This diagram illustrates a list of logical tables in the semantic model. The names of all the dimension tables are prefixed D so they're grouped together in the list. For example, Dim0 - Time, Dim1 Products (Level Based Hierarchy), Dim2 Products (Ragged SkipLevels Hier), and so on. Similarly, the names of all the fact tables are prefixed F and are grouped together. For example, F0 Sale Base Measures, Fact2 Fragmented Measures Targets, F3 Quota Based Measures, and so on.
