## What is cube Dimension measure?

1. Cube Structure. Measures: A measure represents **a column that contains quantifiable data, usually numeric, that can be aggregated. Dimensions: All dimension added in Dimension folder can be used in instance of a Cube. Attributes that are added and processed at Dimension level are showed in Cube Dimension.**

## What are measure groups?

A measure is an aggregation of numeric data values, such as sum, count, minimum, maximum, average, or a custom MDX expression that you create. A measure group is **a container for one or more measures. All measures exist in a measure group, even if there is only one measure.**

## What is database dimension and cube dimension?

A Database Dimension is **a Dimension which exists independent of a Cube. You can see a Database Dimension as a separate entity/file in the Solution Explorer/Project Folder. A Cube Dimension is an Instance of a Database Dimension.**

## What are cubes and dimensions in TM1?

In TM1 there are objects to hold data. These objects are called cubes. Dimensions in **TM1 are basic building blocks of cube. So if you have an excel file which captures the grocery products’ data for different months you’ll create one cube in TM1 to keep this data.**

## What is a cube dimension?

A cube is **3- dimensional shape with 6 equal sides, 6 faces, and 6 vertices in geometry. Each face of a cube is a square. In 3 dimension, the cube’s sides are; the length, width, and height.**

## What is a dimension measure?

A Database Dimension is **a Dimension which exists independent of a Cube. You can see a Database Dimension as a separate entity/file in the Solution Explorer/Project Folder. A Cube Dimension is an Instance of a Database Dimension.**

## What is difference between dimension and cube?

Dimensional measurement is **how we know and quantify the size and shape of things. It involves lengths and angles as well as geometrical properties such as flatness and straightness. Dimensional measurement is of fundamental importance for interchangeability and global trade.**

## How do you create a measure group?

In a data warehouse, a measure is **a property on which calculations (e.g., sum, count, average, minimum, maximum) can be made.**

## What is a measure in database?

To create a new measure group in SSAS, Within the Measures pane, **right-click on the cube name will open the context menu for creating Measures. From the above context menu, we have two options, such as New Measure and New Measure Group.**

## How do I create a measure group in SSAS?

A measure is **an aggregation of numeric data values, such as sum, count, minimum, maximum, average, or a custom MDX expression that you create. A measure group is a container for one or more measures. All measures exist in a measure group, even if there is only one measure.**

## What is cube dimension?

A cube dimension is **an instance of a database dimension within a cube. A database dimension can be used in multiple cubes, and multiple cube dimensions can be based on a single database dimension. The following table describes the properties of a cube dimension.**

## What are database dimensions?

A database dimension is **a collection of related objects, called attributes, which can be used to provide information about fact data in one or more cubes. For example, typical attributes in a product dimension might be product name, product category, product line, product size, and product price.**

## What is dimension in OLAP cube?

A Dimension is a structural attribute of a Cube that is **a list of related namesknown as Membersall of which belong to a similar category in the user’s perception of a data. For example, months and quarters may make up a Months dimension; likewise all cities, regions and countries may make up a Region dimension.**

## How many dimensions does a data cube have?

three-dimensional

## What is a cube in TM1?

TM1 cubes exist within the IBM Cognos TM1 solution. A TM1 cube is **a multidimensional database that must contain at least 2 dimensions and 1 fact. The data is loaded into the cube making use of a turbo integrator process. Each cube can be expanded to view all the dimensions that make up the cube.**

## What are dimensions in TM1?

An IBM Cognos TM1 server contains cubes, which, in turn are defined by one or more dimensions. A dimension is a list of related items, called elements, which you would find listed down the rows, or across the columns of a report. Cubes are the main repository of data in an IBM Cognos TM1 server.

## What are cubes and dimensions?

**Cubes contain all the dimensions on which users base their analyses of fact data. An instance of a database dimension in a cube is called a cube dimension and relates to one or more measure groups in the cube. A database dimension can be used multiple times in a cube.**

## What order are cube dimensions?

We generally recommend that you order the dimensions as follows: **smallest sparse to largest sparse, followed by smallest dense to largest dense. However, some flexibility is required.**

## What is a cube in dimensional modeling?

A cube is **a multidimensional structure that contains information for analytical purposes; the main constituents of a cube are dimensions and measures. Dimensions define the structure of the cube that you use to slice and dice over, and measures provide aggregated numerical values of interest to the end user.**

## What is a dimension or measure?

Dimensions contain **qualitative values (such as names, dates, or geographical data). You can use dimensions to categorize, segment, and reveal the details in your data. Dimensions affect the level of detail in the view. Measures contain numeric, quantitative values that you can measure. Measures can be aggregated.**

## What dimensions do we measure?

**Length, width, and height are measurements that allow us to indicate the volume of geometric bodies. The length (20 cm) and the width (10 cm) correspond to the horizontal dimension. On the other hand, the height (15 cm) refers to the vertical dimension.**

## What are facts dimensions and measures?

A fact is represented by **a box that displays the fact name along with the measure names. Small circles represent the dimensions, which are linked to the fact by straight lines (see Figure 1). A dimensional attribute is a property, with a finite domain, of a dimension.**

## What is a dimension and measure in tableau?

According to Tableau’s Knowledge Base, a dimension is a field that can be considered an independent variable. By default, Tableau treats any field containing qualitative, categorical information as a dimension. Generally, **the measure is the number; the dimension is what you slice and dice the number by**

## What is dimension and cube?

A database dimension is a **collection of related objects, called attributes, which can be used to provide information about fact data in one or more cubes ****An instance of a database dimension in a cube is called a cube dimension and relates to one or more measure groups in the cube.**

## What are differences between dimension and cube metadata?

SSAS dimensions are groups of attributes based on columns from tables or views in a data source view. A dimension that exists **independent of a cube is called a database dimension and an instance of a database dimension within a cube is called a cube dimension.**
