A fact tablefact tableIn data warehousing, a fact table consists of the measurements, metrics or facts of a business process. It is located at the center of a star schema or a snowflake schema surrounded by dimension tables. Where multiple fact tables are used, these are arranged as a fact constellation schema.

## What is facts and dimension with example?

Employees and customers are examples of dimensions, they do. Products are sold, they are also dimensions as they have something done to them. Facts, are the verb. An entry in a fact table marks a discrete event that happens to something from the dimension table.

## What is the relationship between fact and dimension?

The answer is one-to-many. A star schema has one-to-many type of relationship from a dimension to a fact table. One or more fact tables refer ‘n’ number of dimension tables.

## How can you tell the difference between a fact and dimension table?

The main difference between fact table or reality table and the Dimension table is that dimension table contains attributes on that measures are taken actually table. 1. Fact table contains the measuring on the attributes of a dimension table.

## Is date a fact or dimension?

Typically dimensions in a data warehouse are organized internally into one or more hierarchies. “Date” is a common dimension, with several possible hierarchies: “Days (are grouped into) Months (which are grouped into) Years”, “Days (are grouped into) Weeks (which are grouped into) Years”

## What are facts measures and dimensions?

A measure is a numerical property of a fact that describes a quantitative attribute that is relevant to analysis. For example, each sale is measured by the number of units sold, the unit price, and the total receipts. A dimension is a property, with a finite domain, that describes an analysis coordinate of the fact.

## What is fact table with example?

A fact table is found at the center of a star schema or snowflake schema surrounded by dimension tables. A fact table consists of facts of a particular business process e.g., sales revenue by month by product. Facts are also known as measurements or metrics. A fact table record captures a measurement or a metric.

## What is content dimension?

Content dimensions is a generic concept to have multiple variants of a content node. A content dimension can be anything, but the most widely known use case for a content dimension is a translation for a different language or country. The content repository supports any number of dimensions.

## What is star schema in database?

A star schema is a database organizational structure optimized for use in a data warehouse or business intelligence that uses a single large fact table to store transactional or measured data, and one or more smaller dimensional tables that store attributes about the data.

## Is customer a fact or dimension?

For most subject areas, it’s pretty easy to identify the major dimensions: Product, Customer Account, Student, Employee, and Organization are all easily understood as descriptive dimensions.

## Is a customer ID a fact or a dimension?

Thats pretty much it. If you had a list of sales orders as a fact. Each row or fact may have a customer ID, a Sales Rep ID, a product ID etc.. And then you would have 3 dimension tables.

## How many types of dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time.

## Is gravity a dimension?

Gravity is a force it is not a dimension. If these models of quantum gravity is correct then we do live in these 10 dimension. If these models are correct then we do live in “hyperspace”, but only 3 dimensions are macroscopic. Dimensions don’t govern the laws of physics.

## What are the different types of facts?

We can divide the Facts in to these three types.

## Is time a dimension?

According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension.

## Are humans 4 dimensional?

We are actually four dimensional. We are comprised of 4 distinct but integrated parts. Three of which are related to our physical experience – the body, heart and mind. The fourth is the dimension of consciousness or spirit.

## In what dimension does God live?

Originally Answered: If God exists, in which dimension is he? In the 10th dimension, all possibilities are contained. Super strings that vibrate in the 10th dimension are what create the subatomic particles which make up our universe and all other possible universes. It is here where God resides.

## What dimension are we living in?

three dimensions

In everyday life, we inhabit a space of three dimensions – a vast ‘cupboard’ with height, width and depth, well known for centuries. Less obviously, we can consider time as an additional, fourth dimension, as Einstein famously revealed.

## Is real life 3D or 4D?

We live in a 3D (D stands for dimensional) world with the 4th dimension as time.

## Can life exist in 4 dimensions?

In recent decades, physicists have explored this question by investigating the properties of other universes to see whether complex life could exist in them. Their conclusion is that it could not exist in a universe with four dimensions, nor in one with more than one dimension of time.

## Do humans see in 3D or 4D?

We are 3D creatures, living in a 3D world but our eyes can show us only two dimensions. The depth that we all think we can see is merely a trick that our brains have learned; a byproduct of evolution putting our eyes on the front of our faces. To prove this, close one eye and try to play tennis.

## What if we had 4 eyes?

Quote from video: What if we had four eyes even i have four eyes i can see everything. Oh i'm some firstly. If we had four eyes average players might now become great in sports.

## Can eyes see 4D?

You would need six eyes to see in 4-D. The reason for this is that our point of view is one dimension less than our current dimension. Therefore, to see in 4-D, you need to have a spherical view and maybe even spheric tesseract shaped eyes. (A tesseract is one dimension higher than a cube.)
