[dba-Tech] Overview of Sharepoint Server

I have a customer I've been trying to get a project started with for about 9
months now (large company).  Two weeks ago we had what was supposed to be
the last 'approval' meeting with a group of people from various IT
functions.  Yesterday my customer told me that a higher-level IT manager has
suggested that he look at Sharepoint Server as a possible alternative before
he makes a decision on what technology to use.  

 

So - can someone point me to where I can read a good overview of what
Sharepoint does?  What are it's pros/cons, etc.  Beyond MS marketing -  how
have people really used it to their advantage and what should it not be used
for?

 

Thanks!
