Eh, I am old enough to remember when SQL was the new kid on the block and received nothing but disdain from "database experts" as it was considered toy-like and not suitable for efficiency and large data sets. I distinctly recall meetings with DBAs where SQL (and the RDBMS platforms) were ridiculed as PC-weenie toys for kiddie boxes. That no way could accommodate mission critical enterprise production systems. Now, ~20 years later, it's the SQL advocates playing the same role as those grizzled old champions of mainframe fare hierarchical and VSAM-like structures.
