Choose the correct answer : Which technique does Abstraction incorporate?

  1. agile modeling
  2. information hiding
  3. complexity coupling
  4. context-driven decision making

Answer(s): B

Explanation:

Abstraction in UML and software modeling often incorporates the technique of information hiding. Information hiding is a principle that supports abstraction by ensuring that unnecessary details about software components are not exposed to other parts of the system. This encapsulation strengthens modularity and keeps various parts of the program independent of one another, which simplifies complexity in large systems. Abstraction and information hiding are closely related; abstraction focuses on the high-level structure of the system, while information hiding protects the internal states and functionality of components, allowing changes without extensive impact on other system parts.

What is the defining characteristic of a domain model?

  1. It is a model that is specified using UML diagrams.
  2. It is a model that focuses on the domain requirements of the system
  3. It is a model that captures the main domain concepts and their relationships.
  4. It is a model that represents the domain architecture of the implementation of the system.

Answer(s): C

Explanation:

A domain model's defining characteristic is that it captures the main domain concepts and their relationships. This model focuses on representing the key elements within the problem domain, outlining how these elements interact with each other without detailing the specific implementations. The domain model is an essential tool in software development for understanding and communicating the fundamental structure of the system from a problem domain perspective, helping teams to design solutions that are well-aligned with actual domain needs. UML is often used to represent domain models due to its capability to visually and clearly model complex relationships and structures.



Choose the correct answer :

Which characteristic should apply to any useful model?

  1. It is specified in UML.
  2. It is platform independent.
  3. It abstracts away irrelevant detail.
  4. It is specified using a visual notation.

Answer(s): C

Explanation:

A key characteristic that should apply to any useful model, including those created with UML, is that it abstracts away irrelevant details. This abstraction is crucial for managing complexity by focusing on the essential aspects of the system that are relevant to the current perspective or analysis task. By removing unnecessary information, the model remains understandable and manageable, even as the underlying system grows in complexity. This principle helps maintain a clear and concise representation of the system, enabling stakeholders to focus on strategic decisions without being overwhelmed by details.



Choose the correct answer :

Which category of stakeholders should have prime responsibility for making decisions on the contents of a domain model, and why?

  1. The customers, as they will own the system when it is delivered
  2. The users, as they will be using the system when it is operational.
  3. All involved stakeholders, as they are knowledgeable and concerned.
  4. The development team, as they are responsible for the final implementation.
  5. Project managers, as they are responsible for delivering the right product to the customer
  6. The testing team, as test-driven design is proven to be an effective approach to development
  7. The system architects, as they are responsible for the design of the system and its proper functioning.

Answer(s): B

Explanation:

In the development of a domain model, the prime responsibility for decision-making should ideally rest with the users, as they are the ones who will be using the system operationally. Users have the most direct and frequent interactions with the system, making them best positioned to provide relevant insights into what the system should do and how it should behave to meet their needs effectively.
While other stakeholders such as customers, project managers, and developers play significant roles, the users' intimate knowledge of the domain processes and their requirements make them key contributors to ensuring that the domain model aligns closely with real-world application and utility.



Choose the correct answer :

Which UML term pair captures complementary ways of looking at a relationship?

  1. include / extend
  2. use / implement
  3. dependency / trace
  4. aggregation / composition
  5. generalization / specialization

Answer(s): D

Explanation:

The UML term pair that captures complementary ways of looking at a relationship is "aggregation / composition". Both terms describe types of associations between classes but differ in the degree of ownership and lifecycle dependency between the involved objects. Aggregation implies a weaker relationship where the parent class contains or is linked to other classes but does not strictly control their lifecycle (e.g., a university and its students). Composition, on the other hand, implies a stronger relationship where the parent class has full responsibility for the lifecycle of the associated classes (e.g., a house and its rooms). Understanding these relationships helps model systems more accurately in terms of object ownership and lifecycle management.
