As data professionals, mastering the skill of designing and building semantic models is crucial, especially when preparing for the DP-600 exam. In this 3rd article I tried to write an insightful guide focusing on this exact topic, emphasizing best practices for creating efficient semantic models using Microsoft Power BI.
The guide delves into the importance of semantic models, which are structured frameworks that help define relationships and hierarchies within data, making it more accessible for interactive analysis and reporting. It outlines a step-by-step process, starting from creating a new report in Power BI Desktop to loading data and defining relationships between tables.
Understanding the differences between snowflake and star schemas is also highlighted, with a preference for the star schema due to its simplicity and performance benefits. The guide further explains normalization and denormalization processes, crucial for transforming complex data structures into more efficient models.
For anyone looking to enhance their data modeling skills and prepare for the DP-600 exam, this guide is an invaluable resource.
