Data and Semantic Flow

Once well managed, metadata is then open for detailed analysis, and true business level use cases may be solved. Talend Data Catalog supports full business level lineage and impact analysis down to the classifier (table/entity/dimension) and feature (column/attribute/measure) level.

Generally, there are two types of lineage: Data Flow and Semantic Flow. Talend Data Catalog can allow users to display and analyze both types of lineage.

Data flow

Based upon connection definitions to data stores and physical transformation rules which transform and move the data

Semantic flow

Detailing the relationships from a conceptual to logical Model, or a logical to physical Model.
