Data model for Watson Knowledge Catalog reporting
The data model that you can use to create SQL queries to generate reports on Watson Knowledge Catalog data.
Using the data model
To explore the relationships in the data model, you can create an interactive Entity Relation Diagram (ERD file). Relation diagrams represent the actual state of databases and you cannot save any changes that you make. To create an ERD file, connect your data mart to a database tool of your choice and follow the tool's instructions.
