Oracle Releases NoSQL Databases

 

 

Oracle, as the world's largest relational Database provider, has also joined the NoSQL Database chain in its product chain. In addition, this new Database name is so domineering that it is called NoSQL Database, I think of a joke about Sina Weibo's changing weibo.com Domain Name:

Three family members made bread, three family members named three cards of bread, four family members named four family members, and five family members named five family members. One day, the three breads were renamed. Li Si, Wang and Wu, said in the same voice: I will wipe it!

Oracle's NoSQL Database is one of the components of the Big Data Appliance released on Oracle's global Daquan in October 4, big Data Appliance is a system that integrates Hadoop, NoSQL Database, Oracle Database Hadoop adapter, Oracle Database Hadoop loader, and R language.

The following is a brief introduction to the features of NoSQL databases:

• Simple data model
  • Key-Value storage, where key consists of primary key and secondary key
  • Written in Java and supports Put, Delete, and GET operations based on Java APIs.
• High scalability
  • Supports automatic hash function-based data sharding policies
  • Provides Intelligent Control Based on the Data Node topology and access latency to provide the best data access performance.
• Behavior predictability
  • Provides ACID transaction support and supports transaction-level settings based on global and single operations.
  • A Cache layer composed of B-tree data structures and an efficient query scheduling mechanism provide controllable request latency
• High Availability
  • No spof
  • Provides a built-in and configurable data replication and backup mechanism.
  • Good fault tolerance for single point or multiple points of failure
  • Provides disaster recovery for data through data backup across data centers
• Simple Management and Maintenance
  • In addition to command lines, it also provides Web-based interface management tools
  • Provides control over the system and data nodes
  • Allows you to view the system topology, system status parameters, current load conditions, request latency records, internal events, and notifications.
