V procese vývoja softvérového systému sa vytvárajú modely tried na troch úrovniach. Aké je poradie modelov v poradí od prvej po tretiu úroveň ?
- A.
Doménový model - konceptuálny model - implementačný model
- B.
Doménový model - implementačný model- konceptuálny model
- C.
Konceptuálny model - doménový model - implementačný model
- D.
Konceptuálny model - implementačný model - doménový model
Correct Answer
A. Doménový model - konceptuálny model - implementačný modelExplanation
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.Rate this question:

V rámci činnosti analýzy je potrebné dbať na :
- A.
Používať pojmy doménového jazyka
- B.
Používať len "prirodzenú" dedičnosť
- C.
Používať len "technickú" dedičnosť
- D.
Maximalizácia vzťahov
Correct Answer(s)
A. Používať pojmy doménového jazyka
B. Používať len "prirodzenú" dedičnosťExplanation
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.Rate this question:

Čomu je potrebné venovať zvýšenú pozornosť pri analýze podstatných mien a slovies ?
- A.
Nepresné pochopenie domény
- B.
Slovesá
- C.
Skryté triedy
- D.
Podstatné mená
Correct Answer(s)
A. Nepresné pochopenie domény
C. Skryté triedyExplanation
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.Rate this question:

Aký je rozdiel medzi typmi vzťahov agregácia a kompozitná agregácia ?
- A.
Agregácia vyjadruje silnejší vzťah medzi triedami ako kompozícia
- B.
Kompozícia vyjadruje silnejší vzťah medzi triedami ako agregácia
- C.
Agregácia vyjadruje výhradné vlastníctvo závislého objektu
- D.
Žiaden
Correct Answer
B. Kompozícia vyjadruje silnejší vzťah medzi triedami ako agregáciaExplanation
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.Rate this question:

Interakcia medzi ktorými typmi tried je NEžiadúca v sekvenčnom diagrame ? ( vyberte dve )
- A.
Actor - control
- B.
Boundary - control
- C.
Control - control
- D.
Entity - actor
Correct Answer(s)
A. Actor - control
D. Entity - actorExplanation
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.Rate this question:

Pri eliminácií tried pri prevode doménového modelu na analytický ruším :
- A.
Triedy typu entity
- B.
Triedy reprezentujúce atribúty alebo operácie
- C.
Triedy typu worker
- D.
Nerelevantné triedy
Correct Answer(s)
B. Triedy reprezentujúce atribúty alebo operácie
D. Nerelevantné triedyExplanation
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.Rate this question:

Životný cyklus jedného objektu
Correct Answer
D. Životný cyklus jedného objektuExplanation
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.Rate this question:

Ktorý(é) typ(y) vzťahov vyjadruje(ú) vzťah časť-celok medzi dvomi triedami ?
- A.
Generalizácia
- B.
Asociácia
- C.
Kompozitná agregácia
- D.
Agregácia
Correct Answer(s)
C. Kompozitná agregácia
D. AgregáciaExplanation
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.Rate this question:

Correct Answer(s)
A. Súdržnosť
C. Malá množina zodpovednostiExplanation
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.Rate this question:
