About

  • purpose: root events table -- all task-specific events tables refer to this one

fields

  • ID_Client: ID of client that generated the event
  • When: When the event occurred.
    • If an event-type has a beginning and end, the auxiliary table for that type may treat When as "when started" and add a WhenComplete field to indicate when the event was complete.
  • Type: short string indicating which type of event, i.e. which class to use (and which auxiliary event table to look at).
  • What: automatically-generated human-friendly description of what happened
