Development History
• Pre$1999 – Universal Translator started to deal
with trend logger data (MS Access)
• 2006 – UT2 started for handling larger data sets
(SQL as internal database)
• 2010 – UT3 started to provide open platform with
API (Advanced Programming Interface)
for 3rd party developers, and custom
database for higher speed

Development History
• UT3 is a PIER$funded collaboration
between
– Lawrence Berkeley Laboratory
– Quest
– NIST
– PG&E (Merging Solutions is
programming team)
