Entity Relationship Diagrams are really helpful, but it is essential to know all their components, symbols, and meaning of these symbols before you can use them. So, here we will discuss the three main components of an ER diagram and their shapes and relationships.

These three components form the basis of every Entity-Relationship diagram, and an ERD would be incomplete if any one of them is missing. The most significant component of an ER diagram is its entities. Since an ERD represents the structure of a database, the entities are the tables that the database is composed of. Entities are nouns, such as concepts, locations, products, roles, events, and things.

Now, the critical thing is to understand that different notations have different symbols. After entities, the second component is the relationships between the entities. These relationships show what the associations between the different entities are. Usually, these relationships are depicted by verbs. After relationships, the next part is the attributes of the entities. As an entity is the table of a database, its attributes are the facts that describe the table. With it, you can access hundreds of templates including ERDs allowing you to instantly create a structure of your database.

In addition, you can create as many diagrams are required without even bothering about expiration. On top of that, exporting diagrams to images with no watermark could be done through this ER diagram maker. Next on the list is Draw. This is a web-based tool that allows you to create entity relationship diagrams without registration required. At first, the tool asks the user to specify the location where to save the diagrams.

You may keep your files on Google Drive, Dropbox, or on your computer hard drive. Another key thing to remember about this free ER diagram tool is that you can choose your preferred language when using the tool.

Over and above, you may continue editing diagrams to integrated productivity programs like Jira and Confluence. Visualize your database structure in a relational and logical way with the help of Lucidchart ER diagram maker.
