This document describes how to create a relational database in Microsoft Access with two tables - a Courses table and a Sections table - linked in a one-to-many relationship. It initializes a new database, designs the tables, adds sample data, links the tables, and demonstrates what happens when records are updated, modified, and deleted with and without enforcing referential integrity and cascade options. The key aspects of referential integrity and how it ensures consistency between related tables are explored through examples of adding, modifying, and deleting records with various configuration settings.
