Although I-flex’s (read oracle) Flexcube still leads the race, it may be losing out to infosys and SAP due to fear of oracle centric platforms in future.
Maverick 
flexcube will not exist if ORcale Database & Orcale Applications were not there. What is being done currentoly is just enhancing the flexcube product to accomodate new version of oracle products.
they also have another product called reveleus (www.reveleus.com) which works on DB2 & SQL. But it is not used like Flexcube…
good one
