Exam 7: Structuring System Requirements: Conceptual Data Modeling

The minimum number of instances of entity B that may be associated with each instance of entity A defines the:

On an entity-relationship diagram, the entity's identifier is:

A renewal is an example of a(n):

Book, supplier, and state are examples of entity types.

A set of two or more multivalued attributes that are logically related defines:

Asking system users and managers, "Who is responsible for establishing legitimate values for these data?" helps determine:

The goal of conceptual data modeling is to capture as much of the meaning of data as possible.

A plural relationship is a relationship that the data modeler chooses to model as entity type.

A "many" maximum cardinality is noted on the E-R diagram by:

The minimum requirements for a new system are also its mandatory features.

An attribute that can have more than one value for each entity instance is referred to as:

Use a verb or verb phrase to name an entity.

When selecting an identifier, one should choose a candidate key that will not change its value over the life of each instance of the entity type.

An attribute (or combination of attributes) that uniquely identifies each instance of an entity type defines:

A product is an example of a(n):

During which of the following steps will you bring the current phase to a close, prepare a report and presentation to management concerning continuation of the project, and get ready to move the project into design?

A relationship must be turned into an associative entity when the associative entity has other relationships with entities besides the relationship that caused its creation.

If STUDENT and COURSE participate in a relationship, this is an example of a(n):

The minimum requirements for the new system are called:

The top-down approach to data modeling derives a data model by reviewing specific business documents.
