SAP BWA

High data volumes

Queries often require access to many millions, and in some cases billions

of records.

Challenging response time SLAs

Your community want predictable and stable response times for their

queries.

Unpredictable types of queries

Traditional optimization and caching strategies rarely handle drill down

and ad-hoc queries particularly well.

Aggregates

The use of aggregate helps with known common and known queries but

require custom design and takes up time and ongong consulting costs.

With BWA

The two queries above both show that BWA provides this customer with large increases in performance on standard queries compared to aggregates. The best case of these two situations BWA provides a response 15 times faster than the same query with aggregates.
