An Entity-Relationship (ER) diagram for a car showroom typically includes entities such as "Car," "Customer," "Salesperson," and "Transaction." The "Car" entity might have attributes like "CarID," "Make," "Model," and "Price." Relationships could include "Customer purchases Car," with a many-to-one relationship from "Transaction" to both "Car" and "Customer," indicating multiple transactions can involve different cars and customers. Additionally, "Salesperson" can be linked to "Transaction" to show which salesperson facilitated the sale.
