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.

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.
The vector stencils library "UML activity diagrams" contains 37 symbols for the 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:
(1) rounded rectangles represent actions;
(2) diamonds represent decisions;
(3) bars represent the start (split) or end (join) of concurrent activities;
(4) a black circle represents the start (initial state) of the workflow;
(5) 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.
Hence they can be regarded as a form of flowchart. Typical flowchart techniques lack constructs for expressing concurrency. However, the join and split symbols in activity diagrams only resolve this for simple cases; the meaning of the model is not clear when they are arbitrarily combined with decisions or loops."

This purchase order processing UML activity diagram was created on the base of activity diagram from the software architecture documentation wiki of the Software Engineering Institute (SEI) of Carnegie Mellon University (CMU).
[wiki.sei.cmu.edu/ sad/ index.php/ Image:PurchaseOrderActivityDiagram.png]
"A purchase order (PO) is a commercial document and first official offer issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services. Acceptance of a purchase order by a seller forms a contract between the buyer and seller, so no contract exists until the purchase order is accepted. It is used to control the purchasing of products and services from external suppliers.
Creating a purchase order is typically the first step of the purchase to pay process in an ERP system." [Purchase order. Wikipedia]

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.

UML Sample Project

Unified Modeling Language (UML) is a graphical modeling language for describing, visualizing, projecting and documenting of object oriented systems. UML digram is used for modeling of organizations and their business processes, for development the big projects, the complex software applications. Comprehensive UML diagram allows to create the set of interrelated documents that gives the complete visual representation of the modeling system.
This example of automated payroll management system UML activity diagram was created on the base of figure on the webpage "Automated payroll management system" from ethelmandane.wikispaces.com.
"In the Philippines and in other foreign countries the government has a trend to embrace automation for process efficiency. One of the processes that are being automated is the payroll process. Payroll is the total amount required to pay workers and employees during a week, month or other period.
One of the government offices that desires to automate their payroll system is the NSO Camarines Sur which is located 2nd Floor MMCN Building, Panganiban Avenue, Naga City. The National Statistics Office (NSO) envisions to be recognized as a world-class provider of statistical and civil registration products and services and lives with its mission to produces and provides quality statistical and civil registration products and services. ...
The project seeks to create an Information System Plan for an Automated Payroll Management System. ...
The creation of the Information System Plan will benefit the accounting section of the organization. Specifically it is significant to:
1. Administrative Assistants. It will help to lessen time and effort in preparing and computing the salary of the employee.
2. NSO. It will help the organization to be more productive and efficient."

However, the join and split symbols in activity diagrams only resolve this for simple cases; the meaning of the model is not clear when they are arbitrarily combined with decisions or loops.
While in UML 1.x, activity diagrams were a specialized form of state diagrams, in UML 2.x, the activity diagrams were reformalized to be based on Petri net-like semantics, increasing the scope of situations that can be modeled using activity diagrams. These changes cause many UML 1.x activity diagrams to be interpreted differently in UML 2.x." [Activity diagram. Wikipedia]

"A swim lane (or swimlane) is a visual element used in process flow diagrams, or flowcharts, that visually distinguishes responsibilities for sub-processes of a business process. Swim lanes may be arranged either horizontally or vertically. In the accompanying example, the swimlanes are named Customer, Sales, Contracts, Legal, and Fulfillment, and are arranged vertically. ...
When used to diagram a business process that involves more than one department, swimlanes often serve to clarify not only the steps and who is responsible for each one, but also how delays, mistakes or cheating are most likely to occur.
Many process modeling methodologies utilize the concept of swimlanes, as a mechanism to organize activities into separate visual categories in order to illustrate different functional capabilities or responsibilities (organisational roles). Swimlanes are used in Business Process Modeling Notation (BPMN) and Unified Modeling Language activity diagram modeling methodologies." [Swim lane. Wikipedia]

UML Diagram

The accepted open standard that is used in software engineering and system design, when modeling object-oriented systems and business processes is known as Unified Modeling Language (UML). UML was created for definition, visualization, design and documentation software systems. It isn't a programming language, but on the base of UML model can be generated code. UML uses generic set of graphic notations for creation an abstract model of the system called UML-model. The UML notation lets visually represent requirements, subsystems, structural and behavioral patterns, logical and physical elements, etc. UML defines 13 types of diagrams: Class (Package), Use Case, Sequence, Object, Collaboration, Component, Timing, Interaction Overview, State Machine, Composite Structure, Activity, and Deployment. All these types of UML Diagrams can be fast and easy created with powerful ConceptDraw DIAGRAM software extended with special Rapid UML solution from Software Development area of ConceptDraw Solution Park.
