This episode breaks down relational database structure for the CompTIA IT Fundamentals (ITF+) certification exam. You’ll learn how data is organized into tables, with each table consisting of fields (columns) and records (rows). We’ll explain the roles of primary keys, which uniquely identify records, and foreign keys, which establish relationships between tables.
We’ll also explore constraints that enforce data accuracy, such as requiring values to be unique or non-empty. Mastering these relational concepts will prepare you for questions involving database design and query interpretation. Produced by BareMetalCyber.com.
