I saw the word database today with a hyphen in it ("data-base"), and it got me thinking: who coined the term "database", and where the heck did that suffix -base come from? These days we see it all over. It's used to imply database-like behavior, because it was lifted from database. For example: knowledgebase, infobase, videobase, metabase, sportbase, imagebase, and so on.

But whoever coined "database", why did they choose -base as a root? What did it mean then?

Update: a helpful reader (thanks, Ken!) sent along the Oxford English Dictionary entry for database:

1. A structured collection of data held in computer storage; esp. one that incorporates software to make it accessible in a variety of ways; transf., any large collection of information.
