The Challenge

  • As a result of an impressive growth strategy, Piedmont’s incumbent MS SQL Server system could no longer scale in line with the healthcare provider’s demands
  • The cost of data analytics continued to increase due to mounting security and performance issues with the incumbent solution
  • The healthcare provider wanted to overhaul and revolutionize its ability to process, understand and gain insights from data

The Solution

  • Piedmont opted for Exasol so it can meet the ever-growing analytic demands of the business; the database complements the front-end visualization tool Tableau.
  • Complex analytic queries on vast amounts of data are now answered in seconds, the provider can analyze more data than ever before and front-end users now gain much deeper insights into important data.
  • Exasol has replaced the incumbent data warehouse system – both Piedmont’s core repository as well as systems in place for its subsidiary companies PiedmontClinic and Piedmont Physicians Group.
