The Data Graph API allows you to use a single endpoint to access a broad range of data in the Precisely Data Catalog, while returning only the data you specify. Not only can you retrieve data from multiple datasets with one query, your query can traverse dataset relationships, so for each record you retrieve from a dataset, you can also retrieve related data from other datasets.
Data Graph is a GraphQL™ API. GraphQL is a trademark managed by the GraphQL Foundation. For more information, see https://graphql.org.
GraphQL looks at data as a graph consisting of "nodes" and "edges". Nodes are data objects. Edges are relationships between the data objects. The graph is defined by a schema. API requests specify which data they want to retrieve, and if applicable, which relationships to use to access related data.
