  • 2. 

    An attribute that may take one or more than one value for given entity instances.

    • Composite

    • Multivalued

    • Simple

    • Derived

    • Stored

    Correct Answer
    A. Multivalued
    Explanation
    A multivalued attribute is an attribute that can have more than one value for a given entity instance. This means that a single entity can have multiple values for this attribute. For example, if we have an entity called "Student" and an attribute called "Skills", the attribute "Skills" can have multiple values such as "programming", "communication", and "leadership" for a single student.

    Rate this question:

  • 3. 

    A key that satisfies the requirements for being an identifier.

    • Composite

    • Single-value

    • Simple

    • Candidate

    • Multivalued

    Correct Answer
    A. Candidate
    Explanation
    The term "candidate" refers to a key that satisfies the requirements for being an identifier. In the context of this question, the other options such as "composite," "single-value," "simple," and "multivalued" do not specifically pertain to the requirements of being an identifier. Therefore, "candidate" is the correct answer as it aligns with the given description.

    Rate this question:

  • 4. 

    An entity that exist independently of other entity types.

    • Strong

    • Weak

    • Identifying owner

    • Partial identifier

    • Attribute

    Correct Answer
    A. Strong
    Explanation
    A strong entity is an entity that exists independently of other entity types. It has its own unique identifier and does not depend on any other entity for its existence. It can exist on its own and has its own attributes and relationships with other entities.

    Rate this question:

  • 5. 

    An attribute whose values can be calculated from related attribute.

    • Composite

    • Simple

    • Multivalued

    • Derived

    • Stored

    Correct Answer
    A. Derived
    Explanation
    A derived attribute is one that can be calculated or derived from other related attributes. It does not need to be stored separately in the database as its value can be determined based on the values of other attributes. Therefore, the correct answer is derived.

    Rate this question:

  • 6. 

    An attribute that can be broken down into small pieces.

    • Composite

    • Multivalued

    • Simple

    • Derived

    • Stored

    Correct Answer
    A. Composite
    Explanation
    A composite attribute is an attribute that can be broken down into smaller, more specific attributes. It represents a collection of attributes that are related to each other and can be further divided into sub-attributes. For example, a composite attribute "address" can be broken down into sub-attributes like street, city, state, and zip code.

    Rate this question:

  • 7. 

    An attribute that uniquely identifies individual instances of an entity type.

    • Composite

    • Single-value

    • Multivalued

    • Candidate

    • Identifier

    Correct Answer
    A. Identifier
    Explanation
    An identifier is an attribute that uniquely identifies individual instances of an entity type. It serves as a unique identifier for each entity within the entity type.

    Rate this question:

  • 8. 

    An identifier that consists of a composite attribute.

    • Identifier

    • Simple

    • Composite

    • Candidate

    • Key

    Correct Answer
    A. Composite
    Explanation
    A composite identifier is an identifier that consists of multiple attributes combined together to uniquely identify an entity. Unlike a simple identifier, which is made up of a single attribute, a composite identifier is formed by combining two or more attributes. This allows for a more precise and specific identification of the entity, as multiple attributes are taken into account. In this case, the correct answer is "composite" because it accurately describes an identifier that consists of a composite attribute.

    Rate this question:

  • 9. 

    The entity type on which the weak entity type depends.

    • Strong entity

    • Weak entity

    • Identifying owner

    • Identifying relationship

    • Identifier

    Correct Answer
    A. Identifying owner
    Explanation
    The weak entity type depends on the identifying owner. In a database, a weak entity is an entity that cannot exist without the existence of a related strong entity. The identifying owner is the strong entity that the weak entity is dependent on for its existence. It is responsible for providing the identifier for the weak entity, which is used to uniquely identify instances of the weak entity type.

    Rate this question:

  • 10.
