Configure business rules for customization
After you have customized the IBM Gift Center, you should also configure business rules for the custom code. You should consider the following issues when you configure business rules:
- The GRREGRULE database table, where business rules are stored
- The WebSphere Commerce configuration file, where you enable all business rules
- The commands that you should extend for the business rules
In addition, the IBM Gift Center provides methods to interpret the values within the business rules. The GiftRegistryRules.java class provides these methods.
