8.1.1.2.2.1 Subject Area Glossary
Each Subject Area has a pre-defined glossary that provides essential documentation for users, helping them understand data structure and relationships.
- List of all result entities included in the subject area
- Entity granularity of each result entity based on the primary keys
- Attribute name and detailed attribute description for all primary keys
- Entity relationships that define relation of attributes with related dimension entity and the related attribute
The glossary helps users determine which attributes can be combined in a single visualization for meaningful insights. A single visualization should include attributes of similar granularities to avoid Cartesian join issues, which can lead to data misinterpretation.
For Example:
Attributes from Common Account Summary and Loan Account
Summary can be used together in a single visualization.
Subject Area Glossary can be accessed as below:
- End of Period Balance (EOP Bal) for loans should not be combined across Account Rating Details and Common Account Summary.
- If an account has three credit ratings from different agencies, it will have three rows for the same account, repeating the EOP Bal value.
- This could lead to the EOP Bal being aggregated incorrectly (e.g., tripled for a single account).
