DOI stands for Digital Object Identifier. A DOI is used to show this is the same article no matter where you find it online. If the article has a DOI you are supposed to use it. References found using EBSCO databases (such as Academic Search Ultimate or Business Source Complete) will usually give you a DOI if there is one but ProQuest citations don’t.
Since articles written more than about five years ago don’t have DOIs, most professors do not insist on DOIs but let you use the alternatives outlined on Journal Articles (online) The link is below.
But if you are writing for publication, I would make every effort to see if there is a DOI for the article you cite. You can look up DOI here: Free DOI Lookup.
