Time for action – loading dimensions for the sales datamart

In this tutorial, you will load each dimension for the sales datamart and enclose them into a single job. Before starting, check the following things:

• Check that the database engine is up and that both the js and the js_dw databases are accessible from PDI.

• If your time dimension table, lk_time, has data, truncate the table. You may do it by using the Truncate table [lk_time] option in the database explorer.

Tip

You may reuse the js_dw database in which you have been loading data in previous chapters. There is no problem with that. However, creating a whole new database is preferred so that you can see how the entire process works.

The explanation will be focused on the general process. For details of creating a transformation that loads a particular type of dimension, please refer to Chapter 9. You can also download the full material for this chapter where the transformations and jobs are ready to browse and try.
