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.
b. Decompose the dependency diagram in Problem 11a to create table structures that are all in 3NF and write the relational schema. Make sure that you label all dependencies.
c. Draw the Crow’s Foot ERD to reflect the properly decomposed dependency diagrams you created in Problem 11b. Make sure that the ERD yields a database that can track all of the data shown in Problem 11. Show all entities, relationships, connectivities, optionalities, andcardinalities.
