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. |
