Then there exists a number in ab such that The idea behind the Intermediate Value Theorem is When we have two points af and bf connected by a continuous curve The curve is the function which is Continuous on the interval ab and is a numb ACID vs. BASE. ACID Properties:. Failures. Isolation Failure:. T. 1. transfers 10 from A to B. T. 2. transfers 10 from B to A. Combined, there are four actions:. T. 1. subtracts 10 from A.. T.

Replication Benefits. Replication enhances tolerance to failure. Performance can be improved in different ways. Placing replicas in the proximity of the process using them. Replicating servers and subsequently dividing the work among them.
