The integration of advanced analytics into a transactional database is revolutionary.

Today a majority of advanced analytic applications use a primitive approach of moving data from databases into the application tier to derive intelligence.

The downside is that the threshold is very high for tables with a large number of rows which leads to updates occurring less frequently which can cause performance issues.

In order to trigger the auto update statistics feature in SQL Server, the number of updated rows should exceed 20% of the table rows.

This approach incurs high latency because of data movement, doesn’t scale as data volumes grow and burdens the application tier with the task of managing and maintaining analytical models.
