[postgis-users] manipulate vs analysis

[Robert W. Burgholzer]

Following is my take on your question, although I don;t know the strict 
definition:
In postgresql/postgis, as in any SQL implementation, everything can be viewed 
as analysis, unless ones explicitly uses an update statement.

Thus, SELECT is analysis, UPDATE is manipulation.

But, this is just me,
