Data Catalog: What It Is and How to Implement It

A data catalog is an organized inventory of data assets within an organization that helps users find and manage data resources by providing rich metadata and context about these assets. It includes data sources, formats, quality, and usage policies, giving users confidence to locate, understand, and utilize data across the organization. Key features of a robust data catalog include metadata management, data lineage, data governance, search and discovery, collaboration, automated data profiling, and integration with other data management tools and platforms. Implementing a data catalog can enhance data discoverability, improve data quality, increase productivity, support better decision-making, and save costs by optimizing data management processes.
