SQL Server 2000 vs Oracle.
I started off my career supporting MS all the way......basically am still in the same team. But apparently, and again....most of the big service companies(eg.insurance, healthcare,etc) turn in a sad face when they are told that their data will be hosted on SQL Server 2000. For some reason, they still think that only DB2 or Oracle are qualified enough to even think of hosting so much data. Honestly, I am not biased, I don't know too much of Oracle....and know nothing in DB2....but know a decent length in SQL server 2k.
And just when I started to read up on SQL server 2005, and try to convince my boss to implement it as soon as it releases, the management decides that all data from now on will be hosted on Oracle (hosted in a linux environment). damn...i hate linux soo much from a developer's perspective.
Ah well...stole a PL/SQL book from my collegue, got to start reading up on it now.
