Multi-Model Database
A multi-model database is a database management system that supports multiple data models (e.g., document, graph, key-value, relational) within a single, integrated backend. It allows developers to store, query, and manage data using different models without needing separate database systems. This approach provides flexibility to handle diverse data types and access patterns in modern applications.
Developers should use multi-model databases when building applications that require handling varied data structures (like social networks with graph relationships and user profiles as documents) or when transitioning between models without data migration. They are ideal for polyglot persistence scenarios, reducing operational complexity by consolidating multiple databases into one system, which simplifies deployment and maintenance.
