So let me ask this: what does the NSA use? (or the british equivalent).
That will convince me more than this ad.

The only thing new, again, is that we can ISAM (Indexed Sequential Access Method) and other database types (even SQL) is that we can fit much of, if not all of, the database in memory for now. Even fitting in much of the indices and a large subset of the database content (think super-cache) can markedly improve read-decision-write cycles.

All I knew back in the 70's and early 80's is knew again (pun intended). C'est la guerre.

Its community interprets 'NoSQL' as 'Not Only SQL'

SQL RDBMS databases are seen as a SubSet, not as an alternative.

It basically refers to all types of structure storage, INCLUDING the 'traditional' SQL-RDBMS systems.

Is it just me?
