Data integration transforms transactional data into analytical formats. Automation removes manual extraction risks and ensures data completeness.
ETL vs. ELT Processing
  • ETL (Extract, Transform, Load): Data is extracted from source systems, transformed in a staging area to match a strict target schema, and loaded into a data warehouse. This is ideal for sensitive financial reporting requiring data masking prior to storage.
  • ELT (Extract, Load, Transform): Raw data is directly loaded into a high-performance cloud data platform, and transformations occur on-demand using the target database’s compute power. This supports scalable data exploration.

Automation & Validation
  • Orchestration: Tools like Apache Airflow manage dependencies, schedule extraction intervals, and handle pipeline failures automatically.
  • Data Reconciliation: Automated check-sum and row-count validations compare source records to target destination tables to detect data drops.
