Product is mission critical, and thus ongoing formal and comprehensive safetyĪnalysis is a major obligation and effort. You mean you are letting me know that, nevertheless, it is system engineeringĬustom to show things as if the data is copied and passed directly fromĪction to action (and I can do without the datastore)? (Assertion (A)) Physically copy the output structure of action n to the input parameter of Structure from to action to action (action n to action n+1). Particular activity, the activity specifically does not copy the ![]() Reverse-engineering effort to document how my company’s system is structuredĪnd how it really works, at least at the top levels. Rather, my diagram is part of a large-scale > Block … and pass it from action n to actionĬlarify: my activity diagram is not for a general sketch or requirementsĪnalysis. Since it seems I was not clear enough, I changed my exampleĭiagram slightly – below at end of post. It is not key that the data structure is a list, or some other structure.Įach process step of the activity updates the same structure, which I showed asĪ side data store, and I was asking whether the > element > Each action can read the list, perform its calculation andĪppend a new value to the end of the listītw, the activity’s function is not to add values to the Thank you, James and Wolfgang, for your responses. The data storage exists only during the activity.ġ: Is the UML datastore element the correct element to use forĢ: Assuming datastore is the appropriate element, have I ![]() On completion of all processing, the activity copies theĭata storage content to the output parameter. Need some sort of data storage to act as a sort of “accumulator” of the latest values Then Step 2 starts processing the data set updated by Step 2, and so on.

Same data structures (which were originally input into the activity). The diagram describes a sequence of algorithms, each algorithm working on the Mean, using «datastore» as I currently understand it. In the activity diagram below, I tried to describe what I Then, then what? And if yes, then I want to verify I am using it correctly. I want to verify that the «datastore» element is what I need.
