Use EdrawMax or EdrawMax Online to create the cargo system entity-relationship (ER) diagram. The graphic designing tool provides all the appropriate tools to make the ER diagrams. The cargo system refers to goods or products transported from one place to another -- water, air, or land. Though cargo means all goods on board a transport vehicle, it does not include items such as personnel bags, interests in the storage, equipment, or products to support the transport carried onboard. As shown in the below image, the cargo system entity-relationship diagram has several activities and relationships among the attributes like a person, time, alternative, occupation, and others.
