The database stores all configurations, such as business rules, UI policies, and contextual security rules in addition to all the data, such as users, groups, and tasks. And while Chapter 7, Exchanging Data – Import SetsImport Sets, Web Services, and Other Integrations, showed how data can be exported to CSV and Excel, those formats don't typically contain all the information of every field.

Each field in the record is represented as an element, and the action attribute specifies what should happen when the data is read. As a truncated example, a business rule may be serialized as follows:
