Some data-related tasks that you want executed. SSIS packages can easily be scheduled to run frequently, it's also possible to create one-shot packages that execute a specific task just once. For example, import some sample data into a database. Even though you can create packages that do everything, it's a development best practice to create packages that have one single task.
