Possible Answers

1. create database addressbook;
   
   OR
   
   CREATE DATABASE addressbook;
   

   Note: SQL statements are case-insensitive, though table names and database names might be sensitive to case depending on the platform.

2. The DESCRIBE statement as in

   DESCRIBE employee_data;
   

3. SHOW DATABASES; (at the mysql prompt)

4. INSERT INTO employee_data
   (f_name, l_name, title, age, yos, salary, perks, email)
   values
   ("Rudolf", "Reindeer", "Business Analyst", 34, 2, 95000, 17000, "rudolf@bignet.com");
   

   Note: The text strings are enclosed in quotes.

5. SELECT emp_id, f_name, l_name, title, age, yos, salary, perks, email from employee_data;
   
   OR
   
   SELECT * from employee_data;
   

   The second form is better and easier to type.

6. This displays the data from columns f_name and email.
