Unanswered: Market share of the RDBMS players
Can anyone help with information for teh queries given below:
Market share of all the big time RDBMS players like Microsoft, Oracle, IBM, Sybase and the others
Oracle is around 65%, DB2 -24%, The rest is shared by the rest
It does depend greatly on the platform also.
High End OS/390,MVS,OS/400 = DB2, IMS, IDMS, VSAM, Oracle (in no particular order, but the IBM products basically own that market.)
Unix = Oracle's share is huge, but DB2/UDB is making major inroads into that marketplace. Sybase is still around, Informix is being assimilated by IBM.
NT/2K = Primarily SQL/Server and Oracle
Each vendor will tell it's own story. Figure out what you want and find the RDBMS that suits that direction.
