Flowchart
Introduction
The flowchart or flowchart or activity diagram is the graphical representation of an algorithm or process. It is used in disciplines such as programming, economics, industrial processes and cognitive psychology.
In Unified Modeling Language (UML), it is an activity diagram that represents step-by-step workflows.
These diagrams use symbols with defined meanings that represent the steps of the algorithm, and represent the flow of execution through arrows that connect the start and end points of the process.
Work standards
The following are actions prior to creating the flowchart:
The steps to follow to build the flow chart are:.
Description
In UML 1.x, an activity diagram is a variation of the UNL state diagram where "states" represent operations, and transitions represent the activities that occur when the operation is completed.
The UML 2.0 message diagram, while similar in appearance to the UML 1.x activity diagram, now has Petri net-based semantics.
In UML 2.0, the general interaction diagram is based on the activity diagram.
The activity diagram is a special form of state diagram used to model a sequence of actions and conditions taken within a process.
The Unified Notification Language (UNL) specification defines an activity diagram as:.
The purpose of the activity diagram is to model a workflow process and/or to model operations.
An operation is a service provided by an object, which is available through an interface.
An interface is a group of operations related to semantics.
