same results after execution.The automatic generation of statements through the visual interface helps us learn, and it's a good way to learn when it comes to problems.Iii. SummaryAt this point, we have introduced the preliminary use of the SSAS-related tools.You need to familiarize yourself with the development interface of SSDT and familiarize yourself with the commonly used MDX syntax (about MDX now you need to do a preliminary understanding, and

Original: SSAS Series--"03" Multidimensional data (Cube object)1. What is cube?A simple Cube object consists of basic information, dimensions, and measure groups. Basic information includes the name of the cube, the default measure for the cube, the data source and storage mode, and so on. Dimensions are the actual dimension groups used in the cube. All dimensions must be defined in the dimension collection

Original: SSAS Series--"02" Multidimensional Data (Dimension object)1. What is dimension? In mathematics, it is called a parameter, which is the number of independent space-time coordinates in physics. 0-Dimensional is a point, 1-dimensional is a line, 2-dimensional is a long and wide (or curved) area, 3-dimensional is 2-dimensional plus the height to form the volume surface. In physics, Time is the fourth

Original: SSAS Series-"07" Multidimensional data (query cube)1. What is MDX? MDX, called Multidimensional Expressions , is a query language, a query language similar to SQL, based on the XML for Analysis (XMLA) specification, with extensions specific to SQL Server analysis Services. 2.
