OrientDB
The first multi-model open-source NoSQL database combining graphs and documents.
OrientDB is a multi-model open-source NoSQL database management system that uniquely integrates the power of graph databases with the flexibility of document databases. It's designed to be a scalable, high-performance operational database that addresses the challenges of polyglot persistence by allowing multiple data models within a single system. This approach reduces operational complexity and helps maintain data consistency across different data types. This database is ideal for developers and organizations looking for a versatile and performant solution that can handle complex relationships and diverse data structures without the need for multiple specialized databases. Its architecture is engineered for speed, offering fast read and write operations, efficient RAM usage, and rapid traversal of graphs and trees, irrespective of database size. It aims to replace traditional relational DBMS for operational needs by providing enhanced functionality and flexibility.
