Object Oriented Database vs Relational Database

Fault Tolerance

Conventional RDBMS deal with fault tolerance issues and high data available with hardware based solutions. An example is the use of RAID technology to guard against media failure. These options are also available to an OODBMS.

OODBMS that are based on peer to peer technology are designed without any single point failures. These systems are setup to degrade gracefully. If part of the distributed information store is not available, then the remaining information may still be accessed. These systems are more resilient to catastrophic failures.

Some systems also offer additional protection by replicating important pieces of data across multiple compute nodes. In this situation, failure of a single node does not result in the loss of data that was replicated and therefore available on some other node.
