Response: Health Catalyst’s solution is not OLAP based. The base of our solution is the EDW—a data warehouse. OLAP and data warehouses complement each other. A data warehouse stores and manages data, whereas OLAPs convert data into a strategic format. Many of our analytical applications and offerings, such as KPA, Cohort Finder, and Population Explorer, leverage tools such as QlikView, which provides this OLAP-like slice-and-dice capability.

The speed and efficiency of calculations are still maintained through the power of the database on which the EDW resides and the in-memory features and functionality of visualization tools such as QlikView, which allows the end user to quickly and efficiently analyze data
