According to an example of the present disclosure, a system and a computer-implemented method of tracing data flow are disclosed. The method includes profiling and classifying, by at least one processing device, domains based on features of columns containing data. Further, the method includes selecting a lineage analysis method that includes selecting a timestamp-based lineage method, when database tables for the domains include audit columns. The lineage analysis method includes selecting a stroboscopic-sampling based lineage method, when a semantic object and/or a column mapped to a domain is present. The lineage analysis method includes selecting a record-based lineage method, when a lineage between a source schema and a target schema is to be ascertained. The method includes executing the selected lineage method, and presenting lineage results.
