Relational Databases
Each Data Entity is in a separate Table (e.g., employee, car, order header, order line item)
Table rows are related by “linking” columns-- primary and foreign keys (EmpID, OdrID)
Rules of Normalization—to avoid “anomolies, make more adaptable as change requests come in
Do not duplicate data (aside from key values)
Every field should pertain to the table’s subject
NO REPEATING GROUPS!! (Hobby1, Hobby2)
