Very out of date...

some example :
Statistics Gathering:
CPU Costing, says no... But it is YES
Disk / IO Costing, says no... But it is YES
Since a lot !

Query Management:
Query/Resource Governor, says no... But it is YES (since V 2008)
View historic queries in system cache, says no... But it is YES
(since V 2005)

Parallelism
Parallel Sorts, says ?... But it is YES (since a lot)
Parallel Index (re)build, says ?... But it is YES (since V 2005)
Parallel (table) Reorganisation, says ?... But it is YES (since a lot)

same on datatype
DATE, TIME, DATETIME WITh TIME ZONE... have been added to 2008 version**

and some indication are wrong.
Example :
CLOB Datatype sauys no. It is yes vith text type almost since v 7 (1999 !)

Totally incomplete for date functions...
