Description: Error handling procedures in the context of ETL (Extract, Transform, Load) are established protocols for managing and responding to errors that may arise during database operations. These procedures are essential for ensuring data integrity and quality, as well as minimizing the impact of failures in the data loading process. In an ETL environment, errors can occur at various stages, from extracting data from external sources to transforming and loading it into the storage system. Proper error handling involves identifying, logging, and resolving issues, as well as implementing recovery strategies. This may include re-running failed processes, notifying system administrators, and creating error reports for later analysis. The importance of these procedures lies in their ability to maintain business continuity, optimize system performance, and ensure that data is accurate and reliable. In cloud data warehousing environments, error handling procedures are equally critical, as they enable organizations to manage large volumes of data efficiently and effectively, ensuring that any issues that arise are addressed promptly and systematically.
