Create a table or spreadsheet containing data about two different themes (other than pets and owners). Each theme should have at least three columns, so the table will have at least six columns. Enter at least three rows of data into the table. The data should cause the following modification problems:

Problem 1: Enter data that causes an insert problem. Explain what the data is and how it causes the problem.

Problem 2: Enter data that causes an update problem. Explain what the data is and how it causes the problem.

Problem 3: Enter data that causes a delete problem. Explain what the data is, and how it causes the problem.

(You may also enter other rows of data that do not cause any problems.)
