DB2's Market Share
I am doing some research for a presentation next week. I'll be talking about Oracle and DB2's market share. I remember reading somewhere that Oracle's maket share is 44% and DB2's is just above 21%.
DB2 enjoys complete monopoly in Mainframe domain because the only database that works with Mainframe is DB2. Right?
My question is:
Out of that 21% market share that DB2 has, what percentage does sales for Mainframe's DBs constitute?
