Consider the following relational database for the Central Zoo. Central Zoo wants to maintain information about its animals, the enclosures in which they live, and its zookeepers and the services they perform for the animals. In addition, Central Zoo has a program by which people can be sponsor of animals. Central Zoo wants to track its sponsors, their dependents, and associated data. Each animal has a unique animal number, species, name (Jumbo, Fred, etc.), gender, country of birth, and weight. Enclosures have a unique enclosure number, type (cage, fenced field, etc.), location, size, and date built. An animal can live in only one enclosure. An enclosure can have several animals in it, or it can be currently empty. A zookeeper has a unique employee number, employee name, title, and year hired. Some zookeepers supervise other zookeepers. Every animal has been cared for by at least one, and generally many zookeepers; each zookeeper has cared for at least one and generally many animals. Each time a zookeeper performs a specific, significant service for an animal the service type, date, and time are recorded. A sponsor sponsors at least one and possibly several animals. An animal may have several sponsors or none. A sponsor has a unique sponsor number, a name, address, and telephone number. For each animal that a particular sponsor sponsors, the zoo wants to track the annual sponsorship contribution and renewal date. In addition, Central Zoo wants to keep track of each sponsor's dependents, keeping their name, relationship to the sponsor, and date of birth. A sponsor may have several dependents or none. A dependent is associated with exactly one sponsor. Central Zoo Entities ENCLOSURE Relation ANIMAL Relation ZOOKEEPER KeIaIION SFUNSUN meIa IUMI QUNIKIBUIIN KeIaUON g.
