Technology
The requirement
for speed, volume and accuracy made it impractical to deploy anything
but a sophisticated CATI (Computer Aided Telephone Interviewing) system.
Unfortunately, no off-the-shelf system could handle the combination
of massive amounts of real-time data flows and extreme complexities
inherent in a labor market survey. Consequently, we built our own from
the ground up.
ERISS has
spent tens of thousands of man-hours and millions in R&D to perfect
a system that today is recognized as one of the most flexible and efficient
business intelligence collection systems in existence.
The CATI system
alone encompasses dozens of internally developed software systems to handle everything
from survey preprocessing, call processing, targeting and management,
to post-processing data validation, integration and aggregation.
Dozens of additional applications support
the many web-based, interactive dissemination tools developed and hosted by ERISS. These, in turn, interact with our
sophisticated phone, email and fax messenger services that handle large volumes of communication between employers, jobseekers
and workforce professionals. In addition, an entire suite of programs and servers are dedicated to
scraping, classifying and aggregating tens of thousands of new job openings every day in support of
our real-time salary and job market scans.
These systems access a constantly growing data store
approaching 1/2 Terra bytes of internal information (500 Giga bytes).
All systems are hosted in our
state-of-the-art data center containing 24 servers connected to the outside world with eight T-1 lines. All ERISS web applications and dissemination tools are hosted
and maintained internally.
The result is a new breed of information
that is more current, more local and more detailed than ever possible before.
