5.1. More Data Design
The purpose of this chapter is to show you some of the wonderful things you can do with reports and charts, but the data model currently in place is less than challenging. You have one real master-detail relationship, with some other foreign keys used to implement data integrity.
Before you can really see what APEX reports and charts can do for you, you will have to add one more table to your schema. You will create the basic table for customer information using SQL Workshop, and then you will expand that table structure and use a script to load additional data.
Try It Out: Create Another Lookup Table
You have already created a lookup table for CATEGORIES and taken the steps required to take advantage of the table in your application. The first part of adding customer information to your schema follows the same steps:
On the next page, you will see that, by default, you have been presented with a list of all character columns for the table.
The next page prompts you for a name for the new table and the new sequence that will be used to generate IDs for the table. You will want to change these to make the names more in keeping with the naming standards in your schema.
