Coherence SIG: Using Oracle Coherence to Enable Database Partitioning and DC Level Fault Tolerance

Today I was speaking at Coherence SIG in New York.
Update: 21 July I was speaking in BA Coherence SIG, slide deck is slightly updated
Partitioning is a very powerful technique for scaling database centric applications. One tricky part of partitioned architecture is routing of requests to the right database. The routing layer (routing table) should know the right database instance for each attribute which may be used for routing (e.g. account id, login, email, etc): it should be fast, it should fault tolerant and it should scale. All the above makes Oracle Coherence a natural choice for implementing such routing tables in partitioned architectures. This presentation will cover synchronization of the grid with multiple databases, conflict resolution, cross cluster replication and other aspects related to implementing robust partitioned architecture.

4 levels of replication technologies

Esse about state of art in replication technologies.
Replication is widely used to achieve various goals in information systems, such as better performance, fault tolerance, backup, etc. Four classes of replication technologies are available. Your decision about which technology to use will depend on the logical presentation of the data you are trying to replicate.
