Key Concepts in Data Discovery

Data Identification: Data discovery involves identifying data sources, locations, and formats across different systems and environments.

Metadata Analysis: Metadata, including data attributes, descriptions, and relationships, is analyzed to understand data context and usability.

Data Profiling: Profiling involves analyzing data quality, structure, patterns, and potential anomalies to assess data's fitness for use.

Data Relationships: Discovering relationships between data elements helps users understand how different data points are connected.

Data Cataloging: Data discovered during the process is often cataloged in a central repository to facilitate future access and reference.
