There are several ways to manage ER diagram. ER or Entity Relationship diagrams provide a better understanding of the database design. In other words, it is a flow chart that represents entities like people, concepts, or objects, their relationship in a system. To manage ER diagram begin by first getting to know the entities. After identifying them, map out the related attributes of each entity. Next, join entities and attributes by coming up with the relation between them. Lastly, determine how much data will come out from each entity. Finally, have a run-through of your ER diagram and if everything looks good, save it. To manage ER diagram use symbols like boxes, ovals, circles, rectangles, diamonds, arrows, etc. There is no one way to manage ER diagram, rather several methods work. ER diagrams are used in the field of education, design database, debug database, research, etc.
