Check your understanding Do these joins by hand, without a computer. Join a row of Table 1 with a row of Table 2 if the first letters are the same. Show all the rows of both tables, even if they do not have a matching row in the other table. Create the result table and state if this is a one-to-one relationship in the mathematical sense or in the database design sense.

For SQL code. This section is about joining two tables with an inner join. How would this/these tables turn out given the Check Your Understanding instructions. 

13-3 A one-to-one relationship This section shows a model case of combining two tables with an inner join. This shows the technique that is always used, but avoids the complexities, which we discuss later. For now, just focus on this simple example. Rows from one table are matched with rows from the other table. There are no hidden links between the two tables. The data in the tables determine how to combine the rows. One column is chosen from each table. When these columns have the same value, the rows are combined.
