Chapter 26. 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 services are based on.
