▪What are tables, rows, and columns?
▪How do I create a table?
▪How do I put data into a table?
▪How do I update data in a table?
▪How do I delete data from a table?
▪How do I list data in a table?
▪How do I list related data in two different tables?
▪How do I ensure that multiple statements are executed together (so that all fail or all succeed as a group)?
