Introduction
As
we all know that the Time Dimension is a special type of Dimension and almost
all multi-dimensional models have the Time Dimension exist. Here we are not
going to describe about the Time Dimension in details as we assume that the
purpose of it has known by all.
Here
in this article we are going to describe about some important property of Time
Dimension that makes a normal Dimension to Time Dimension and how to use
Business Intelligence to set those Property.
How we Create a Time Dimension
There
is two options to create time dimension, by using Existing Table or Generating
Time Dimension.
If
we choose the Option -2 SSAS take care of all and nothing to worry.
But
if we chose the Option-2 means By Using Existing table we have to set something
for that others it teat as Normal Dimension.
Two
understand it lets take an example.
Create Time Dimension using Existing Table
We
have an existing table
SELECT * FROM [dbo].[DIMTime1];
Sample:
PK_Date Date_Name Year Year_Name

When
we create a Time Dimension from the existing table
The
Dimension property named Type is
showing Regular and it need to be
change first.
Dimension Property
Type = Time
Now
it is treated as Time Dimension.
What Next ?
Now
we are going to add all the attributes and choosing some attributes we are
going make hierarchy of Time Dimension. Named it as Calendar-Hierarchy
If
we look at the Calendar-Hierarchy, we find that there is a warning message comes
and saying
Attribute relationship
does not exists in one or more level of hierarchy. They may result of degrade of
performance …etc.
This
can be fixing by using attribute relationship (Natural- Hierarchy).
Now it’s Time to Add Business Intelligence
