You should now have enough knowledge of Freedombase to create systems, excluding custom code or subroutines, and excluding customising the interface. To better embed what you have learned thus far, please work your way through the following recommendatations. Remember to rebuild the processes, and to recreate the templates, after each change, so you can test each change:

1. Add a new PRODUCT class, that contains a PRODUCT code, a DESCRIPTION, and a PRICE.

2. Add a PRODUCT attribute onto the ORDER class, that is related to the PRODUCT attribute on the PRODUCT class.

3. Derive the AMOUNT attribute on the ORDER class, by setting it to the PRICE from the PRODUCT class.

4. Once the above has been achieved, add a PRICE and a QUANTITY attribute to the ORDER class, setting PRICE from the DEMO_PRODUCT_PRICE attribute, and setting AMOUNT to PRICE*QUANTITY.

5. Once the above has been achieved, turn the PRODUCT, PRICE, QUANTITY and AMOUNT attributes into a multi dimensional table within the ORDER class, by setting PRODUCT as the controlling attribute for these attributes.

6. Play around, making other changes or improvements as you think of them. The more comfortable you are with Freedombase, the easier you will find Freedombase to use, and the easier the remaining tutorials will be.
