If UTorID is a superkey, then so are {UTorID, name}, {UTorID, major}, and any other superset of {UTorID}. A relation can thus have a large nu ...

Database model
A database model is a type of data model that determines the logical structure of a database and fundamentally determines in which manner data can be stored, organized, and manipulated. The most popular example of a database model is the relational model, which uses a table-based format.
