Exciting news is brewing in the Notion universe! If you’re a power user, developer, or just someone who relies on Notion for robust data management, you might have caught wind of an upcoming structural overhaul to its databases. An email from Make, a popular automation platform, hinted at these changes, and a deeper dive into Notion's developer resources confirms a significant evolution: support for multiple data sources under a single database container.

This isn't just a minor tweak; it's a fundamental shift in how Notion structures and organizes information, promising greater flexibility and potentially a cleaner workspace. Let’s break down what these changes mean for your Notion setup and any third-party integrations you rely on.

Key Takeaways

  • Notion databases are evolving from single tables to flexible containers for one or more "data sources."
  • A "data source" is the new term for what a Notion database used to be: a single table with its own unique set of properties.
  • This update introduces an additional organizational layer, allowing for more granular control over property sets within a single, unified database view.
  • Third-party integrations utilizing the Notion API will need to update to recognize new "data source IDs" for databases with multiple sources.
  • Crucially, existing integrations will continue to function for databases containing only a single data source, but adding new data sources to critical databases should be deferred until integrations are updated.

Notion's Database Transformation: Before and After

To truly grasp the impact of this update, it’s helpful to visualize the change in Notion’s internal hierarchy. Previously, a database was synonymous with a single table and its associated properties. Now, that definition expands significantly.

Feature Before (Old Structure) After (New Structure)
Definition of "Database" A single table with one unique set of properties. A container for one or multiple "data sources."
Properties One database = one set of properties. One "data source" = one set of properties.
Creation for Different Property Sets Required creating a whole new database for each distinct set of properties. Multiple data sources, each with unique properties, can reside within a single "database" container.
Example Setup
  • 1 Personal Project Database
  • 1 Client Project Database
  • 1 Project Database (container):
    • Data Source A: Personal Projects
    • Data Source B: Client Projects

Understanding the New Organizational Layer

The core of this update is the introduction of an additional layer to Notion's organizational hierarchy. Where before a database *was* the table, it now *contains* the table, which is now referred to as a "data source."

Think of a database as a folder, and each data source as a document within that folder. Each "document" (data source) can have its own specific template and properties, yet they all live under one umbrella "folder" (database). This means you could have a "Clients & Projects" database, and within it, one data source for "Client Accounts" with properties like 'Client Name,' 'Industry,' 'Contact Person,' and another data source for "Project Tasks" with properties like 'Task Name,' 'Due Date,' 'Assigned To,' 'Status,' and 'Associated Client.' This newfound distinction allows for a cleaner, more consolidated approach to managing related but structurally distinct information.

Enhanced Flexibility and Views

One of the most immediate benefits of this change is the enhanced flexibility in how you view and interact with your data. Currently, if you want different views of separate databases on the same page, you often use "linked database views" on different pages or struggle with limited display options. With the new structure, a single database container will be able to host different views, each accessing a different internal data source.

This means your "Project Database" could have a view displaying your "Personal Projects" data source, and another view on the same page (or even tab within the database) displaying your "Client Projects" data source. This significantly streamlines navigation and allows for more dynamic, context-aware dashboards directly within a single database page.

Navigating Relations in the New Structure

For those worried about how this affects interconnected data, rest assured: the fundamental mechanism for connecting different pieces of information remains largely the same. A database (container) does not automatically connect data sources with each other. If you need to link a "Client Projects" data source to a "Client Contacts" data source, you will still need to set up a relation property between them, just as you would between two separate databases today. This ensures that the robust relational capabilities Notion is known for remain intact and logical within the new framework.

Critical Update for Third-Party Integrations and the Notion API

This architectural shift has significant implications for third-party tools and custom workflows that interact with your Notion workspace via the API. Previously, integrations targeted a 'database ID' to access a specific table. Moving forward, these integrations will need to update to target a 'data source ID' when dealing with databases that contain multiple sources.

Notion has provided detailed upgrade guides and a changelog for developers, indicating a clear path for adaptation. It's crucial to note that existing integrations with the Notion API will continue to work as before for Notion databases that have only a single data source. This is excellent news, as it means you won't experience immediate disruptions for your existing, simple database setups.

However, a significant word of caution: if you are using any third-party integration that accesses your Notion workspace via the API (e.g., Make, Zapier, custom scripts), **make sure to not add any new data sources to critical databases until your integration or tool has updated to fit the new API changes.** Adding a second data source to an existing database before your integration is ready could break workflows, as the integration might still be looking for a database ID that no longer points to the specific table it expects. This concept of API versioning and schema evolution is common in software development, and developers will need to adapt their code accordingly.

FAQ

What is the main difference between a Notion "database" and a "data source" after this update?
After the update, a Notion "database" becomes a container that can hold one or more "data sources." A "data source" is the new term for what was previously called a database—a single table with its own unique set of properties.
Will my existing Notion databases stop working after this change?
No, existing Notion databases that contain only a single table will continue to function as they do now. They will simply be reclassified internally as a database containing one data source.
Do relations between data sources work differently in the new setup?
The process for setting up relations remains the same. A database container does not automatically connect its data sources; you will still need to create a relation property between specific data sources to link them, just as you would between two separate databases today.
How will this affect third-party automation tools like Make or Zapier?
Third-party integrations will need to update to account for the new "data source ID" if they access databases that contain multiple data sources. While integrations will continue to work for single-data-source databases, adding additional data sources to an existing database before the integration is updated may cause workflows to break.
When will these changes be rolled out to all Notion users?
While Notion's developer documentation indicates an upgrade guide for 2025-09-03, the specific rollout schedule for all users to see these changes in their workspace varies. It's advisable to monitor official Notion announcements for the exact timeline.

Conclusion

Notion’s upcoming database update marks a significant step forward in its evolution as a versatile workspace tool. By introducing the concept of data sources within a database container, Notion is providing users with unprecedented flexibility in organizing complex information. This new organizational layer promises cleaner dashboards, more logical data structuring, and a more powerful platform overall. While there's a learning curve and a crucial period of adaptation for developers and users of third-party integrations, the long-term benefits of this enhanced hierarchy are clear. Stay informed, exercise caution with your critical integrations, and prepare to unlock a more organized and efficient Notion experience.
