DMN elements

	Decision – a node in which one or more input elements determine the output based on decision-making business logic defined as an expression or table.
	Input data – information used in a decision node or business knowledge model. Input data usually includes business-level concepts or objects related to the business. For example, credit applicant data from a customer application.
	Knowledge source – external entities, documents, committees, or policies that govern the decision or business knowledge model. Knowledge sources are references to real-world factors, not executable business rules. For example, a loan application.
	Business knowledge model – a reusable function with one or more decision elements. Decisions that share the same logic but depend on different supporting inputs or decisions use business knowledge models to determine which procedure to follow.
