2/18/2023 0 Comments Table of contextsThe interaction of row contexts and relationships is very easy to understand, because there is nothing to understand: they do not interact in any way, at least not automatically. Now that we have defined the model, let’s start looking at how the contexts behave by looking at some DAX formulas. All remaining relationships are set to be one-way cross-filter direction. The only bidirectional relationship is the one between Sales and Product.There is a chain of one-to-many relationships starting from Sales and reaching Product Category, through Product and Product Subcategory.There are a couple of things to note about this model: In order to examine the scenario, we use a data model containing six tables, which you can see in Figure 4-13.įIGURE 4-13 Here you can see the data model used to learn interaction between contexts and relationships. As you are going to learn, there are some subtle interactions between contexts and relationships and learning them requires some patience. If you create a row context on a table on the many side of the relationship, do you expect it to let you use columns of the one side? Moreover, if you create a row context on the one side of the relationship, do you expect to be able to access columns from the table on the many side? In addition, what about the filter context? Do you expect to put a filter on the many table and see it propagated to the table on the one side? Any answer could be the correct one, but we are interested in learning how DAX behaves in these situations, that is, understand how the DAX language defines propagation of contexts through relationships. Finally, to make things a bit harder, please recall that relationships can be unidirectional or bidirectional, depending on how you defined the cross-filter direction on relationship itself. Thus, an interesting question is “ How do the two contexts behave regarding relationships?” Moreover, because relationships have a direction, we need to understand what happens on the one and on the many side of a relationship. It is most likely that in your data model you will have many tables linked by relationships. Very few data models contain just one single table. With only one table, you need to face only interactions between row context and filter context in the same expression. You might have noticed that we deliberately used only one table: Product. Else, you can include them in your table of contents.We just started learning contexts, and this led us to some interesting (and surprising) results up to now. If there are more than three tables and figures, you might consider listing them on a separate page. Including these two, however, depend largely on how many there are in your document. Other things to include in your table of contents include the appendices and tables. Keep in mind that the reader will see the table of contents first before reading through your document. NOTE: Ensure that you use clear headings throughout your document to make your table of contents easy to understand. Level Three: 2.1.1 Discipline of Knowledge Here is an example of the different heading levels You may also decide to include level three headings, although they are optional to include and should not be included in the TOC has reached its maximum length of two pages. When creating your table of contents, make sure to include all level one and two headings. The page numbers that show where in the document each section can be found.The key elements that should be included in the table of contents are: A clear and well-out table of content is very important as it indicates a quality paper is structured. The table of contents is where one lists the chapters and major sections of their document, together with their page numbers.
