Logical query processing phase of INSERT, DELETE, and UPDATE in SQL queries

I am curious about the logical query processing phase of SQL queries.

For SELECT queries, the logical query processing phase order is:

FROM
ON
OUTER
WHERE
GROUP BY
CUBE | ROLLUP
HAVING
SELECT
DISTINCT
ORDER BY
TOP

What is the order for INSERT, for UPDATE and for DELETE?

If you would like to know what the actual query processing order is, take a look at the execution plan. That will tell you step by step exactly what SQL Server is doing.
