Hi, I am new to this community and don't now whether its ok to ask this question here, but I would really appreciate if someone can help.
I am working in an IT Company in a support role and have been waiting for a due promotion from last few years, now the management says I will have to develop some IT skills to get a promotion.
Since I am working in project management role for an Oracle team, I was advised by my manager to learn something in oracle.
After much research I have considered SAP/Oracle and SAS since these 3 are in demand in my company as well as outside, I am also considering moving out of my current organization. I have certain limitations, I can not afford to do the training by an institute and right now I want to look for online free material, I know little bit of SQL. Can anyone please suggest which skill would be best to learn online free.
