What is an ER Diagram?

The entity relationship diagram is a high-level conceptual data modeling diagram. It helps with systematically analyzing and identifying data requirements needed for effective database designing.

How to Make an ER Diagram?

  • Choose your platform to create the ER diagram. Creately offers an intuitive interface for drawing ER diagrams online with use-case based ER diagram templates.
  • Once you open the Creately workspace, enable the ER diagram library. You can share the workspace with other key team members to collaborate with them as you identify all the entities in the system. An entity should appear only once in a particular diagram. Create rectangles for all entities and name them properly.
  • Then identify relationships between entities. Connect them using a line and add a diamond in the middle describing the relationship. With Plus Create, Creately intelligently suggests the set of next shapes you need to add, cutting back the time taken to manually drag and drop them to the canvas.
  • Add attributes for entities. Give meaningful attribute names so they can be understood easily.
  • Organize the ER diagram in a logical way to increase comprehension. Once completed, you can export it in PDF, PNG, JPEG or SVG formats to embed on other sites or share it with others.
