Before going any further, let’s figure out what’s data lineage.

### What is data lineage?

Data lineage is a concept in data governance, which is to find the connection between related data in the process of data traceability. It is a logical concept. Data lineage analysis is a word often mentioned in data governance. Data lineage is a means to ensure data fusion, and data fusion processing can be traced through data lineage analysis. In big data, data lineage refers to the link in which data is generated. In other words, it is how our data came from and what processes and stages it has gone through.

### Why do you need to trace the data in the report to the source?

In the process of data processing, from the data source to the final data generation, every link may lead to data quality problems. For example, the data quality of our data source itself is not high. If the data quality is not detected and processed in the subsequent processing links, the data information will eventually flow to our target table, and its data quality is not high, either. It is also possible that in a certain link of data processing, we have performed some inappropriate processing of the data, resulting in poor data quality in subsequent links. Therefore, for the data lineage, we must ensure that we pay attention to the detection and processing of data quality in each link, so that our subsequent data will have high data quality.

Due to the large amount of data in the enterprise, the data traceability process in reality is often complicated and difficult. Gudu SQLFlow was born to solve the above problems. It can well support the needs of such different database platforms, and can greatly improve your efficiency and accuracy in this type of work.
