Finding a better candidate for your clustered indexes

When creating tables it is difficult to determine exactly how the data will be accessed. Therefore when clustered indexes are chosen they are often just the ID column that makes the row unique. This may be a good choice, but once the application has been used and data access statistics are available you may need to go back and make some adjustments to your tables to ensure your clustered indexes are providing a benefit and not a drain on your applications.
