Good data mapping tools streamline the transformation processby providing built-in tools to ensure the accurate transformation of complex formats, which saves time and reduces the possibility of human error. Data mapping is a set of instructions that merge the information from one or multiple data sets into a single schema (table configuration) that you can query and derive insights from. For even more details, check out this more in-depth wikipedia article on data lineage and data provenance. And different systems store similar data in different ways. When it comes to bringing insight into data, where it comes from and how it is used. When you run a query, a report, or do analysis, the data comes from the warehouse.
