Question

Given the sample records in the CHARTER table shown in Table P6.11, do the following:
a. Write the relational schema and draw the dependency diagram for the table structure. Make sure that you
label all dependencies. CHAR_PAX indicates the number of passengers carried. The CHAR_MILES entry is
based on round-trip miles, including pickup points. (Hint: Look at the data values to determine the nature
of the relationships. For example, note that employee Melton has flown two charter trips as pilot and one
trip as copilot.)
b. Decompose the dependency diagram you drew to solve Problem 11a to create table structures that are in
3NF and write the relational schema.
c. Draw the Crow’s Foot ERD to reflect the properly decomposed dependency diagrams you created in
Problem 11b. Make sure the ERD yields a database that can track all of the data shown in Problem 11.
Show all entities, relationships, connectivities, optionalities, and cardinalities.
