Time for action – loading the dimensions for the sales datamart
In this section, 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_dwdatabases are accessible from PDI.
- If your time dimension table
lk_timehas data, truncate the table. Remember that you can do it by right-clicking on the table in the database explorer and selecting the Truncate Table option.
You may reuse the
js_dwdatabase in which you have been loading data in previous chapters. There is no problem with that. However, dropping the database and creating the tables again is preferred so that you can see how the entire process works. ...
