According to the APA, the name of the database does not have to be included in the citation of an article from a database. They attribute it to the fact that databases may change over time (p. 192).
APA also does not require for the retrieval date to be used, since there is very little chance that information contained in academic journal articles will change over time.
Author Last Name, First Initial. Second Initial. (Year). Article title: Subtitle. Journal Title,Volume(issue), page range. doi:xx.xxxxxxxxxxRetrieved from URL of journal home page [if available].
Some databases are great resources for reference and sourcebook information. Many times, these kinds of articles will not have a specific author. In that case, use either the database publisher or the company responsible for the information as author.
Some of these entries will also lack a date of publication. Instead of omitting the field altogether, APA requires that n.d. (for no date) to be entered in the parentheses.
Database publisher. (Year, if not known put n.d.). Title of specific document. Publisher. Retrieved date from URL database homepage.
