Data governance refers to processes and policies that manage the data of an enterprise. Management tasks could involve data availability, data usability, and data security. An important aspect of data governance is data lineage. Data lineage is defined as the life cycle of data. We start with the origin of the data and capture metadata at each step that the data is modified or moved. Data lineage is important for a variety of reasons. It may be an important tool for auditing your data, or perhaps a user wants to know where the figure they see in a report comes from and how it is derived.
