Cambridge, MA—January 28, 2002—InterSystems Corporation today announced the results of a survey comparing InterSystems and Oracle database technology conducted by the KLAS Enterprises research and consulting firm. Based on a survey of 110 healthcare IT executives, InterSystems’ software rated higher than Oracle on every measure.

“We were pleased to participate in a survey that assesses database performance measurement in a quantifiable, controlled way,” says Paul Grabscheid, InterSystems vice president of strategic planning. “The information KLAS collected and analyzed validates what our application partners and end users already know—that InterSystems’ CACHÉ database software successfully fulfills the most demanding requirements of the healthcare technology market.”

Anatomy of Database Success

The KLAS study compared the performance of leading healthcare applications using InterSystems or Oracle database systems. Areas of measurement included response time, database reliability and speed, hardware and support personnel requirements and downtime. Extensive interviews were conducted with healthcare IT managers and executives who have an in-depth knowledge of the applications and technical issues. Additional data was gathered through a KLAS evaluation process that gathers input from healthcare CIOs and directors on more than 300 healthcare IT products.

InterSystems’ database products rated better than Oracle’s in every satisfaction measurement, with the biggest CACHÉ advantage being in the area of reliability, according to the KLAS report. Further, InterSystems’ database products outperformed Oracle’s by more than 2:1 in hardware required and 2.5:1 in the number of database administrators (DBAs) required.

Among survey findings:

  • Users rated CACHÉ significantly higher in the areas of database software reliability and scalability with InterSystems software enjoying a 0.6 – 0.9 gap over Oracle (where a 0.5 difference is considered significant).
  • The reliability gap was the biggest difference measured in the study. When asked about downtime, 60% of CACHÉ users reported that they had no unscheduled downtime—more than triple the rate (18%) of Oracle users.
  • Respondents reported significantly higher scores for CACHÉ in terms of speed and scalability with InterSystems’ database software rated 0.7 over Oracle (where a 0.5 difference is considered significant).
  • Although CACHÉ delivered better performance with a significantly more demanding workload, cost of operations was more economical with InterSystems database products users reporting a 2.1:1 advantage in hardware required and a 2.5:1 advantage in DBAs required.

Database for Top-Rated Healthcare Applications

KLAS summarized the results by stating “the true measure of a solution is its performance in live operation. The data is in and the measurement has been taken. When we cut through all the hype about technology, state-of-the-art solutions, object oriented systems, relational databases and client/server, we can see that InterSystems databases continues to serve the healthcare community as a core component in the best rated systems in the market.”

KLAS is the only U.S. research and consulting firm specializing in monitoring and reporting the performance of healthcare IT vendors. The research firm’s annual 2001 Top 20 Report validates the prominent, successful use of InterSystems software among healthcare application providers.
