Pulling OS and Database Std/Ent in VM

Hi All,

I'm newbie to powercli.I'm started learning things which I can automate in my environment.I need to pull the OS, Version(2008,2012), edition(std,ent) ,Type of Database(MS,Mysql), DB version and DB edition(std,ent).

I'm seen script from Alan's blog(http://www.virtu-al.net/2009/10/12/powercli-more-hal-information/) which solve my first part of my question, but how about the database.

and one question while exporting the script to csv,i often see usage of "-NoTypeInformation",May I know why we are using it?

Thanks in Advance.
