UML 2 Diagrams Sequence Diagram The Sequence Diagram models the collaboration of objects based on a time sequence. It shows how the objects interact with others in a particular scenario of a use case. With the advanced visual modeling capability, you can create complex sequence diagram in few clicks. Besides, VP-UML can generate sequence diagram from the flow of events which you have defined in the use case description.

Sequence Diagram Sample The Sequence Diagram models the collaboration of objects based on a time sequence.

Frame An interaction is a unit of behavior that focuses on the observable exchange of information between ConnectableElements.(OMG Unified Modeling Lanauge Specification - UML 2.0 Superstructure Specification, p. 525)

Lifeline A lifeline represents an individual participant in the Interaction. While Parts and StructuralFeatures may have multiplicity greater than 1, Lifelines represent only one interacting entity.(OMG Unified Modeling Lanauge Specification - UML 2.0 Superstructure Specification, p. 536)

ExecutionSpecification An ExecutionSpecification is a specification of the execution of a unit of behavior or action within the Lifeline. The duration of an ExecutionSpecification is represented by two ExecutionOccurrenceSpecifications, the start ExecutionOccurrenceSpecification and the finish ExecutionOccurrenceSpecification.(OMG Unified Modeling Lanauge Specification - UML 2.0 Superstructure Specification, p. 521)

InteractionUse An InteractionUse refers to an Interaction. The InteractionUse is a shorthand for copying the contents of the referred Interaction where the InteractionUse is. To be accurate the copying must take into account substituting parameters with arguments and connect the formal gates with the actual ones.(OMG Unified Modeling Lanauge Specification - UML 2.0 Superstructure Specification, p. 532)

CombinedFragment A combined fragment defines an expression of interaction fragments. A combined fragment is defined by an interaction operator and corresponding interaction operands. Through the use of CombinedFragments the user will be able to describe a number of traces in a compact and concise manner.(OMG Unified Modeling Lanauge Specification - UML 2.0 Superstructure Specification, p. 507)

StateInvariant / Continuations A Continuation is a syntactic way to define continuations of different branches of an Alternative CombinedFragment. Continuations is intuitively similar to labels representing intermediate points in a flow of control.A StateInvariant is a runtime constraint on the participants of the interaction. It may be used to specify a

variety of different kinds of constraints, such as values of attributes or variables, internal or external states, and so on.(OMG Unified Modeling Lanauge Specification - UML 2.0 Superstructure Specification, p. 516)
