Data Analysis Expressions (DAX) is the native formula and query language for Microsoft PowerPivot, Power BI Desktop and SQL Server Analysis Services (SSAS) Tabular models. DAX includes some of the functions that are used in Excel formulas with additional functions that are designed to work with relational data and perform dynamic aggregation.
Analysis Services includes a group of OLAP and data mining capabilities and comes in two flavors multidimensional and tabular, where the difference between the two is how the data is presented. [ citation needed ] In a tabular model, the information is arranged in two-dimensional tables which can thus be more readable for a human.
Smart Diff - compares versions of a SSAS, SSIS, and SSRS files. BIDS Helper pre-processes XML files so that the diff versus source control is more meaningful. Tabular Actions Editor - provides a UI for editing actions for Tabular models. For example, this feature allows the model designer the ability to customize the columns returned by ...
The snowflake schema is in the same family as the star schema logical model. In fact, the star schema is considered a special case of the snowflake schema. The snowflake schema provides some advantages over the star schema in certain situations, including: Some OLAP multidimensional database modeling tools are optimized for snowflake schemas. [3]
In addition, the Python extension allows SPSS to run any of the statistics in the free software package R. From version 14 onwards, SPSS can be driven externally by a Python or a VB.NET program using supplied "plug-ins". (From version 20 onwards, these two scripting facilities, as well as many scripts, are included on the installation media and ...
This is an attempt to model or fit an equation line or curve to the data, such that Y is a function of X. [74] [75] Necessary condition analysis (NCA) may be used when the analyst is trying to determine the extent to which independent variable X allows variable Y (e.g., "To what extent is a certain unemployment rate (X) necessary for a certain ...
Data centric test framework specialized for the Microsoft Business Intelligence platform. Tests equivalence of result sets based on SQL, MDX or DAX queries, performance, syntax, structure and dimensions' members (Multidimensional and Tabular SSAS). Includes a tests generator. NFluent [397]
In computing, the star schema or star model is the simplest style of data mart schema and is the approach most widely used to develop data warehouses and dimensional data marts. [1] The star schema consists of one or more fact tables referencing any number of dimension tables .
