The differences between timing diagram and sequence diagram are the axes are reversed so that the time is increased from left to right and the lifelines are shown in separate compartments arranged vertically. A timing diagram is a special form of a sequence diagram. Timing diagrams are used to explore the behaviors of objects throughout a given period of time. 'A timing diagram in the Unified Modeling Language 2.0 is a specific type of interaction diagram, where the focus is on timing constraints. Use it for object-oriented modeling of your bank information system. The vector stencils library 'Bank UML timing diagram' contains 8 shapes for drawing UML timing diagrams.

The example 'Design elements - UML timing diagrams' is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park. Typically this graphical association is a small line, e.g., between an occurrence specification and a time interval.' Time constraint is shown as graphical association between a time interval and the construct that it constrains. All traces where the constraints are violated are negative traces, i.e., if they occur, the system is considered as failed. The semantics of a time constraint is inherited from constraints. The time interval is time expression used to determine whether the constraint is satisfied. Time constraint is an interval constraint that refers to a time interval. If constraints are violated, traces become negative which means that system is considered as failed.ĭuration constraint is shown as some graphical association between a duration interval and the constructs that it constrains. The semantics of a duration constraint is inherited from constraints. The duration interval is duration used to determine whether the constraint is satisfied. The destruction event is depicted by a cross in the form of an X at the end of a timeline.ĭuration constraint is an interval constraint that refers to a duration interval. Until UML 2.4 it was called destruction event, and earlier - stop. No other occurrence may appear after the destruction event on a given lifeline.Ĭomplete UML name of the occurrence is destruction occurrence specification. It may result in the subsequent destruction of other objects that this object owns by composition. It could be used in scenarios where entities undergo continuous state changes, such as temperature or density.ĭestruction occurrence is a message occurrence which represents the destruction of the instance described by the lifeline. UML also allows the state/ condition dimension be continuous. Timing diagram could show states of the participating classifier or attribute, or some testable conditions, such as a discrete or enumerable value of an attribute. It could be placed inside diagram frame or a 'swimlane'. Lifeline on the timing diagrams is represented by the name of classifier or the instance it represents. lifelines represent only one interacting entity. Lifeline is a named element which represents an individual participant in the interaction. 'The following nodes and edges are typically drawn in a UML timing diagram: lifeline, state or condition timeline, destruction event, duration constraint, time constraint.

The vector stencils library 'UML timing diagrams' contains 15 symbols for the ConceptDraw PRO diagramming and vector drawing software. The UML timing diagram example 'Inspection' was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park. For example, if the team is inspecting a software requirements specification, each defect will be text in the document which an inspector disagrees with.' In an inspection, a defect is any part of the work product that will keep an inspector from approving it. The goal of the inspection is to identify defects.

Each inspector prepares for the meeting by reading the work product and noting each defect.

A moderator is chosen to moderate the meeting. In an inspection, a work product is selected for review and a team is gathered for an inspection meeting to review the work product. Commonly inspected work products include software requirements specifications and test plans. The goal of the inspection is for all of the inspectors to reach consensus on a work product and approve it for use in the project. An inspection might also be referred to as a Fagan inspection after Michael Fagan, the creator of a very popular software inspection process.Īn inspection is one of the most common sorts of review practices found in software projects. 'Inspection in software engineering, refers to peer review of any work product by trained individuals who look for defects using a well defined process.
