Combining the execution of jobs and transformations

In real projects, you don't run isolated transformations or jobs. Instead, you combine their execution, in order to create a flow of tasks. In particular, you can run jobs or transformations from a job, and you can also iterate the execution of transformations and jobs by simulating a loop. In this section, you will learn how to implement some of these combinations. The sample jobs and transformations will be related to the datamart introduced in Chapter 5, Loading Data.

Executing transformations from a job

To demonstrate how to execute a transformation from a job, we will create a job with the following purpose: it will find out the maximum date in the injuries fact table, and then it will load the fact table by using that date to filter the data to insert.

Note

Before continuing, make sure that you delete the data inserted in the previous chapter from the Injuries fact table. This will allow you to follow the next exercises exactly as they...
