“Lycia allows an unexpectedly high ROI by preserving your invaluable applications that have been working for years, while turning them into modern applications”

Eric Vercelletto Member of the Board of Directors of IIUG, President at Guide-SHARE France, groupe Informix

“It has always seemed that when you purchase Lycia or any of their other products you aren’t buying software but are being granting membership in the Querix family”

Art S. Kagel President and Principal Consultant at ASK Database Management
