An article says: "there are lots of options for logging data in SQL Server. The best one depends on what you need to do with the audit logs. Unless you really need them, I recommend against using log tables and triggers. Use the SQL Server log files and a log parser. If you carefully consider all your needs, and decide that a log table is the best way to do it, make sure to take into account the options you have about how and what to log.". Please kindly provide details on how to use the SQL Server log files and a log parser. Thanks.
