A Case Study: How to Extend Your Vendor Data Warehouse

A Case Study: How to Extend Your Vendor Data Warehouse

Norman Daoust, Daoust Associates and Paul Labonte, Southcoast Health

The typical choices organizations consider for a data warehouse are buy or build. However, for those organizations where those two choices are too limiting, an alternative is to purchase a vendor data warehouse and extend it. The presentation will describe how one healthcare provider network chose to purchase their primary vendor’s data warehouse and extend it to meet their needs. We will highlight the challenges a healthcare provider network organization faced in extending the data warehouse of their well-known vendor, how we overcame them, and important considerations for your organization if it is considering this option.

What will attendee learn?

Attendees will learn pitfalls to avoid, challenges to overcome, questions to ask your vendor, and tips to employ.
