Glossary of Terms

A component of a code value. Code values have two or more attributes.

A grouping of reference data that comes from the same application, industry standard list, or internal list. You organize code lists into reference data sets.

A unique value, such as a business term. A code value is the lowest representation of reference data. You create code values in code lists.

A visual representation of a one-way relationship between code values in a pair of code lists. Crosswalks exist between a pair of code lists in the same reference data set.

A code list that contains code values that depend on code values from a code list in a different reference data set.

A reference data set that depends on code values in another reference data set. Code lists inherit the dependency from the reference data set.

A code list that supports hierarchical data structures. You can arrange its code values into levels to create hierarchies.

A reference data set that supports hierarchical data structures. Code lists inherit the hierarchical structure from the reference data set. You can arrange code values in a hierarchical reference data set into levels to create hierarchies.

An arrangement of code values from multiple code lists below, above, or at the same level as other code values. The code values that you can arrange depend on the hierarchy model.

For example, you might have a hierarchy model with the Region code list defined as the top level node and a relationship from the Region code list to the Country code list. Then in the hierarchy, you can create a hierarchy relationship from the North America code value to the United States code value. You might also create a hierarchy relationship from the North America code value to the Canada code value.

A model in which nodes are organized into a tree-like structure. A hierarchy model contains a top-level node, child nodes, a relationship from the top-level node to a child node, and relationships from child nodes to other child nodes. Each node in the model corresponds to a code list.

For example, you might create a location hierarchy. In the hierarchy model, you define the Region code list as the top-level node. You add the Country code list as a child node and then create a hierarchy model relationship from the Region node to the Country node.

A logical grouping of reference data. A reference data set represents a category of reference data and acts as a template and container for code lists.

The process of creating a one-way relationship between code values in the source code list and code values in the target code list. Value mappings provide a way to translate code values in the source code list to code values in the target code list.
