In flight booking system, if the passenger booked the ticket, then it will remain booked despite of system crashes.This example shows the durability property of the database transaction.

Web services typically maintain three categories of data: shared data (accessible across all users/sessions), pre-session data (initialized before a session begins), and temporary data (exists only during a specific session or transaction).

This component of the RMAN environment is a copy of the primary database that is updated using archived logs created by the primary database.

During the execution phase, if more than one channel is allocated, then RMAN can execute certains commands in parallel so that all of the channel's target database sessions are concurrently executing an RPC call.

This classification of the degree of durability avoids the problem of lost transactions.

Here, a transaction commits as soon as it commit log record is written to stable storage at the primary site.

This RAID level is known as memory-style error correcting-code organization.

It is a block of RMAN job commands that is stored in the recovery catalog.

It includes archived redo logs and flashback logs.

This component of the RMAN environment contains the metadata that RMAN uses to perform its backup and recovery operations.

A transaction can lock a data item in exclusive mode only if it is not locked at all.

The node that originates the distributed transaction.

Here, the net server middleware is able to connect its pure java clients to many different databases.
