Consider the employee work-team example, and assume that certain employees participate in more than one work team . A given employee may therefore appear in more than one of the team entity sets that are lower level entity sets of employee. Thus, the generalization is _____________.
A. Overlapping
B. Disjointness
C. Uniqueness
D. Relational
Answer:A
Consider the employee work-team example, and assume that certain employees participate in more than one work team . A given employee may therefore appear in more than one of the team entity sets that are lower level entity sets of employee. Thus, the generalization is _____________.
A. Overlapping B. Disjointness C. Uniqueness D. Relational
Explanation:In overlapping generalizations, the same entity may belong to more than one lower-level entity set within a single generalization.
