Universal Data Graph by Tyk is a solution for integrating existing services into a single endpoint. It allows users to stitch together disparate data from multiple sources into a single API using the Tyk UDG designer interface. Universal Data Graph transforms APIs into a single unified API with no new code, services, or infrastructure. It leverages the power of GraphQL, enabling users to define their schema, map data sources, and publish APIs after configuring the endpoint. Universal Data Graph supports REST, GraphQL, and Kafka data sources, and can transform GraphQL to REST if needed. It provides control, security, and governance, and can replace existing GraphQL gateways. Universal Data Graph enhances API aggregation, addressing over fetching and under fetching issues common in REST APIs. It enables quick and painless access to data without being locked into a single language or technology provider.
