Events of Things with Associated Actions
- There exist a super-set of things, in which each element is in a certain state, as well as respective associated actions on, or performed by, those things.
- Each state of a thing is a separate element--That is, things with multiple states are actually multiple elements of individual things, each in their own singular, certain state.
- An action can be the change of state, or the cause of a change of state.
- A thing has a separate state for each associated action it performs.
- Multiple things can be associated with a single action as well as multiple actions with a single thing--things and actions have n-way associations, where n is a positive integer.
- Each state of a thing is a separate element--That is, things with multiple states are actually multiple elements of individual things, each in their own singular, certain state.
- A sequence formed of a single thing with an associated action is called an event.
- A sequence formed of multiple events using the shared associations of things or actions in each preceding or following event is called a sequence of events.
- A sequence formed of multiple events using the shared associations of things or actions in each preceding or following event is called a sequence of events.
- The set of events that occur due to being caused by another event action are called secondary events.
- Secondary events can also be called autonomous events with their respective things called autonomous actors.
- A contrary set of events that do not occur as the result of other events actions, are primary events.
- The respective things in these primary events are called primary actors.
- The respective things in these primary events are called primary actors.
- Primary actors are the start of every sequence of events.
- With this model people are typically the primary actors.
- With this model people are typically the primary actors.
The computer information systems we are dealing with can be broken down into things, actions, events, sequences and actors.
Types of Actors
We have built up to addressing actors via the notion of things in state and associated actions. However,
