Hi,

For me I started from a SQL base but I really think it depends what background your coming from. If you are used to using Python day in day out then use that, if you've used SQL then use SQL first. Next I'd say understand declarative pipelines and lakeflow connect. Have a play and build out an end to end ingestion pipeline. This will also help you to think about medalion architecture and what you should do at each step in the architecture. Think about the use cases for materialized views vs streaming tables.
Next up, build a dashboard and a genie room. Finally, start experimenting with the AI functionality, it's good to put some PDFs into a volume and build a simple knowledge assistant you can then pair this up with your Genie room and work out which is best for what. 

At this point you'll start to understand the breadth of the Databricks platform, then you can start to focus in on one area.

Thanks,

Emma
