I\'ve seen a lot of people (http://blo

Answer 1

In CAP Theorem P is for Partition tolerance , which is the ability of system to handle partitions(partitions are isolated clusters - due to network failure or any other reason ..).

In a distributed network to handle a partition , system has to pick either Consistency or Availability.

In case of RDBMS there is no chance for partitions (assuming not distributed which is normal case) ,So Those will be always CA.
