Currently, there are two business value metric tables. These tables provide key performance metrics or ratios:
The D_BUSINESS_VALUE_DETAILS (BVD) table provides a full list of key statistics and calculated performance ratios used in detailed MUF analysis. This set of metrics was created from known common DBA practices that have been developed of the years to measure CA Datacom performance.
The D_BUSINESS_VALUE_METRICS (BVM) table provides a short collection of high-level statistics and calculated performance ratios as related to the Business Value Metrics spreadsheet for system measurement and performance. These business value metrics provide a simple way for you to measure the overall performance (or business value) of a given MUF. Business value metrics have been introduced in recent years as a common way for you to measure and compare performance of your MUFs.
These ratio tables are built by collecting information from all detail rows for a given Delta rowset and summarizing them into a single row. For each Delta rowset, one row is added to the BVM and BVD tables.
The purpose of this summarization is to provide precalculated measurement statistics for each of the Delta periods that could be used to reduce the amount of day-to-day review that is performed on a given set of Delta statistics. You can use these summarization and measurement statistics to provide the primary performance reporting for a given MUF. Only when a problem or concern is detected would additional drill-down into the detail Delta tables be needed.
Unlike the detail Delta tables, the BVM and BVD tables are not modeled after any specific DST table. However, we strived to maintain a consistency between the column name and use in the BVM and BVD tables with that in the Delta and DST tables. In most cases, the column in the BVM and BVD tables represents the total for that column from all rows in a selected Delta rowset.
