but a set of tables. That will fit with your view that all data is inherently relational. You should be able to suck the post into your favourite RDBMS, submit some queries and mine the data to find out everything you need to know.
In fact why stop there? Be bold and suggest that all digitally stored data in the world, including all web pages, music, video and source code be represented at the logical level using relations. That way we get all the power of RA and what more could you want? That nasty, ill-defined OO thingy can be regarded as a mere and trivial concern for the "physical layer", and something for the grunts to worry about.
