Composite Models via DirectQuery over Power BI Datasets

Paul Turley is living the dream:

Last year I wrote this post about the new composite model feature in Power BI that enables datasets to be chained together using a featured called “DirectQuery for PBI Datasets and AS“. The prospect of creating a data model that virtually layers existing data models together without having to repeat the design, sounds like nothing less than Utopia. We can leverage existing datasets, with no duplicate models, no duplication of business logic, and no duplication of effort. The promise of this capability is that data models may be referenced from other data models without duplicating data. So, is this really possible?

Read on for Paul’s thoughts and how they’ve changed over the past couple of months with new updates.
