SQL Server Transaction Log Management
Penulis: Tony Davis and Gail Shaw •
Identifier: --tonydavisa-1653
Associated with every SQL Server database is a primary data file (.mdf), possibly some secondary data files (.ndf), and a transaction log file (.ldf). The purpose of the data files is self-explanatory, but the purpose of the log file remains, for many, shrouded in mystery, and yet it is critical to the everyday operation of SQL Server, and to its ability to recover a database in the event of failure.
