Final answer:
In an ERD, the tables labeled as Customer Info store customer-related data, while the control tables are used to manage and control the system.
Step-by-step explanation:
In an ERD (Entity Relationship Diagram), the tables labeled as Customer Info contain information related to the customers. These tables typically hold data such as customer names, contact details, addresses, and other personal information. On the other hand, the tables labeled as control tables are used to manage and control various aspects of the system, such as settings, configurations, or reference data.
Both the Customer Info tables and the control tables play important roles in the overall functioning of the system. However, their purposes and the type of data they store differ. The Customer Info tables are mainly focused on storing customer-related data, while the control tables are designed to store data that helps control the system and its behavior.
The switch between the two types of tables when answering the question above is done to provide a clear distinction between the two and to explain their respective purposes and roles within an ERD.
