|Specific characteristics||Oracle NoSQL Database is a scalable, distributed NoSQL database, designed to provide highly reliable, flexible, always-on data management across ac onfigurable set of storage nodes. Oracle NoSQL Database was named a leader in the Forrester Wave TM : Big Data NoSQL, Q3, 2016 .|
Data can be modeled as relational-database-style tables, JSON documents, RDF Triples or key-value pairs. Oracle NoSQL Database is a sharded (shared-nothing) system which distributes the data uniformly across the multiple shards in the cluster, based on the hashed value of the primary key. Within each shard, storage nodes are replicated to ensure high availability, rapid failover in the event of a node failure and optimal load balancing of queries. NoSQL Database provides Java, C, Python and node.js drivers and a REST API to simplify application development. NoSQL Database is integrated with a wide variety of related Oracle and open source applications in order to simplify and streamline the development and deployment of modern big data applications. NoSQL Database is dual-licensed and available as an open-source Community Edition as well as a commercially licensed Enterprise Edition.
Oracle NoSQL Database can be integrated with a number of Oracle and Open source products for enterprises that rely on various databases for their most critical business data.
