If the transaction log file (.ldf) in Microsoft SQL is too big, it can cause performance issues, eat up valuable disk space and consume resources when you back up.Therefore it's imperative to periodically maintain the database to keep the .ldf file under control. To reduce the .ldf file, you must do threethings:ortunately, SQL Management Studio offers a simple GUI to perform both those tasks. If you don't have SQL Management Studio, you can get it here. If you are not sure how big your database's .ldf file is, SQL Management studio will let you peek as well.

It allows all three so-called  concurrency phenomena , dirty reads, non-repeatable reads, and phantoms:aving introduced read uncommitted isolation as the weakest of the available isolation levels, you should be expecting it to offer even lower isolation guarantees than locking read committed (the next highest isolation level).
