Test 7. - Analýza A Návrh Tried

The correct answer states that "Kompozícia vyjadruje silnejší vzťah medzi triedami ako agregácia" which translates to "Composition expresses a stronger relationship between classes than aggregation." This means that composition is a type of relationship where one class is composed of another class and is dependent on it, while aggregation is a weaker form of relationship where one class is associated with another class, but the associated class can exist independently. Therefore, the correct answer explains the difference between the types of relationships aggregation and composition.

The correct answer is "Analýza a návrh." A conceptual model of a system is created during the analysis and design phase of the development process. This phase involves understanding the requirements of the system and designing a solution that meets those requirements. The conceptual model helps to visualize and define the structure and behavior of the system before implementation.

The correct answer is "Životný cyklus jedného objektu" which translates to "Lifecycle of one object." A state diagram represents the different states and transitions that an object goes through during its lifecycle. It shows how an object changes state in response to events or actions in the system. Therefore, the correct answer is the one that relates to the lifecycle of an object.

The given statement is false. An analytical class is not a class that captures software and hardware details of a system. It is not clear what an analytical class refers to in this context, but it is not related to capturing software and hardware details.

The correct answer for this question is "Kompozitná agregácia, Agregácia". These types of relationships express the part-whole relationship between two classes. In a composition aggregation, one class is composed of other classes and has exclusive ownership over them. In an aggregation, one class is associated with another class, but does not have exclusive ownership over it. Both of these types of relationships are used to represent the relationship between a whole and its parts in object-oriented programming.

The correct order of the models in the software system development process is: domain model - conceptual model - implementation model. This means that the domain model is created first, followed by the conceptual model, and finally the implementation model. The domain model represents the real-world domain of the software system, the conceptual model represents the abstract and high-level design of the system, and the implementation model represents the actual implementation details of the system.

It is necessary to pay increased attention to the analysis of nouns and verbs due to the following reasons:
1) Nepresné pochopenie domény (Misunderstanding of the domain): This implies that if there is a lack of understanding or incorrect interpretation of the subject or topic being analyzed, it can lead to inaccurate conclusions or interpretations.
2) Skryté triedy (Hidden classes): This suggests that there may be hidden or underlying patterns or categories within the nouns and verbs that need to be identified and analyzed in order to gain a comprehensive understanding of the language.

The correct answer is "Len primárne atribúty a operácie, Nemusí mať definované žiadne atribúty ani operácie." This means that an analytical class may contain only primary attributes and operations, or it may not have any attributes or operations defined at all.

The correct answer is "Dynamický." The given options represent different types of models, and "Dynamický" refers to the dynamic model. A dynamic model represents the behavior and interactions between different components or objects in a system over time. It focuses on how the system changes and responds to various events or inputs. Therefore, the correct answer is "Dynamický" because it is the type of model depicted in the sequence diagram.

The correct answer is "Hraničné, entitné, riadiace". This is because the RUP (Rational Unified Process) stereotype method divides classes into three categories: boundary, entity, and control.

In a sequence diagram, the interaction between "actor - control" and "entity - actor" types of classes is undesirable. This means that the communication between an actor and a control class, as well as between an entity and an actor class, is not intended or preferred in this context. The diagram should ideally avoid these types of interactions to ensure a clear and efficient representation of the system's behavior.

The correct answer is "Triedy reprezentujúce atribúty alebo operácie, Nerelevantné triedy". This is because when converting a domain model to an analytical model, we need to eliminate irrelevant classes and focus only on the classes that represent attributes or operations. The classes that represent attributes or operations are important for understanding the behavior of the system, while irrelevant classes do not contribute to the analysis and can be safely removed.

The correct answer is "Rozdelenie systému na podsystémy" because it is not a part of the design of classes. The other options, such as converting analytical classes into designs, defining operations and properties of classes in detail, and defining relationships between classes, are all important aspects of class design. However, dividing the system into subsystems is not specifically related to the design of classes.

In the context of analysis, it is important to use terms from the domain language and to use only "natural" inheritance. This means that when analyzing a problem or system, it is crucial to use terminology that is specific to the domain or field in which the analysis is being conducted. Additionally, it is important to consider and utilize only the inheritance that is inherent or natural to the problem or system being analyzed, rather than introducing unnecessary or unrelated concepts. By doing so, the analysis can be more accurate and relevant to the specific context.

During the design process, a significant emphasis is placed on interfaces, class analysis, creating a domain model, and a concise, general system design. The correct answer, "na rozhrania" (on interfaces), aligns with this emphasis and suggests that interfaces play a crucial role in the design process.

The correct answer is "Súdržnosť" and "Malá množina zodpovednosti". These two properties are suitable for the analytical class because they emphasize the importance of coherence and consistency in the analysis process. "Súdržnosť" refers to the ability to maintain logical connections and relationships between different components of the analysis, ensuring that they work together harmoniously. "Malá množina zodpovednosti" means having a small set of responsibilities, which helps to ensure clarity and focus in the analysis, avoiding confusion and overlapping tasks. These properties are crucial for conducting effective and accurate analysis.

The correct answer includes three sources that can be used to identify analytical classes: specifications of requirements, realization of use cases, and domain model. These sources provide information and insights into the system's requirements, use cases, and the domain in which the system operates. Analytical classes can be identified by analyzing and understanding the information provided by these sources.

The correct answer is to optimize the association relationships, which include N-ary associations, irrelevant associations, and associations representing implementation.

The correct answer is "Diagram balíčkov, Stavový diagram, Diagram tried". These three diagrams are commonly used in software analysis. The "Diagram balíčkov" (Package diagram) is used to visualize the structure of a system and its dependencies. The "Stavový diagram" (State diagram) is used to model the behavior of a system or a class in terms of states and transitions. The "Diagram tried" (Class diagram) is used to represent the static structure of a system, showing classes, attributes, methods, and their relationships.
