hi everybody!

i would like to congratulate exforsys for starting this new learning series on datawarehousing.. i have gone through the first two tutorials.. the language is quite easy and simple.. i have some queries about it:

1. r u also going to give tutorials on how to use specific tools like informatica, datastage, etc.?
2. in total how many tutorials u r going to give about datawarehousing and within how much time u will cover all these tutorials?
3. wat is the full form of OLTP? wat is the difference between OLAP and OLTP?
4. when conventional datawarehousing is able to handle and answer complex queries than wat is the need of OLTP and OLAP?

thanks
