What is a Data Federation?

Data federation is the process of combining data from multiple sources into a single virtual view, without the need to physically move or replicate the data. This allows organizations to access and analyze data from disparate sources in a more efficient and streamlined manner, without the need to manually integrate data from each individual source. Data federation is especially useful for organizations that have a large number of data sources, where traditional data integration methods can be time-consuming and resource-intensive.

There are two main approaches to data federation: query federation and schema federation. Query federation involves federating queries across multiple data sources, while schema federation involves federating data schemas across multiple data sources. Query federation allows users to access data from multiple sources as if it were stored in a single location, while schema federation allows users to access data from multiple sources using a single schema.

More comprehensive insights

One of the benefits of data federation is that it can help organizations to better manage their data and gain insights from multiple sources. For example, a retailer may use data federation to combine data from multiple sources, such as sales data, inventory data, and customer data, into a single virtual view. This allows the retailer to gain a better understanding of customer behavior, inventory levels, and sales trends, which can be used to optimize operations and drive revenue.

Improve security and compliance

Another benefit of data federation is that it can help organizations to improve data security and compliance. By maintaining data in its original location and using data federation to access it, organizations can ensure that sensitive data remains secure and is not exposed to unauthorized access or breaches. Additionally, data federation can help organizations to comply with regulations such as GDPR, by providing a centralized view of data that can be easily managed and audited.


In conclusion, data federation is a powerful tool for organizations that need to access and analyze data from multiple sources. With the Macrometa Global Data Mesh, you can use the data model that makes the most sense for your application and make it available locally, globally, or both. One key advantage of the multi-model approach is that you don’t have to worry about time-consuming data integrations or storage maintenance. You simply use different databases at the same endpoint - so it is much easier to integrate different data streams into an application.
