Multi-model databases support different NoSQL data models at once, typically a combination of relational, key-value, document, and graph models. Their expected benefits include increased versatility, reduced installation complexity, improved database performance, and smaller storage footprint. However, these benefits are insufficiently investigated, and current studies lack a comparison between multi-model databases and equivalent polyglot database architectures, i.e. setups that combine different technologies to accomplish the same functionality.
