New terminologies

The new generation of composite models comes with new terminologies. Understanding these terms helps us to resolve more complex scenarios more efficiently and with fewer issues. In the following few subsections, we will learn about these new terms.

Chaining

Chaining is a new terminology introduced with the new composite model. When a Power BI report or dataset is based on some other semantic model hosted in SSAS tabular, AAS, or Power BI datasets, we create a chain; in other words, chaining is about the dependencies between semantic layers used in composite models. So, when we create a dataset on top of other datasets, the new dataset depends on a series of other datasets.

Chain length

When we create a chain, its length refers to the number of semantic layers the current dataset depends on. Let’s implement a scenario to understand these terminologies better.

The business has a semantic model hosted in an AAS dataset that is still under...
