Choose the correct answer :
Which statement is correct about working with multiple profiles?

  1. The only way to integrate profiles is to merge them into one big profile
  2. Only profiles that represent the same domain can be integrated together.
  3. A profile can reuse all or parts of another profile, and extend other profiles.
  4. A profile can reuse all or parts of another profile, but cannot extend other profiles.

Answer(s): C

Explanation:

In UML, profiles are mechanisms to extend the UML for a specific domain or purpose. The UML specification allows for one profile to reuse or import elements from another profile. This enables modularity and encourages reusability of profile elements across different domains. Additionally, one profile may extend the stereotypes or metaclasses defined in another profile, which allows for the creation of layered profiles where each layer adds its own specificities. This is a common practice in software and systems modeling to cater to different aspects of a system within separate profiles, which are then integrated to form a comprehensive model. The capability to reuse and extend profiles is defined in the UML 2.x Superstructure Specification, which gives guidelines on how to define and use profiles within UML.

Which interpretation is valid when NamedElement A is the Supplier in a specialized Dependency having NamedElement B as the Client, and a Comment indicates that A and B participate in a transformation?

  1. B is the transformation Realization of
  2. A is the transformation Realization of
  3. A depends on B.
  4. A and B are part of an economic system where A consumes what B transforms.

Answer(s): C

Explanation:

In UML, a Dependency is a relationship that signifies that one NamedElement, the client, depends on another NamedElement, the supplier, meaning that a change in the supplier could affect the client. If NamedElement A is the supplier and NamedElement B is the client in a Dependency relationship, and there is a Comment indicating that both participate in a transformation, the interpretation is that B (the client) depends on A (the supplier) for that transformation. The comment does not necessarily change the nature of the Dependency relationship; it simply adds additional information about the nature of their interaction. A transformation could mean that B transforms A's supplied element in some way, but in terms of UML Dependency relationships, it would still be interpreted as "A depends on B" or "B requires A for its transformation". This interpretation aligns with the UML 2.x Infrastructure and Superstructure specifications, which explain Dependencies and their meanings within the UML metamodel.

Given the following fragment from a profile definition:



Which statement is correct regarding the application of the profile?

  1. A class stereotyped as an «architecture decision» must contain attributes named Complexity. Risk, and Status with the designated Enumeration types
  2. A class stereotyped as an «architecture decisions will have Stereotype Properties named Complexity. Risk, and Status with the Enumeration types designated in the profile.
  3. A class stereotyped as an «architecture decision» must contain attributes named Complexity. Risk, and Status and they may be any user-defined type.
  4. A class stereotyped as an «architecture decisions must contain exactly three attributes with user- defined names, two of which are of type Rank, and one of type Status.

Answer(s): B

Explanation:

In UML, a stereotype is a mechanism that extends the vocabulary of the UML in order to create new model elements. The given profile fragment defines a stereotype «architecture decision» that extends the metaclass Class. This stereotype includes three properties: Complexity, Risk, and Status, each typed by specific enumerations: Rank and Status.
When a stereotype is applied to a UML element, it does not create physical attributes on the element; instead, it enables the element to carry additional information as specified by the stereotype -- in this case, as Stereotype Properties. These properties are effectively tagged values that are associated with the stereotyped element. Hence, when a class is stereotyped as an «architecture decision», it will have the ability to hold values for Complexity, Risk, and Status according to the types defined by the enumerations in the profile. This is consistent with the rules defined in the UML 2.x Superstructure Specification for profiles and stereotypes.



Choose the correct answer :
Which capability Is provided by the Profile mechanism?

  1. storing user-specific configurations of model settings
  2. creating new metamodel elements for specific purposes
  3. adapting existing metamodel elements for specific purposes
  4. configuring model libraries and a set of keywords to be used for a model

Answer(s): C

Explanation:

The Profile mechanism in UML provides the capability to adapt existing metamodel elements for specific purposes. Profiles allow modelers to extend the standard UML metamodel with additional semantics by defining stereotypes, tagged values, and constraints that are specific to a particular domain, platform, or methodology. This means that profiles tailor the existing UML metamodel elements to create domain-specific models without changing the underlying metamodel itself. This adaptation mechanism is described in the UML 2.x Superstructure and Infrastructure Specifications, which detail how profiles can be used to customize the UML for particular domains or purposes.
