Exam 18: E-R Diagrams and the Idef1x Standard

The IDEF1X default cardinality of a nonidentifying connection relationship is indicated by a dashed line with a filled-in circle by the child and no other notation.

The IDEF1X equivalence of the extended E-R model subtype is the category entity,and category entities are placed in categorization clusters.

In IDEF1X,extended E-R model N:M relationships are called:

What line symbols are used in IDEF1X diagrams to represent relationships?

IDEF1X categories are put into a clutter.

In IDEF1X,extended E-R model subtype entities are called:

IDEF1X category clusters are mutually exclusive.

In IDEF1X,a category cluster includes BLACK and WHITE,which are the only possible categories.This is an IDEF1X:

Extended E-R model 1:1 relationships are called nonidentifying connection relationships in IDEF1X.

IDEF1X entities are the same as the entities in the extended E-R model.

In IDEF1X,extended E-R model 1:N relationships are called:

In IDEF1X,extended E-R model subtype entities are grouped into:

A categorization relationship is a IS-A relationship.

In IDEF1X,extended E-R model ID-dependent relationships are called:

In IDEF1X,extended E-R model weak,but non-ID-dependent relationships are called:

In IDEF1X,extended E-R model 1:1 relationships are called:

What is IDEF1X?

IDEF1X nonspecific relationships correspond to N:M relationships in the extended E-R model.

In IDEF1X,the named set of values that an attribute can have is called a:

Extended E-R model N:M relationships are called nonidentifying connection relationships in IDEF1X.
