Separation and addition of MSSQL Server2000 database

If your database system is installed on a system disk (such as C disk), because C disk is vulnerable to viruses, you may want your data to be stored on a non-system disk (such as D disk), which is very simple, you do not need to reload the database, just "detach" the data, and then copy the relevant files to a directory in D disk, and then "append" Database can be.

SQL Server 2000 allows you to detach data and transaction log files from a database and then reattach it to the same or another server. Detaching a database deletes the database from SQL Server, but remains intact in the data and transaction log files that make up the database. These data and transaction log files can then be used to attach the database to any instance of SQL Server, which makes the database's usage state exactly the same as it was when it was detached.

Database separation and attach is actually very simple, even if you are first contact with the database, it is easy to do.
