What is a data catalog?
A data catalog is a centralized repository that serves as a comprehensive index of an organization's data assets. It provides a searchable inventory across multiple systems, helping users quickly locate, understand, and analyze data. By leveraging metadata, a data catalog supports data governance and ensures that data is well-organized, accessible, and trusted.
A typical data catalog includes metadata about:
Data source: Where the data originates (e.g., databases, data lakes, cloud storage)
Data types: The structure and format of the data (e.g., structured, unstructured, semi-structured)
Data lineage: How the data has moved and transformed over time (e.g., ETL processes, data transformations)
Data quality: Metrics that assess the accuracy, completeness, and consistency of the data
Data governance: Information on ownership, stewardship, and access policies
By consolidating this information, a data catalog simplifies data discovery, supports more effective data governance, and enables organizations to maximize the value of their data.
