Good comparison, but Teradata is still missing ;-)
You could add some info:
Starting with SQL Server 2005 Microsoft supports a limited subset of
SQL:2003 OLAP functions, too.
Ranking functions:
RANK, DENSE_RANK, ROW_NUMBER
OLAP aggregates, but a window definition is not supported, it defaults to:
ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING
e.g. SUM(x) OVER (PARTITION BY y)
