I need a proper guidance and information.I am a 4+ year experienced IT professional.
2.5 years i have worked on Mainframe technologies as COBOL,JCL,VSAM and DB2.I was working on the OLTP transactions environment. For last 1.5 years i am working on teradata on mainframes. Its a datawarehousing project.I find the datawarehousing concepts very different from my previous work concepts. Somehow i am not very comfortable working in this new project.
Moreover,i am in a dual mind that being from a Mainframe background, i need to work on Db2 more that any other RDBMS.In mainframes Db2 is the most widely used DB. So, i feel i am wasting my time working in teradata and datawarehousing.I feel i will have a tough time in future working in MAinframes after working in this project for so long.
people having more experience than me can guide me well, i believe.
