Only in a simple one-vendor environment. If you are using more than one product, both may offer some same bit of functionality, and perhaps you cannot use them redundantly, but must choose one or other. In this case, the money you paid one of the vendors for the feature is already lost. You will presumably choose to use the one that either works best, or provides some side benefit.

Let me make it clearer. It should be clear and obvious that the simple bank+tellers OLTP benchmark in TPC-C can, and has been completely implemented with Oracle software. In that configuration, Oracle's features, proprietary or not, have been used to their utmost. However, when the stopwatch meets the marketing department, it appears that Oracle did it's best by leaving some existing oracle functionality on the table, and going so far as pay for some outside replacement functionality.

    Therefore, the percentage you seek, 78.2% or 74.5% (or 30%) etc, depends on the specific application, but we know that 'complete' is undesirable. It means 100%, and only the DBMS or middleware bigot say you should shower with only the hot or cold.
