sql why is transaction logs important
A transaction log is a file â integral part of every SQL Server database. It contains log records produced during the logging process in a SQL Server database. The transaction log is the most important component of a SQL Server database when it comes to the disaster recovery â however, it must be uncorrupted.After each database modification â transaction occurrence, a log record is written to the transaction log.All the changes are written sequentially. transaction log stores every transaction made to a SQL Server database, except some which are minimally logged like BULK IMPORT or SELECT INTO. Internally it is split into the smaller parts called Virtual Log Files (VLFs).
