Most organizations are managing large volumes of information from multiple data sources. To stay competitive, businesses must efficiently organize, discover, and use their data assets. A data catalog acts as an organized inventory of an organization’s data, enabling teams to find, understand, and manage data more effectively. This guide covers the essential aspects of data catalogs, their benefits, best practices for implementation, and real-world case studies showcasing how Secoda’s data catalog tool has supported companies across various industries.

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.
