Enter multi-model databases, which combine multiple data models in a single system — allowing developers to store and query relational, document, graph, and key-value data simultaneously.
Why Multi-Model Databases Are Gaining Popularity
Flexibility: Handle multiple types of data without maintaining separate databases
Cost Efficiency: Reduce infrastructure overhead
Simplified Development: Unified query language and tools
Better Performance: Optimized for specific data types and access patterns
This allows businesses to respond faster to changing requirements and scale more effectively.
