Profiling Considerations & Profiling (Data Discovery) in EDC

Data profiling is the process of reviewing source data, understanding structure, content, and interrelationships, and identifying potential for data projects 
When you enable data discovery for a resource and scan the resource, the Enterprise Data Catalog identifies profiling-related metadata, such as null values, distinct values, inferred data types, unique keys, and data domains in the resource. 
When you create a resource, choose the Metadata Load Settings > Data Discovery > Enable Data Discovery option to discover profiling-related metadata and unique keys. Based on your requirements, you can configure domain connection settings, basic profile settings, unique key inference settings, and column similarity settings.
