Locks can be applied on different levels of granularity—on entire tables, pages, or even on a per-row basis on tables. For indexes, it can either be on the entire index or on index leaves. The level of granularity to be used is defined on a per-database basis by the database administrator. While a fine-grained locking system allows more users to use the table or index simultaneously, it requires more resources, so it does not automatically yield higher performance.

Microsoft SQL Server 2005 includes a component named SQL CLR (“Common Language Runtime”) via which it integrates with .NET Framework. SQLOS provides deadlock detection and resolution services for .NET code as https://remotemode.net/ well.

While writing pages back to disc, asynchronous I/O is used whereby the I/O operation is done in a background thread so that other operations do not have to wait for the I/O operation to complete.
