DOI stands for "digital object identifier" that most recent, but not all, journal articles have. They are located on the "Detailed Record" page of a search result or on the article itself. If the article doesn't have a DOI, simply put "Retrieved from the Database Name database" at the end of the citation.
Here's an example of an APA citation with a DOI:
Silingiene, V., & Stukaite, D. (2014). Transformation of female leadership in terms of changes in leadership competency. Economics & Management, 19(1), 109-119. doi:10.5755/j01.em.19.1.5732
