SQL Server DataBase Synchronization

Is the SQL Server synchronized to be compatible with many processes? Do i have to make synchronization to be possible to work with D开发者_开发技巧ataBases so that more than 1 process be used at the same time?

Sql Server is designed to handle multiple processes working on the same data simultaneously (via various lock mechanisms etc). You can also control the level of synchronization / isolation via SET TRANSACTION ISOLATION statement. ( http://msdn.microsoft.com/en-us/library/ms173763.aspx )

SQL Server will manage the synchronization for you. See database transactions and isolation levels for more details.

I depends on what you need. If all your processes are reading from the database - than you can ignore the concurrency altogether. If you have complex write operations, which need to execute multiple queries, and you wish them to be atomic - look into transactions (or if your application allows it try to execute them from a single process).
