Consider the Happy Cruise Lines relational database in Minicase 5.1.The company has decided to reconfigure this database as a distributed database among its major locations: New York, which is its headquarters, and its other major U.S. ports, Miami, Los Angeles, and Houston. Distributed and replicated among these four locations, the tables have the following characteristics:

SHIP consists of 20 records and is used in all four cities.

CRUISE consists of 4,000 records. CRUISE records are used most heavily in the cities from which the cruise described in the record began.

PORT consists of 42 records. The records that describe Atlantic Ocean ports are used most heavily in New York and Miami. The records that describe Caribbean Sea ports are used most heavily in Houston and Miami. The records that describe Pacific Ocean ports are usedmost heavily in Los Angeles.

PASSENGER consists of 230,000 records and is primarily used in New York and Los Angeles.
