Submit Comments to Pluck
An example of interaction overview diagram which shows how user comments on some article are submitted to Pluck using various AJAX technologies. (See example of sequence diagram with similar semantics at Submit Comments to Pluck using DWR, AJAX, JSON.)
Comments that look Ok are submitted to Pluck server hosting all comments to all articles. AJAX technology is also used in this case both to submit the new comment as well as to get back the list of all recent comments (including the new one). JSON is used to get comments back.
This diagram also shows some duration constraints. (Disclaimer: constraints shown are fictitious and not describing any real communication.) For example, according to the diagram callback waiting time for posted comment varies from 1 to 4 seconds. At the same time, requesting all posted comments takes only up to 100 msec.
