Diagramming Software for Design UML Activity Diagrams

Activity diagram describes the business and operational step-by-step workflows of components in a system. An activity diagram shows the overall flow of control.
This example was drawn on the base of SysML activity diagram on the page 8 of "SysML Modelling Language explained" document from the Official OMG SysML site.
"The activity diagram represents steps of a process, often making use of “input and output pins” that respectively correspond to the element type required as the input of an activity or action, and the element generated as an output.
If an action or activity corresponds to a block operation, it is possible to ensure that the types of the input and output of this activity are consistent with the block operation signature.
All the activity diagrams definitions used in UML also apply to SysML.
SysML has added a couple of extensions:
- With UML, control can only enable actions to start. SysML extends control to support disabling of actions that are already executing.
- Definition of the flow rate : continuous or discrete
- Definition of the rate and probability on the control or object flows"
[omgsysml.org/ SysML_ Modelling_ Language_ explained-finance.pdf]
The example "SysML activity diagram" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the SysML solution from the Software Development area of ConceptDraw Solution Park.

UML Activity Diagram. Design Elements

UML Activity Diagram illustrate the business and operational step-by-step workflow of components in a system and shows the overall flow of control.

UML Activity Diagram

UML Activity Diagram is a type of UML diagrams, which illustrates the business and operational step-by-step workflows of components within a system and shows the overall flow of control. UML Activity Diagram is constructed from a limited number of shapes, connected each other with arrows. The most important shape types are rounded rectangles, diamonds, bars, black circle, encircled black circle. The arrows represent the order in which activities happen and run from the start towards the end. ConceptDraw DIAGRAM software enhanced with Rapid UML solution is ideal for software designers and software developers who need to draw the UML Activity Diagrams and other types of UML diagrams. It is convenient to use the appropriate stencils of UML notation from the UML Activity library included to the Rapid UML solution of ConceptDraw Solution Park and containing a lot of specific vector UML objects. Use them to design your own UML Activity Diagrams, make them colorful and attractive with style tools of ConceptDraw DIAGRAM software.
This vector stencils library contains 47 SysML activity diagram symbols.
Use it to design your SysML activity diagrams using ConceptDraw PRO diagramming and vector drawing software.
"Activity diagrams are constructed from a limited number of shapes, connected with arrows. The most important shape types:
- rounded rectangles represent actions;
- diamonds represent decisions;
- bars represent the start (split) or end (join) of concurrent activities;
- a black circle represents the start (initial state) of the workflow;
- an encircled black circle represents the end (final state).
Arrows run from the start towards the end and represent the order in which activities happen." [Activity diagram. Wikipedia]

Data Flow Diagram

Data Flow Diagram (DFD) is the part of the Structured Systems Analysis and Design Methodology (SSADM), which is intended for information systems projection and analysis. Data Flow Diagrams allow graphically represent the data flows in information system and analyze the data processing during the structural projection. This type of diagrams lets visually show a work of information system and results of this work, it is often used in connection with human processes and can be displayed as Workflow diagram. Data Flow Diagram visualizes processes and functions, external entities, data depositories, and data flows connecting these elements and indicating direction and data character. Each of these elements used for DFD has its own graphical notation. There are two notations to draw DFDs - Yourdon & Coad and Gane & Sarson. ConceptDraw DIAGRAM extended with Data Flow Diagrams (DFD) solution from Software Developmant area is ideal for designing professional looking DFDs, which can be then easily exported in various formats.

UML Diagram Types List

Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.

Data Modeling Diagram

The vector stencils library Activity diagrams from the solution Rapid UML contains specific data modeling symbols for ConceptDraw DIAGRAM diagramming and vector drawing software. The Rapid UML solution is contained in the Software Development area of ConceptDraw Solution Park.
"An activity in Unified Modeling Language (UML) is a major task that must take place in order to fulfill an operation contract. Activities can be represented in activity diagrams.
An activity can represent:
(1) The invocation of an operation.
(2) A step in a business process.
(3) An entire business process.
Activities can be decomposed into subactivities, until at the bottom we find atomic actions.
The underlying conception of an activity has changed between UML 1.5 and UML 2.0. In UML 2.0 an activity is no longer based on the state-chart rather it is based on a Petri net like coordination mechanism. There the activity represents user-defined behavior coordinating actions. Actions in turn are pre-defined (UML offers a series of actions for this)." [Activity (UML). Wikipedia]

IDEF0 Flowchart Symbols

The modeling of business and business processes is not quite a simple process for both small-size businesses and large businesses. The IDEF0 method is one of the popular and easy methods of modeling the business as a complex system. It is based on the functional modeling language Structured Analysis and Design Technique (abbr. SADT) and is concentrated on the activity modeling. According to this method are constructed the IDEF0 Diagrams and IDEF0 Flowcharts, which are succesfully used not only for documenting the business, but also for analysis, development, integration of information and software systems, reengineering, etc. This method suggests the use of special IDEF0 Flowchart Symbols from the IDEF0 notation for construction the IDEF0 Flowcharts. ConceptDraw DIAGRAM diagramming and vector graphic software extended with IDEF0 Diagrams solution from the Software Development area of ConceptDraw Solution Park is rich for the powerful drawing tools, built-in templates and samples, and predesigned IDEF0 flowchart symbols.
