Questions tagged [multi-model-database]

Multi-model database integrates multiple data models (e.g. document, graph, and key-value) against a single, integrated backend. The data can be accessed by the same query language that covers all supported data models. This tag is used when the question involves the usage of one of those databases.

implements the polyglot persistence without using various databases. This approach provides better maintainability and also does not require the programmer's knowledge of multiple databases. Typically, these databases support key-value, document, and graph data models.

Examples of multi-model databases:

  • OrientDB
  • ArrangoDB
  • CosmosDB
