In an ER diagram, which elements are commonly represented?

ER diagrams illustrate the data structure by showing the things we store information about (entities), the details about those things (attributes), and how those things relate to each other (relationships). In this representation, entities are drawn as rectangles, attributes as fields, and relationships as lines connecting the entities. This combination helps you see what data exists and how different data types connect, such as how customers relate to orders. Other diagram types or conventions show tables with keys, data flows between processes, or storage shapes like cylinders, which are not the focus of ER diagrams.
