OMG OMG-OCUP2-ADV300 Exam Actual Questions

In UML, modeling individual things (such as instances) involves making statements about them. Here are the details for each option:

A . A UML Model can contain individual things (e.g. Instances) UML does not prescribe the level of detail to be used in the description.

This statement is partially correct. UML models can indeed contain individual things (instances), but the level of detail is not explicitly prescribed by UML. However, the statement does not cover the possibility of incomplete or imprecise information.

B . A UML Model can contain statements about individual things If a thing is an instance of a Classifier, these statements must be consistent (all mandatory Properties must be defined, all Constraints must be satisfied).

While it is true that a UML model can contain statements about individual things (instances), the requirement for consistency (mandatory properties and constraints) is not explicitly mentioned in UML. Therefore, this option is not entirely accurate.

C . A UML Model can contain statements about individual things These statements can be incomplete, imprecise, and abstract, but not wrong.

This statement is also partially correct. UML allows for incomplete, imprecise, and abstract statements about individual things. However, it does not guarantee that these statements cannot be wrong.

D . A UML Model can contain statements about individual things. These statements can be incomplete, imprecise, abstract, may turn out to be wrong, or even be asserted as counterfactual.

This option provides a more accurate representation. UML allows for statements about individual things that can be incomplete, imprecise, abstract, and even potentially incorrect. It acknowledges the uncertainty and variability in modeling individual things.

E . A UML Model can only contain statements about sets of individual things (e.g. Classifiers).

This statement is incorrect. UML models can contain statements about both individual things (instances) and sets of things (classifiers).

UML 2.5.1 Specification

While the UML specification does not explicitly state the options, it provides the foundation for UML modeling principles and allows for flexibility in expressing statements about individual things.

Remember that UML is a modeling language, and its primary purpose is to capture and communicate information about systems and their components. The level of detail, precision, and correctness can vary based on the modeling context and the specific use case. Therefore, option D best reflects the UML approach to modeling individual things.

Please note that the information provided here is based on UML 2.5.1, and it's essential to consult the official UML specification for the most accurate and up-to-date details.

The term ''computationally complete'' in the context of fUML refers to a subset of UML that is expressive enough to define models that can be executed automatically by a computer using an execution tool.This means that the subset includes all the necessary elements and constructs to specify the behavior of a system in a way that can be understood and run by a machine without further interpretation

The reason for fUML to be compact is to facilitate the definition of clear semantics. A smaller, more focused subset of UML allows for a more precise and unambiguous specification of the execution semantics.This clarity is essential for ensuring that models are executed consistently and as intended across different tools and platforms2. The compact nature of fUML helps in achieving this goal by limiting the scope to the essential elements necessary for execution, thereby reducing complexity and potential for misinterpretation.

The scope of fUML (Foundational UML) is to define execution semantics for a subset of the UML 2 metamodel that provides a shared foundation for higher-level UML modeling concepts.This includes the precise definition of the execution semantics of that subset, which is intended to be used by a wide range of system types, including physically distributed and concurrent systems without assumptions about global synchronization1.

fUML (Foundational UML) is a subset of the standard Unified Modeling Language (UML) that includes standard, precise execution semantics. This subset encompasses typical structural modeling constructs of UML such as classes, associations, data types, and enumerations, as well as the ability to model behavior using UML activities composed from a set of primitive actions.Therefore, a model constructed in fUML is executable in the same sense as a program in a traditional programming language, but with the level of abstraction and richness of expression of a modeling language2.
