Export MongoDB Database Schema

MongoDB Export Database Schema Tutorial

Analyzing the Schema

To begin exporting your schema, select the desired collection within MongoDB Compass and click on the schema tab to analyze it. Compass will sample a random subset of documents to determine the schema.

Exporting the Schema

Once analyzed, click the collection dropdown in the top menu bar and choose 'Share Schema as JSON'. This will copy the schema of your collection to your clipboard in a JSON format, which includes details such as name, path, count, types, and values for each field.

Understanding the Exported Schema

The exported JSON object reflects the schema of a sampled document from the collection. It shows field details such as whether it is an object, an array, an ObjectID, or an undefined type. Fields like "_id" are ObjectIDs, while a unique string field "us" indicates no duplicates are allowed.

Using the Exported Schema

Exported schemas are ideal for sharing with your team or for comparing schemas across collections. They provide a comprehensive structure of your data, including unique identifiers and data types specific to each field.

Example Schema for a US Variant

The provided example schema represents a variant of "Soccer" in the US, showing how to interpret the fields and types within the exported schema.

Frequently Asked Questions

What does the MongoDB export schema feature do?

The export schema feature in MongoDB Compass allows you to share your schema, compare it with other schemas in different collections, and copies your schema to your clipboard as a JSON object.

How does MongoDB Compass analyze your schema?

Compass analyzes your schema using a random subset of documents.

What are the common field types found in a MongoDB schema?

Common field types in a MongoDB schema include ObjectID for the _id field, Array for the equipment field, and Document for the variants field.

What are some best practices for MongoDB schema design?

Best practices for MongoDB schema design include embedding data when appropriate, using $lookup for referencing data, and choosing between embedding and referencing based on what works best for the application. Additionally, arrays should not grow without bound, and data should be modeled based on the application's data access patterns.

What are the considerations for embedding vs. referencing data in a MongoDB schema?

When choosing between embedding and referencing data in MongoDB, consider key value pairs within the document for one-to-one relationships, embedding for one-to-few and one-to-many relationships, and referencing for one-to-squillions and many-to-many relationships. You should favor embedding unless there is a compelling reason not to, such as needing to access an object on its own.
