Assume that the records of the Crew Member file are physically stored in the order shown. i. Retrieve all of the records of the file physically sequentially ii. Retrieve all of the records of the file logically sequentially based on the Sailor Name field. iii. Retrieve all of the records of the file logically sequentially based on the Sailor Number field. iv. Retrieve all of the records of the file logically sequentially based on the Ship Number field. V. Perform a direct retrieval of the records with a Sailor Number field value of 27467 vi. Perform a direct retrieval of the records with a Ship Number field value of 020 vii. Perform a direct retrieval of the records with a Job Title field value of Captain. The value 009 appears as a ship number once in the SHIP table and four times in the CREW MEMBER table. Does this constitute data redundancy? Explain. c. d. Merge the SHIP and CREW MEMBER tables based on the common ship number field (in a manner similar to Figure 3.8 for the General Hardware database.) Is the merged table an improvement over the two separate tables in terms of: i. Data redundancy? Explain. ii. Data integration? Explain. e. Explain why the Ship Number field is in the CREW MEMBER table f. Explain why ship number 012 appears three times in the CREW MEMBER table How many tables must be accessed to find: i. The year that ship number 012 was built? ii. The home country, of sailor number 27941? iii. The name of the ship on which sailor number 18535 is employed? g. h. Describe the procedure for finding the weight of the ship on which sailor number 00536 is employed i. What is the mechanism for recording the one-to-many relationship between crew members and ships in the Happy Cruise Lines database, above
