Identify all the important concepts represented in the library database case study described here. In particular, identify the abstraction of classification (entity types and relationship types), aggregation, identification, and specialization/generalization. Specify (min, max) cardinality constraints whenever possible. List details that will affect the eventual design but have no bearing on the conceptual design. List the semantic separately. Draw an EER diagram of the library database.
