Schema Federation

Schema federation is a method of combining multiple data sources, each with its own structure or schema, into a single, unified interface. Instead of copying or consolidating all data into one database, federation allows different systems to work together seamlessly, letting users query across all sources as if they were one. This approach maintains the independence of each data source while providing a cohesive view, enabling organizations to access and analyze diverse data efficiently without the need for extensive data migration or duplication.
