Study Notes
Event Decomposition Technique
- When defining system requirements, start by asking which business events require the system's response.
- This approach helps analysts maintain a high-level view of system scope, focusing on what events the system needs to react to, rather than its internal workings.
Tracing aTransaction' s Life Cycle
- A useful technique for identifying events is to trace the sequence of events that might occur for a specific external user or transaction.
- These events can include system design choices, system controls, and occurrences important to the system but not directly affecting users or transactions.
Events and Use Cases
- Events can be deferred until system design if they are not directly related to user interactions or system controls.
- For each temporal event, identify and name the associated use case, and then establish its trigger point.
- Consider the state events that your system might encounter.
- Ensure that any identified events are truly necessary and not based solely on the assumption of perfect technology, unlimited storage, and completely honest system users.
