contrasing SPARQL Federation + DM/R2RML vs. SQL federation tools

I'm giving a talk at SemTech which I'm lead to believe will cover SPARQL over SQL databases. One of the motivators for the SemWeb is that we get to connect everything to everything, including e.g. sets of SQL DBs. The relational world has some tooling for the latter case, e.g. "Oracle Database Streams" and "SQL Server Integration Services". What do y'all know about them? It could help some audience members if I were able to contrast existing SQL tooling against SPARQL over DB-backed RDF graphs.
