Datamonster Essential - Python for Data Engineering

Intended Audience: Citizen Data Engineer, BI Developers, Data Analysts, Analytics Engineers

Level: 200-300 (Intermediate)

Low Code Data transformation, Data modeling, Data analysis, SQL

Duration: 9:00 – 17:00 (including 60min lunch and 2*15min coffee break)

Trainer: Tom Martens (Microsoft Data Platform MVP, Speaker, Book Author, Datamonster)

Prerequisites (some are softer, one is hard):

· Basic understanding of data modeling (star schema or dimensional modeling)

· Ability to access your Fabric-enabled workspace in your Power BI/Fabric tenant to create and query Fabric items like lakehouses, delta parquet tables, and semantic models from your laptop. The Fabric-enabled workspace can either reside inside a corporate Fabric or private tenant.

· If you do not have access to your own Fabric-enabled workspace, this will be provided by datamonster e.V.

· Bring your own laptop (no special programs are required), WIFI access is a must

· First experience with programming languages like R or Python (helpful but not required)

Course Outcome:

· Create and Execute notebooks inside Microsoft Fabric

· Use Python to transform and shape data

· Use Python to write to and read from delta tables

· Use Python to move data to the various stages of a lakehouse

· Understand the benefits of a medallion architecture

Abstract

This course introduces tackling data engineering tasks using Python and notebooks within Microsoft Fabric. In addition to an introduction to Python, modern lakehouse architecture is explained. You’ll be introduced to the skills necessary to succeed as a data engineer and how to apply these skills practically using Microsoft Fabric!

This course includes practical examples that any Citizen Data Engineer can immediately apply in their day-to-day job and many valuable tips related explicitly to tackling typical data engineering tasks.

Even though Microsoft Fabric is used during the course, using Python for data engineering with Spark can be combined with many other platforms that harness the power of Spark.
