Uncompelling argument

Your argument conveniently ignores all the banking applications that *do* use traditional RDBMS applications on Tandem, Oracle, and DB2.

Also, I think you overlook the importance of query optimization as a driver for RDBMS usage. If you are going to argue that RDBMS does not scale, I think you need to define exactly what sort of scaling you are talking about. As much as people tend to diss SQL, RDBMS engines perform exceedingly well for a very large set of queries, especially on systems where data characteristics (e.g., cardinality) and the underlying data model change over time. That includes RDBMS implementations with all the well-known overhead of transactions.
