You have learned some database components such as entities (tables) with attributes (columns/fields) and keys in previous lessons such as Relational Databases, Database Fields and Field Specifications, and Establishing Keys. Now based on the examples in those lessons, you will design a database for CTU, which includes three entities (tables): Students, Faculty, and Classes. Note a class refers to a particular class section. For example, the current CS253 you are taking is one class instance (i.e. CS253-01), and another CS253...
