Database modeling made simple with new ER diagram templates in Miro

You might already know that Miro is an intuitive workspace where you and your team can collaborate on work from end to end — from brainstorming and designing to iterating and delivery. But did you know you can also use Miro to build ERD diagrams? In this post, we’ll explore several ready-made ERD templates in Miro that will kickstart your database design process, facilitate effective communication, and ensure data consistency across your organization.

What are Entity Relationship Diagrams?

If you’re a database architect, engineer, or anyone involved in database modeling, you’re likely already familiar with Entity Relationship Diagrams (ERDs). If that’s the case, go ahead and jump to the templates below.

As a recap, these visualizations show the different entities (like objects or concepts) stored in a database, their types, and the relationships between them. ERDs depict how the different entities work together, helping users to pinpoint any gaps in the design.

For example, in a database for an online library , you might have entities like “Book,” “Author,” and “Member,” with relationships like “an Author writes one or more Books” and “a Member can borrow many Books.” ERDs use simple shapes and lines to depict these connections, making it easier to understand the structure of data before building the actual database. 

But building ER diagrams can take hours, which is why you need a tool to help you create them efficiently. Even better if you can work with your team to build the diagrams together. That’s why Miro’s collaborative visual workspace is the perfect canvas. Miro also offers crow’s foot notation, in which symbols at either end of the line describe the cardinality of the relationship between the entities.

How to build ERDs in Miro

There are a few ways to build ERDs quickly in Miro:

  1. Automatically generate ERD diagrams with Miro Assist or use ERD shape packs to get started from scratch. 
  2. Take advantage of Miro Marketplace apps such as Mermaid.
  3. Or you can use one of our templates

In this case, let’s focus on templates. With a template, you can add an example of an entity relationship diagram to your Miro board with just a few clicks, then collaborate with your team to customize the diagram, reviewing everything together in one workspace. 

If you’re working from a Miro board, you can choose the template you want via the template picker. Or you can browse different kinds of ERD diagram templates in the template library or via the user-generated template gallery, Miroverse. Miroverse has thousands of templates built by Miro users, including hundreds dedicated to diagramming. 

Whatever method you choose in Miro, your team can rapidly create professional ERD diagrams that can be tailored to fit your specific requirements. Plus, since each Miro boards is a living document, your ERD diagram becomes a centralized place where every stakeholder can brainstorm designs together, leave feedback, and always find the latest version.
