Relationship between levels

Datasets from the National Aboriginal and Torres Strait Islander Health Survey are hierarchical in nature. A hierarchical data file is a way of presenting information which describes one to many, or many to many, relationships (e.g. a person may report multiple days on which alcohol was consumed and also multiple types of alcoholic beverages on each of these days).

The following table shows the hierarchical file structure and the relationship between each level:
