Adding a rebate table to accommodate discounts is an example of what?

• A. A data relationship
• B. A data model
• C. An entity-relationship
• D. A normalization process

Answer: (A)

Adding a rebate table to accommodate discounts illustrates a data relationship because it signifies how two or more entities relate to each other within a database. In this context, the rebate table serves as a means to establish a connection between products or sales transactions and the discounts that are applied to them. By creating this table, you are defining how discounts interact with other data elements in a structured manner. In contrast, a data model refers to the overall design or structure of how data is organized and how relationships among data entities are defined and managed. An entity-relationship focuses specifically on the relationship between distinct entities in a modeling context, such as customers, products, and discounts, but does not explicitly describe adjustments or additions like the rebate table itself. The normalization process involves restructuring data to reduce redundancy and improve data integrity, rather than simply adding new tables to accommodate specific functionalities like discounts.
