Explanation
ETL (Extract, Transform, Load) systems like Informatica have three main architectural components: Designer Tool (for creating mappings and transformation logic), Workflow Manager (for creating and scheduling workflows), and Workflow Monitor (for monitoring execution and troubleshooting). All three are essential - Designer builds the data flow logic, Workflow Manager orchestrates the execution schedule, and Workflow Monitor provides runtime visibility. The question uses the standard Informatica component naming.
