According to the .NET framework design guidelines, they say DB is an acronym and cased as such. But I thought it was an abbreviation of database?

    It's definitely not an acronym. Acronyms are words you can pronouce, like LINQ or SOLID. – Matt Hamilton Aug 28 '09 at 05:09

    Matt Hamilton's comment is incorrect - the ability to pronounce acronyms does make one. People just try to form them so they do for because it's a memorization technique. – OMG Ponies Aug 28 '09 at 05:13

    An abbreviation is any commonly recognized shortening of a word - acronyms are special cases of abbreviations. See http://en.wikipedia.org/wiki/Abbreviation In any case, does it matter? – Charlie Salts Aug 28 '09 at 05:35

    @Charlie: the question is pretty terse but, based on the tags, I'm guessing squi is getting FxCop warnings for some class/variable that contains "Db" in it. Still, this may be the most pedantic question ever: DB -- acronym or abbreviation? – Randy Levy Aug 28 '09 at 05:43

    Technically Matt is correct. DB is an initialism. To qualify as an acronym it should be pronounceable as a word. "dee bee" is not a word so DB is not an acronym. However this is another case where popular misusage is overruling the dictionaries. In the process we are losing what can be a helpful distinction. – APC Aug 28 '09 at 06:29

  • For a source on this question see the section _Capitalization Rules for Acronyms_ in http://msdn.microsoft.com/en-us/library/vstudio/ms229043(v=vs.100).aspx where is says "A property named DBRate is an example of a short acronym (DB) used as the first word of a Pascal-cased identifier." – Jeff Walker Code Ranger Dec 20 '14 at 01:30

Originally it was "data base", then "data-base", and then just "database". You can see all three used in this paper and its citations. Reference 4 is to E.F. Codd's 1974 paper "Recent Investigations in Relational Data Base Systems", reference 2 is to Don Chamberlin's "Relational Data-Base Management Systems" (1976), while reference 1 is to a paper in the ACM Transactions on Database Systems.

You see this sort of progression in English as a new compound noun becomes familiar. Take a look at Google Books and type in "sky-scraper" to find century old references to the new type of building.

So actually DB is an acronym for the old "data base". (It's not a portmanteau, which is a blending of two or more words, eg, "smog" is a portmanteau of "smoke-and-fog".)

  • Thanks for the great info! Given that dictionaries like www.m-w.com now contain "database" but not "data base". That was probably already the when the .NET framework was being written, so they should have considered it an abbreviation of "database". Just still seems strange. – Jeff Walker Code Ranger Dec 20 '14 at 01:39

Database is a portmanteau of "data" and "base"; that makes "DB" to be an acronym because it is the first letter of each word involved (even if the words are written as a combined word).

An abbreviation is usually the first few letters of the word IE: "abbrev." is the abbreviated version of "abbreviation".

English is strange.

I think you'll find that 'data base' used to be two words, and slowly got merged over time, to one. The general process for merging words is

  • Data Base
  • Data-Base
  • Database

In regards to the API, I think it's sometimes inconsistent anyway, so I wouldn't be too concerned with specific definitions. My preference is to always uppercase acronyms.

  • I was reading some paperback (paper back?) thriller from, like, 1996 in the loo a while back and the main character kept talking about the "data base" this and the "data base" that. I couldn't keep reading. – Rex Miller Aug 28 '09 at 05:24

I would say abbreviation instead of acronym as database is one word. Interestingly DB is already very overused dictionary.
