Question

Technical lineage is the documentation of the following:

a) Physical tables, columns, schemas
b) Data sets used for reporting
c) Databases where the data is stored
d) Detained transformations such as ETL

Answer 1

Technical lineage is the documentation and tracking of elements in a data system such as physical tables, columns, schemas, data sets, databases, and transformations like ETL.

Step-by-step explanation:

Technical lineage refers to the documentation and tracking of various elements in a data system. These elements include physical tables, columns, schemas, data sets used for reporting, databases where the data is stored, and detailed transformations such as ETL (Extract, Transform, Load) processes.

For example, in a large data system, technical lineage would involve keeping track of which tables and columns contain specific information, what datasets are used for reporting purposes, which databases store the data, and how the data is transformed during the ETL process.

By documenting technical lineage, organizations can ensure data accuracy, traceability, and understand the flow of data within their systems.
