You can customize the transaction isolation level based on your SQL Server, which will meet your requirements or improve performance. For example, for SQL Server with simple logic, you can use the read uncommitted mode to reduce deadlocks, reduce congestion, and improve performance and response. There should be a lot of such application scenarios, but there is no

When doing a project to get a only 280M database backup, but in SQL Server 2000 recovery when waiting for a long time did not recover complete, it is incredible, so suspect there is something fishy. To the data file directory next look, sure enough to claim a close to 10G database log files! Databases that have never done so much data before, and have not done a database with 3 of years of database logging.

when using SQL Server High availability features, for example,the XenDesktop site database uses the full transaction logging mode to run database mirroring. transaction logs that run through the full transaction logging mode grow too large until the database space is filled or the
