Workflow Diagrams

The vector stencils library "UML class diagrams" contains 38 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"... classes are represented with boxes which contain three parts:
(1) The top part contains the name of the class. It is printed in Bold, centered and the first letter capitalized.
(2) The middle part contains the attributes of the class. They are left aligned and the first letter is lower case.
(3) The bottom part gives the methods or operations the class can take or undertake. They are also left aligned and the first letter is lower case. ...
To indicate a classifier scope for a member, its name must be underlined. ...
An association can be named, and the ends of an association can be adorned with role names, ownership indicators, multiplicity, visibility, and other properties. ...
Aggregation ... is graphically represented as a hollow diamond shape on the containing class end of the tree with a single line that connects the contained class to the containing class.
... graphical representation of a composition relationship is a filled diamond shape on the containing class end of the tree of lines that connect contained class(es) to the containing class.
... graphical representation of a Generalization is a hollow triangle shape on the superclass end of the line (or tree of lines) that connects it to one or more subtypes.
... graphical representation of a Realization is a hollow triangle shape on the interface end of the dashed line (or tree of lines) that connects it to one or more implementers. A plain arrow head is used on the interface end of the dashed line that connects it to its users.
Multiplicity ... representation of an association is a line with an optional arrowhead indicating the role of the object(s) in the relationship, and an optional notation at each end indicating the multiplicity of instances of that entity (the number of objects that participate in the association).
Entity classes ... are drawn as circles with a short line attached to the bottom of the circle. Alternatively, they can be drawn as normal classes with the «entity» stereotype notation above the class name." [Class diagram. Wikipedia]
The example "Design elements - UML class diagrams" is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.

"A security alarm is a system designed to detect intrusion – unauthorized entry – into a building or area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders. Car alarms likewise protect vehicles and their contents. Prisons also use security systems for control of inmates.

Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multi-area systems with computer monitoring and control." [Security alarm. Wikipedia]
The example "Security system plan" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Security and Access Plans solution from the Building Plans area of ConceptDraw Solution Park.
