Shared Association relationships manifest weak ownership semantics, where if the whole part is deleted or removed from the model, all the parts owned by the whole part will not be deleted. A Shared Association relationship is drawn as an arrow where the tail is attached to the part element, and a white diamond arrowhead is attached to the whole component element. Aggregation) relationship is a weaker form of the Part Association relationship described above. Part Association relationships manifest strong ownership semantics, where if the whole part is deleted or removed from the model, all the parts owned by the whole part will be deleted as well.Ī Shared Association (a.k.a. A Part Association relationship is drawn as an arrow where the tail is attached to the part element, and a black diamond arrowhead is attached to the whole component element. Composition) relationship is a “whole-part relationship between two model elements, where one model element is the whole component and the other end is a part of the whole component, that is “owned by” the whole component. For example, if Block A has a Reference Association to Block B with Operation mumble, an instance of Block A may potentially send a message mumble to an instance of Block B during some interaction between the two objects.Ī Part Association (a.k.a. The following kinds of Association relationships are defined in order of increasing semantics:Ī Reference Association relationship is a nondescript relationship between two model elements, which indicates that one instance of the referencing model element may invoke operations or otherwise interact with instances of the referenced model element during an interaction between the two object.

SysML supports the specification, analysis, design, verification, and validation of a broad range of systems and systems-of-systems.Systems Modeling Language (SysML): SysML is a general-purpose architecture modeling language for Systems Engineering applications. SysML is an enabling technology for Model-Based Systems Engineering (MBSE).(A UML Profile is a UML dialect that customizes the language via three mechanisms: Stereotypes, Tagged Values, and Constraints.) SysML is a dialect of UML 2, and is defined as a UML 2 Profile.These systems may include hardware, software, information, processes, personnel, and facilities. The SysML was originally created by the SysML Partners' SysML Open Source Specification Project in 2003. The SysML was adapted and adopted by the Object Management Group (OMG) as OMG SysML in 2006. The SysML is composed of nine (9) diagram types and Allocation Tables for mapping language elements across diagram types: DIAGRAM PROPERTIES For more information about the current version of OMG SysML, see the SysML FAQ: What is the current version of SysML?.
