On the surface many-to-many in EF6 and EF Core look very similar.

However, under the covers the design in EF Core 5.0 provides  more flexibility and power.

In this episode, Arthur Vickers returns to chat some more with Jeremy about some of the new  features in Entity Framework Core 5. In particular, they’ll be diving deep into the building blocks of many-to-many. You’ll see how they can be configured to allow flexible mapping and access to the underlying join table.

It’s very easy to be distracted by the latest and greatest approaches with technology, but sometimes there’s a reason old approaches stand the test of time.

Star Schemas & Kimball is one of those things that isn’t going anywhere, but as we move towards the “Data Lakehouse” paradigm – how appropriate is this modelling technique, and how can we harness the Delta Engine & Spark 3.0 to maximize it’s performance?

This session looks through the historical problems of attempting to build star-schemas in a lake and steps through a series of technical examples using features such as Delta file formats, Dynamic Partition Pruning and Adaptive Query Execution to tackle these problems.
