A dimension table or dimension entity is a table or entity in a star, snowflake, or starflake schema that stores details about the facts. For example, a Time dimension table stores the various aspects of time such as year, quarter, month, and day..
What do you mean by dimension of data?
Dimensionality is the number of columns of data which is basically the attributes of data like name, age, sex and so on. While classification or clustering the data, we need to decide what all dimensionalities/columns we want to use to get meaning information..
What do you mean dimension?
1. : the length, width, height, or depth of something : a measurement in one direction (such as the distance from the ceiling to the floor in a room) She carefully measured each dimension of the room. The room's dimensions [=its length, width, and height] were surprisingly small..
What is a dimensional model in data warehousing?
The data model used to store data in the denormalized form is called Dimensional Modeling. It is the technique of storing data in a Data Warehouse in such a way that enables fast query performance and easy access to its business users..
What is dimension data?
Dimension Data is a company specialising in information technology services. Based in Johannesburg, South Africa, the company maintains operations on every inhabited continent. Dimension Data focuses on services including IT consulting, technical and support services, and managed services..
Dimensions in SQL Server Analysis Services contain attributes that correspond to columns in dimension tables. These attributes appear as attribute hierarchies and can be organized into user-defined hierarchies, or can be defined as parent-child hierarchies based on columns in the underlying dimension table.
There are three dimensions in math; length, width, and height. Length is like measuring a piece of string: there is only one way to measure it. You can only measure it from one end to the other. A straight line on a piece of paper is another example of length.
A dimension is a structure that categorizes facts and measures in order to enable users to answer business questions. Commonly used dimensions are people, products, place and time. (Note: People and time sometimes are not modeled as dimensions.) A dimension table in an OLAP cube with a star schema.
In a data warehouse, dimensions provide structured labeling information to otherwise unordered numeric measures. The dimension is a data set composed of individual, non-overlapping data elements. The primary functions of dimensions are threefold: to provide filtering, grouping and labelling.

What is multidimensional data model in data warehouse?
Multidimensional data model in data warehouse is a model which represents data in the form of data cubes
It allows to model and view the data in multiple dimensions and it is defined by dimensions and facts
Multidimensional data model is generally categorized around a central theme and represented by a fact table
In a data warehouse, dimensions provide structured labeling information to otherwise unordered numeric measures. The dimension is a data set composed of individual, non-overlapping data elements. The primary functions of dimensions are threefold: to provide filtering, grouping and labelling. These functions are often described as "slice and dice".
A dimensional model in data warehouse is designed to read, summarize, analyze numeric information like values, balances, counts, weights, etc. in a data warehouse. In contrast, relation models are optimized for addition, updating and deletion of data in a real-time Online Transaction System.
