What are operations in eZ Publish context?

I've seen them lying around (among other places, in relation to the shop module), and while playing around with the ggsysinfo extension, I noticed it had a separate view listing all the installation operations. However, as I've never had the need for them yet, I'm uncertain as to their purpose. Sincerely, Eirik Alfstad Johansen http://www.netmaking.no/

Imho any change to content should be coded within an "operation", and views should be little but wrappers around them. The advantage is that it would make it much easier to interact with the system using php code, webservices or anything else that bypasses views.
