• B. Evaluate, Translate, Load; common tools: Informatica, Talend, SSIS, DataStage, Oracle Data Integrator; ensure data quality and transformation rules.
• C. Export, Transform, Link; common tools: Oracle Data Integrator; ensure data transformation.
• D. Encrypt, Transform, Log; common tools: none.

Answer: (A)

ETL stands for Extract, Transform, Load. In ERP projects, ETL is the process of pulling data from various source systems (ERP modules and other applications), cleaning and shaping it to meet business rules and formats, and loading it into a target data store such as a data warehouse or data mart used for reporting and analytics. The extract phase collects data from sources, the transform phase enforces data quality, normalization, rule‑based changes, and format harmonization, and the load phase writes the prepared data to the destination with considerations for incremental updates, auditing, and error handling. This flow enables unified, accurate reporting across finance, procurement, manufacturing, and sales within an ERP environment.

Common ETL tools used in ERP projects include Informatica PowerCenter, Talend, Microsoft SQL Server Integration Services (SSIS), IBM DataStage, and Oracle Data Integrator. These tools provide connectors to ERP systems, graphical design interfaces, data quality features, scheduling and orchestration, and metadata management, all of which help automate data integration, enforce transformation logic, and monitor pipelines.
