Exam 4: Data Modeling and the Entity-Relationship Model

The number of entity classes involved in a relationship is known as the relationship's:

Microsoft Access 2013 uses banded form and report editors.

Relationships with the degree 2 are often called ________ relationships.

In the Entity-Relationship data model,all instances of an entity of a given type are grouped into:

Which of the following is not a stage in the development of a database system?

Distinguish between an entity class and an entity instance.

The representation of the content,relationships,and constraints of the data needed to support the system requirements is the:

Maximum cardinality indicates whether or not an instance of one entity class must be related to at least one instance of another entity class.

In crow's foot E-R notation,a circle indicates a minimum cardinality of zero.

Microsoft Access 2013 can be used to build a prototype database,which allows users to validate the data model by demonstrating the consequences of data modeling decisions.

The Microsoft Access 2013 report editor is a(n):

Microsoft Access is a good tool for creating mock-ups of forms and reports because:

Microsoft Access 2013 database files can be easily copied to create multiple copies of a database.

Microsoft Access 2013 can be used to prototype databases for ________.

In crow's foot style E-R diagrams,an entity class is represented by a(n)________.

The E-R Model assumes that all instances of a given entity class have the same attributes.

During the design phase of developing a database system,the users are asked about the need for changes to existing forms and reports.

Use cases can be used to validate the data model,design,and implementation.

When developing a database system,the database is constructed during the implementation phase.

When an entity class has a relationship with itself,it is called a(n)________ relationship.
