Firebase Data Connect Schema defines the structure and relationships of data used by Firebase Data Connect, a service that enables secure and scalable access to relational data from Firebase applications. It specifies how data is organized, queried, and synchronized between Firebase and connected databases, ensuring consistency and efficient data operations.
