At the end of March, we released the second update of SQLBI+ with a new session about different types of many-to-many relationships in DAX. The goal is to explain the difference between the many-to-many cardinality relationship available in Power BI… Read more

The composite models in Power BI introduced a new type of relationship cardinality called many-to-many. Nevertheless, despite their name, they are not many-to-many relationships: they are relationships between tables generated at different granularity. In this session, we clarify the purpose… Watch now

One of the first models I created for the many-to-many revolution white paper was the Survey one. At the time, it was in Analysis Services Multidimensional, and then we implemented it in Analysis Services Tabular and in Power Pivot, using the DAX language. Read more

We are still in the early days of DAX and even if I have been using it since 2 years ago, there is still a lot to learn on that. One of the topics that historically interests me (and many of the readers here, probably) is the many-to-many relationships Read more

In September 2006 I had announced in this blog the release of the first version of The Many-to-Many Revolution, a whitepaper that describes how to leverage the many-to-many dimension relationships feature that had being available since Analysis Services Read more

Thanks to a comment sent by a reader of my M2M paper , I just found a possible bug (or " not supported by design feature") of the CREATE LOCAL CUBE mdx statement. In short, it seems that a simple many-to-many dimension relationship is supported, but if Read more

More than one year ago I published a paper about design patterns for many-to-many dimension relationships . Since then, I built other models and I got more experience about possible performance optimizations. Unfortunately, I still hadn't time to write Read more

SQL Server 2005 has a new version of Analysis Services with a lot of new features, so much that a whole (thick) book would be necessary to describe everything. Nevertheless, many improvements are "marginal", in the sense that bring us better productivity Read more
