This video corresponds to the unit 4 notes for a graduate database (dbms) course taught by Dr. Gary D. Boetticher at the University of Houston - Clear Lake (UHCL). The theme is relational database theory. This video focuses on functional dependencies by defining the term functionally determines. Next, the idea of logically implies is presented. Afterwards, the video presents the idea of "F-closure." Finally, there is a revised definition of a database key.
