Current, we have a tracking system that uses SQL Server 2012 database. None of the tables in the database are indexed. I believe if index is applied for those tables, the performance should improve.
In order to impress my boss with this idea, I would like to be able to generate a BEFORE and AFTER indexing performance report.
Is it a must that I have to select one or a few specific queries from our tracking system program and use them as the benchmark? Or I can just use some kind of data collector that collect certain performance data for say 1 week and then compare BEFORE index and AFTER index?
