Study Notes

ARIES Algorithm Overview

ARIES (Algorithms for Recovery and Isolation Exploiting Semantics) is used for database transaction recovery

Writing Approach

ARIES uses a log-based approach for writing, which means it maintains a log of all changes made to the database

Redo Recovery

Repeating history during redo means re-executing the transactions that were committed before the crash to bring the database back to a consistent state

Crash Recovery

Uncommitted transactions at the time of the crash are rolled back to their previous state during ARIES recovery

ARIES Recovery Procedure

The three main steps of the ARIES recovery procedure are: analysis, redo, and undo
