The Data Understanding pillar aims to do that, allow the understanding of data. The pillar covers how data can be modelled into databases, how the data is identified by a unique value, a primary key.
The pillar then builds on this and shows you how data in tables can be linked and relationships found with primary keys and foreign keys and how these composite keys can be created if they are not saved in the database.
The pillar also covers what data definitions, glossaries and dictionaries are before covering data lineage and the issues and complexities which are contained in a data’s lineage.
