How can one article help you find others?
How can you figure out which databases are likely to include your starting article? Use Ulrich's International Periodicals Directory to look up the journal in which the article was published. When looking at Ulrich's detailed information about a specific journal, select the tab for Abstracting & Indexing to see a list of the databases which cover that journal, then consult with a UCF librarian to see if the UCF Libraries subscribe to any of those databases.
Specialized vocabularies -- The index terms and descriptors vary between databases. A specialized database may use several index terms to focus on detailed subtopics. A general database or a specialized database for a related discipline may use a more general term to group your topic with similar concepts.
