Data lineage is a methodology that tracks a data's entire journey through the business pipeline, providing a visual representation of all the places the data has been in the system. It helps companies improve root cause analysis, optimize regulatory compliance, and allocate resources more efficiently by focusing on validating data accuracy and consistency. Data catalogs, on the other hand, are structured inventories of all data assets collected in an organization, enabling users to find and access relevant data quickly and easily. They eliminate data wrangling, promote collaboration, and improve data discoverability, providing detailed descriptions of data assets and automated contextualization of data. While data lineage is ideal for tracing data flow for modeling, migration, compliance, or troubleshooting, data catalogs are better suited for facilitating data discovery, metadata management, and collaboration for data analysis.
