Citing an article you got full-text from an online database needs to have additional information at the end of the citation, which shows where you retrieved it. This is so that your professor or anyone who wants to track down the article you cited can know where to find it.
Online databases include ones such as Academic Search Premier, PubMed, CINAHL, PsycINFO, and so on that are offered through the Library.
The first part of the citation will be the same as what you would do for a print article. See the AMA citation page for journals for this part.
The second part of the citation includes information on where you found the article. There are two options for how to do this.

First Option
URL:
Give the web site address. End with a period. Ex. = http://proquest.umi.com/pqdweb?did=49294974&sid=1&Fmt=4&clientId=44142&RQT=309&VName=PQD.
Published or last updated date:
Give either the published date of the web site preceded by the word Published followed by the date or give the last updated date preceded by the word Updated and then followed by the date. End with a period. Ex. = Published January 22, 2000. or Updated May 25, 2007,
Date of access:
Date you accessed (viewed ) the page preceded by the word Accessed. End citation with a period. Ex. = Accessed September 24, 2007.
Second Option
Instead of giving the URL and published and accessed dates, you can just give the DOI (digital object identifier) instead. This number always starts with 10 and has a forward slash in it. You can find this number on the article's citation. Start with doi: and then give the number. End the citation with a period. Ex. = 10.1002/bmj6548.
