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, Business Source Premier, Expanded Academic ASAP, JSTOR, PsycINFO, Education Full Text, Library Literature & Information Science Full Text and so on that are offered through the Library.

Example:
Ramchandani, P., Wiggs, L., & Stores, G. (2000). A systematic review of treatments for
settling problems and night waking in young children. BMJ: British Medical Journal,
320 (7229), 209-213. Retrieved January 11, 2007, from Academic Search Premier
