Diagrams
On this page
A project's Mapping screen maintains entity-relationship diagrams that show tables, foreign key relationships, and data types. This helps you optimize how you represent your relational data in MongoDB. Diagrams also let you see how your mapping rules shape your MongoDB schema.
When you finish creating a migration project, Relational Migrator creates a new diagram based on your mapping rules.
Each diagram has two views:
The Relational view represents the tables in your relational database. This view updates if you change your project's data model.
The MongoDB view represents the collections in your MongoDB database. This view updates if you change your project's mapping rules.
You can also use Hackolade to visualize your schemas.
Hackolade is a visual data modeling tool. You can explore schemas in Hackolade by importing a Relational Migrator .relmig file. For details, see the Hackolade help article.
