What is audit table typology in etl batch processing?

[jatin]

I'm working with ETL batch processes and came across the term "audit table typology." Can someone explain what it means, how audit tables are structured, and why they are important for data validation and tracking in ETL pipelines?

Audit table typology in ETL batch processing refers to the structured use of control tables to monitor and log data workflows. It includes batch control, job-level, source-target, and error logging tables. These help ensure data integrity, enable traceability, support error handling, and enhance overall process transparency.
