Nerval's Lobster writes "For the past 40-some years, relational databases have ruled the data world. Relational models first appeared in the early 1970s thanks to the research of computer science pioneers such as E.F. Codd. Early versions of SQL-like languages were also developed in the early 70s, with modern SQL appearing in the late 1970s, and becoming popular by the mid-1980s. For the past couple of years, the Internets have been filled with heated arguments regarding SQL vs NoSQL. But is the fight even legitimate? NoSQL databases have grown up a bit (and some, such as Google's BigTable, are now mature) and prove themselves worthy. And yet the fight continues. Tech writer (and programmer) Jeff Cogswell examines both sides from a programming perspective."
