The SSAS Date dimension is basically present in all Cube design processes, and it is difficult to see an OLAP database with no time dimension. However, depending on the project requirements, the Date dimension may be designed differently, so there are a few issues to be aware of when designing the Time dimension: What is the minimum level of detail involved in your business?

In addition to the time dimensions that appear in previous articles, there is a special dimension-parent-child dimension in addition to the design of the snowflake dimension. A parent-child dimension is special in that it contains a reference structure based on a recursive relationship (recursive relationship), and in my article I mentioned how to design and make a SSRS report based on a parent-child hierarchy, but that report is based on the Data warehouse. Now we want to design a SSRS based on

This article will introduce the use of Analysis Services SSAS how to solve the ratio, year-on-year and chain three indicators. First, understand the basic concepts of these three indicators: Jambi refers to the ratio of the current member's value to that of the member's parent, meaning the proportion of the total, such as a fruit store total sales of 14, of which Apple's sales are 2, accounting for 14.3%. Year-on-year is the value in a period compared
