What is a Fact Concept?
Fact concept is an abstract model that defines the fundamentals of knowledge in a specific context. Facts describe what business people know about their business. A Fact has certain characteristics: structure, relationships, and constraints. The Fact Concept visually describes these characteristics. When Fact Concept is modeled, it defines:
- The context of a business domain
- Bases of the business glossary (terms) and associated expressions
- Constraints about Facts, structurally and semantically
- Relationships of the Facts within a business context
There are three major elements in a Fact.
A fact is a logical grouping of data and/or information that represents a concept. In this example, Person is the fact which has three members FirstName, LastName, and Occupation.
A list of valid pre-defined values for a member of a Fact. In this example, it’s the occupation which has a list of options.
A relationship defines the whole-part relationship between Facts and Options. It can define one-to-one, one-to-many and many-to-one relationships.
To add a new Fact Concept document,

Once you add facts and options, this will be the window.
