Chapter 4. Data objects
Data objects are the building blocks for the rule assets that you create. Data objects are custom data types implemented as Java objects in specified packages of your project. For example, you might create a Person object with data fields Name, Address, and DateOfBirth to specify personal details for loan application rules. These custom data types determine what data your assets and your decision service are based on.
For more information about creating data objects, see "Creating data objects" in Designing a decision service using guided decision tables.
