Let's practice managing tables

“

- [Scott] Managing a database involves many different tasks, like defining and constructing tables, making changes to existing tables, adding records to tables and retrieving records, and transforming the information they contain. Sometimes these tasks are handled by specialized tools and sometimes they're tasks that are divided up between various roles, which are each responsible for different areas of the overall database management and activity.

Let's go.
