What interface is primarily used to create and manage DTS packages?

The primary interface used to create and manage DTS (Data Transformation Services) packages is the DTS Designer. This tool provides a graphical user interface that allows users to visually design data transformation workflows, including the steps for extracting, transforming, and loading data. Through DTS Designer, users can create various tasks, configure connections to data sources, and define the workflow for their packages. It is specifically designed for these purposes and offers features to streamline the development and management of data integration tasks.

The other interfaces mentioned serve different roles within the DTS framework. The DTS Console is typically used for executing packages rather than designing them. The DTS Scheduler is responsible for scheduling and automating the execution of DTS packages, while the DTS Monitor facilitates monitoring the status and progress of running packages. These functionalities are essential, but they do not provide the design capabilities that the DTS Designer offers.
