  2. JOIN Types on Relationships • There will be instances in your queries where you will want results from a table even if they have no corresponding entries in another table. • By manipulating the JOIN types on the relationships in your queries, you can achieve this goal.

  3. JOIN Types on Relationships • Create a query to count the number of each albums for each genre in the music database. • What do you notice about the number of results from the query and the number of genres actually defined in the Genre table?

  4. JOIN Types on Relationships • Option 2 will create a LEFT JOIN • Will force all entries from the left table to appear • Option 3 will create a RIGHT JOIN • Will force all entries from the right table to appear Left table Right table

  5. JOIN Types on Relationships • Run the query again and take note of the number of results

  10. Form Creation • Forms, like tables and queries, have different views • Layout view allows you to reposition elements within your form • Design view lets you modify and add complex form controls, change themes, and modify other visual characteristics.

  11. Form Creation • Forms can be created for multiple data sources • Let’s create a form to perform data entry for both the Genre and Albums tables • From the Genre table, add Genre Name and Description • Add all fields from the Albums table • View form by Genre • Forms of this type are known as “One-To-Many forms” or “Mainform/Subform configuration”

  12. Reports • Reports are created in a very similar manner to forms, but are primarily used for outputting information in a logical manner
