An Entity Relationship Diagram (ERD) is used to illustrate the various entities and their relationships in a laboratory assistant's workplace. It provides a graphical representation of the connections between different entities, such as student assistants, supervisors, laboratories, tasks, and equipment. This diagram helps visualize how different personnel and elements interact with each other within the laboratory setting. As illustrated here, the entities can be products, customers, transaction reports, payments, deliveries, and such. Create a similar design using the free templates and symbols provided by EdrawMax.
