What does "reusability" refer to in DTS packages?

Reusability in the context of DTS (Data Transformation Services) packages specifically refers to the ability to create components that can be utilized across different packages. This capability is essential for efficient development and maintenance of DTS packages, as it allows developers to design components such as tasks, connections, and workflows once and then leverage them throughout various packages rather than recreating them each time.

This approach not only saves time and effort but also ensures consistency and reduces the risk of errors, since common elements are refined in one location and reused as needed. Using reusable components leads to easier updates and modifications across multiple packages when changes are required.

In contrast, the other options focus on different functionalities that do not align with the principle of reusability. For example, using multiple databases or integrating with other applications addresses operational aspects rather than the structural reuse of components themselves. Meanwhile, scheduling packages pertains to timing and execution rather than the design and development aspect emphasized by reusability.
