-**OceanBase Database** is a distributed relational database. It is developed entirely by Ant Group. OceanBase Database is built on a common server cluster. Based on the [Paxos](https://lamport.azurewebsites.net/pubs/lamport-paxos.pdf) protocol and its distributed structure, OceanBase Database provides high availability and linear scalability. OceanBase Database is not dependent on specific hardware architectures.
