Exchange Server is the backend of email application used by Exchange. Small and Medium enterprises using Exchange server communicate via emails.

Log files in Exchange Database are the most important one. These files hold the record for each and every action performed on a database. Log files will contain the information and query performed on the server with date, time, data on which it is executed. Inserting/ Updating/ Deleting all the files get stored on the server. So, if we know the last action from where the database gets corrupt the action can be rolled back to recover files.
When the activity on the transaction is in log files and the database is closed after the query is executed then it terms to clean shutdown and database said to be in a consistent state.
But if the database is shut down before the transaction in log files is not executed it said to be as dirty shutdown and database goes to the inconsistent state.
