Implement a single task within the job that sequentially reads data from all sources, performs all transformations in one go, and then loads the results into the data warehouse.

Design a multi-task job where each task is dedicated to reading data from a specific source, performing the necessary transformations, and then passing the processed data to the next task in sequence.

Create a multi-task job with each task independently reading from a specific source, performing transformations, and writing the results to a separate data warehouse, without any task dependencies.

Structure a multi-task job with a task for each data source, where each task writes the transformed data to a common data warehouse, and configure the tasks to run in parallel where possible to optimize performance.
