Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
An activity diagram, with the activity "Cooking Spaghetti" outlined with an "Activity frame" An activity in Unified Modeling Language (UML) is a major task that must take place in order to fulfill an operation contract. The Student Guide to Object-Oriented Development defines an activity as a "sequence of activities that make up a process."
This view includes sequence diagrams, activity diagrams and state machine diagrams. UML models can be exchanged among UML tools by using the XML Metadata Interchange (XMI) format. In UML, one of the key tools for behavior modeling is the use-case model, caused by OOSE. Use cases are a way of specifying required usages of a system.
The ACD is a modeling tool that was developed in 1960 following the flow diagram method of K.D. Tocher. [2] It pertains to the activity-based paradigm of system modeling, as opposed to process-oriented or event-based paradigms.
Signal - an Event which can occur in an Activity diagram in three different ways: as a Time Signal, as a signal which an Activity can listen for and a signal which an Activity can send; State - an Object exists at one of the States described in a State machine diagram. A state encompasses all the properties of the object along with the values ...
The refined representation of a process can be done in another data-flow diagram, which subdivides this process into sub-processes. The data-flow diagram is a tool that is part of structured analysis and data modeling. When using UML, the activity diagram typically takes over the role of the data-flow diagram. A special form of data-flow plan ...
A project network diagram is a graph that displays the order in which a project’s activities are to be completed. Derived from the work breakdown structure , the terminal elements of a project are organized sequentially based on the relationship among them.
