Multi-Model Database

A database that supports several data models, such as document, key-value, graph and column, behind one service.

Definition

Azure Cosmos DB is the classic example, with APIs for NoSQL, MongoDB, Cassandra, Gremlin, Table and PostgreSQL. Multi-model services reduce operational sprawl but each API has its own constraints.

Exam tip

On DP-900, Cosmos DB's API selection depends on the existing app or data model; for example, migrating MongoDB apps uses the MongoDB API.
