Oracle Link

SQL Server is the best RDBMS, at least according to the current thinking at SQLServerCentral.com, and is fully capable of meeting all of your database needs. However not all database systems run on SQL Server and it seems that we often see data from some other system being consolidated on SQL Server for additional processing or reporting.

You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.
