An EMP relation contains the following fields for each employee tuple: EID: integer, EName: string, Age: integer, Salary: integer Assume that an integer occupies 4 bytes and a character occupies 1 byte. Consider the INSERT statement below: INSERT INTO EMP VALUES (123456, 'Kathleen', 32, 89000); Answer each of the following questions: (1) Assume that fixed-length record organization is used, and the field EName is stored using 25 characters. How many bytes are required to store the above inserted record? Show your calculation process and result. (2) Assume that variable-length record organization is used, and a special character is used to represent the end of EName in each employee tuple. How many bytes are required to store the above inserted record? Show your calculation process and result.
