What is an ER Diagram and Used For?

In any database, there are two types of data we observe, 1. Object or Entity and 2. Attribute. An object can be anything, any real-world entity, and the attribute data are the properties of the object that describes the entity. The diagram that represents various objects with their attributes and how the entities are related to each other is known as ER Diagrams.

In complex business processes, when we try to create, design, formulate or analyze database, an ER Diagram helps to do that for better understanding of the entire process and the whole structure. It can be helpful in finding out if there has been any drawback in the model. So, we can say that ER Diagrams help troubleshoot a business workflow and analyze which entity is related to which and how they are connected. That is the reason, organizations that deal with sophisticated data management use ER Diagram Tools to find out loopholes in database.

Let’s find out some of the top ERD diagram tools available in the market using which you can quickly illustrate the logical structure of the database.
