Students have asked these similar questions
draw an E-R diagram that indicates the entity sets and their attributes. Identify and label significant relationship sets between pairs of entities, the degree of relationship sets and the cardinality and participation constraints.
Analyze the given entity relationship diagram and answer the following questions.
What is the degree of “has” relationship?
Identify primary key(s)
Identify the category of each attribute
Name the cardinalities
In an entity-relationship diagram, what does cardinality represent? 1:The distinct identifier for which data is kept 2:The relationship's maximum number of entity instances 3:An entity's total amount of primary keys. 4:An entity's total amount of characteristics
