Data Lineage

Data lineage is about tracing the path of data from its source to its final form, including any transformation it undergoes. This traceability is critical to ensuring data integrity, simplifying audit trails and complying with regulatory requirements.

The essence of data sequencing

  1. Metadata management: The key to effective data lineage, which includes documenting data attributes and transformations.

  2. Data mapping: This includes creating visual representations to understand how data moves and changes between systems.

  3. Version control: Essential for tracking different versions of data, which is critical for historical analysis.

  5. Implement a data catalogue: Include data lineage information so users can easily access and understand it.

Selection of data lineage tools

  1. Broad accessibility of data sources: Tools should be able to access and analyse a wide range of data sources.

  2. Centralised metadata aggregation: Essential for effective data management.

  3. Visual data flow mapping: Helps to easily track and understand data movement.

  4. Dynamic monitoring capabilities: Enables thorough tracking of data changes in both directions.

Data provenance challenges and solutions

  1. Granularity decisions: Determining the right level of detail is critical.

  2. Standardisation issues: Challenges with internal and external data customisation.

  3. Diverse data sources and transformations: Managing different data environments requires versatile tools.

  4. Regular lineage updates: Maintaining up-to-date lineage information to avoid inaccuracies.
