The entity integrity rule states that each entity must have a unique identifier, in this case, each customer must be identified by a unique customer number. This ensures that there are no duplicate records and allows for efficient data retrieval and analysis. The referential integrity rule pertains to relationships between tables and is not relevant to this scenario. Insert and update anomalies occur when there are inconsistencies in the database that lead to errors during data entry or retrieval.
