Today SQLServerCentral.com (SSC) had published my article that introduces the Transaction Log. The primary purpose of this article was to help the newer DBAs understand how the transaction log works, and to clarify some commonly misunderstood parts of maintaining the transaction log.
This article covers a very broad and general introduction; including how the log is filled by SQL Server, easy to follow analogies to help grasp how transaction logs work with SQL Server, and some Good Practices to use when Transaction Logs are in use by SQL Server.
