Recently I published an open-source course/workshop to learn Power BI Desktop. Fellow MVP Dan English (blog | twitter) gave me the excellent feedback that IMDB actually doesn’t like people scraping their website for data. Furthermore, the OMDB API appears to have fallen almost out of funds and is thus not as reliable as I thought. Refreshing the queries takes an incredibly long time (previously around 2 minutes, but now I cancelled after 10 minutes), which makes the .pbix unworkable for teaching Power Query.
Instead of writing a function in Power Query, the exercise now focuses more on merging queries (which is perhaps a better exercise for starting users).
- Changed source data to two files: Excel file for the top movies and flat file for extra movie information
- Updated the exercises to reflect the changes in Power Query
- Deleted two columns in the model, since they were actually duplicates of other columns.
- Removed all references to IMDB, since we’re not using their website anymore
- Added a slicer at the report “New Features 2” to demonstrate that the time slicer can be affected by other slicers. You have to set the interactions to filter though.
- Changed some screenshots in the slidedeck
