Entity Relationship Diagram Template
Understand how the elements of your database interact with each other by using our entity relationship diagram (ERD) template.
About the Entity Relationship Diagram (ERD) Template
Explaining the ins and outs of a complex system is no easy feat — especially when you need to communicate with teammates, clients, or stakeholders. That’s where an entity relationship diagram (ERD) template can help. An ERD is a diagram that outlines how entities relate to each other within a complex system. Some examples include illustrating how information flows within a complex database design or depicting the different stages of a product delivery process.
In other words, an ERD helps you and your team better understand important yet complex concepts by presenting them in more digestible ways. And Miro’s ERD template allows you to kickstart the process of creating one.
How to use the entity relationship diagram (ERD) template
Ready to create an ER diagram? Scroll to the top of this page and click on the blue “Use template” button. That’ll take you straight to the template in Miro, allowing you to start editing it and making it your own. Once you’re there, here are four tips to make the most of the ERD template:
Step 1: Identify all entities in the system
An entity is anything that you can define, such as a person, concept, or object. Start by identifying what these are in your system and outlining them in the diagram. In the template, you’ll see five entities: customer, order, products, categories, and deliveries. To replace the existing text with your own, simply double-click to edit. Once you’ve identified all your entities, use the additional text boxes in each rectangle to add any supporting information.
Step 2: Identify relationships between entities
On the template, the connection lines between entities represent the relationships between them. To rearrange them, click on a connection line to reveal blue dots on each end of the line. Click on one of these dots and drag the end of the connection line to the entity you want it to lead to.
To add more connection lines, click on an entity to reveal blue dots around the rectangle, and click on one where you’d like to add a new line. You can also delete connection lines by clicking on them and hitting “Delete” on your keyboard.
Step 3: Customize your diagram
Time to truly make the ERD template your own. Add shapes, change colors, edit text, and use sticky notes to customize the overall look and feel. This step is especially helpful if you’d like your ER diagram to reflect your own brand style and colors. With Miro’s template, you can also upload your own files (such as documents and images) to further personalize and enhance your ER diagram.
Step 4: Share it with your team
Invite teammates to view your Miro board and leave comments by clicking on the blue “Share” button on the top right of your Miro board. Alternatively, you can also export your ER diagram as a PDF, image, and CSV.
Benefits of using an entity relationship diagram (ERD) template
There are various advantages to using Miro’s ER diagram template. On top of saving time from having to build one from scratch, you don’t have to create your diagram alone. Invite multiple collaborators to fill the ERD template with you in real time, or share it with them when you’re ready by inviting them to view it and leave comments.
And you’re not limited to using the pre-made shapes in the template. Miro makes it easy for you to add and remove elements from your template and even drag and drop your own files straight onto your Miro board. In other words, Miro’s ERD template makes it easy for anyone to create an ER diagram — even if they’re not familiar with the tool.
If you'd prefer to start from scratch when it comes to visualizing your database or system, Miro's diagramming capabilities make it the perfect ER diagram maker.
