Key benefits

A picture is worth a thousand words.

Blueprint to your own product: A diagram can give you a clear model of your data structure and help you recognize errors. It's like a blueprint to your house. You know what you are building, how to connect the pieces and you have the necessary documentation.

Efficient communication: It allows all your team members or clients to understand the relations among collections and documents in an effective manner.

Faster development: Draw data models and generate code. Avoid typos, make changes quickly.
