摘要

Computer systems all around the world are prone to attacks from malicious users. Prevention of attacks on systems, although not impossible, admittedly, is impractical. Hence, the next best thing to do would be to recover the database from an attack in a quick and efficient way. The log file stores the operations of the transactions and this information can be used to recover the database. Several approaches have been proposed to recover the database from an attack, like the transaction dependency approach, the data dependency approach to name a few. But these methods take up valuable system resources to do a significant amount of computation to build the log file while the operations of the transactions are still on. In this research, we propose alternate methods that use less time to build the log thus increasing the system through put. With the help of efficient algorithms, we can assess the damage in a quick and efficient way. This paper proposes two techniques to build the log based on certain factors; number of committed transactions and time.
