Introduction
In statistics and related fields, multidimensional analysis is a data analysis process that groups
data into two or more categories: data dimensions and measurements. To show this, let us take
the case of a football game. A data set which comprises of the number of wins for one cricket
team every year for many years could be categorized into a single dimensional or longitudinal
data set. Another data set which comprises of the number of wins many different cricket groups
inside a year can be under a single dimensional or traverse sectional data set. A single data set
that comprises of the number of wins for diverse cricket teams over numerous years could be
comprised in a two-dimensional data set.
Multi-Dimensional analysis is an Informational analysis on data which takes into account
numerous distinct connections, each of which comprises a dimension. For example, a retail
analyst may want to understand the connections amidst sales by district, by quarter, by
demographic circulation or by product. Multi-dimensional analysis will yield outcomes for
these complex relationships.
2.1 Dimension Attributes
