Here is an ER diagram (ERD) for car rental system. In this template, entities such as "Car," "Customer," "Rental," and "Billing" are represented by rectangles, with their attributes listed beneath. The relationships between entities are represented by lines or arrows, indicating the type of relationship (e.g., one-to-one, one-to-many, or many-to-many). It can serve as a valuable tool for designing and developing a car rental system.
