Importance of a Business Data Catalog

- A business data catalog provides broader context beyond just technical metadata.
- It enables the association between data, actions, and outcomes, leading to more efficient processes.
Technical vs. Business Data Catalogs
- Technical data catalogs focus on metadata like data types, partitions, and indexes.
- Business data catalogs focus on providing business context, such as:
- Business glossaries and taxonomies
- Metadata forms for documenting data assets
- Domains for organizing data by business units
