Conformed Dimensions (CD): These dimensions are something 
that is built once in your model and can be reused multiple 
times with different fact tables.   

For example, consider a model containing multiple fact 
tables, representing different data marts.  Now look for a 
dimension that is common to these facts tables.  In this 
example, let us consider that the product dimension is 
common and hence can be reused by creating short cuts and 
joining the different fact tables. Some of the examples are 
time dimension, customer dimensions, product dimension.

Confirm dimension;

Confirm Dimension which is used to link more then 0ne fact 
table or data mart.
 
For ex;
In our project, we have created five data mart of different 
subject area ,our client requirements is to create a report 
by linking all the data mart or subject area .To achieve 
that report we linked all the data mart through  Person 
confirmed dimension .

A confirmed Dimension (CD) is a dimension which is shared by
different fact tables.

For examples, there are different data marts are there say
Loans, Deposits, Withdrawals etc.....in this there is a
dimension called Date which is common to all. We can link to
different datamarts using a common dimension called Date in
this example.

Confirmed Dimension, it is a dimension linked with two fact
tables.

Confirmed Dim means a dimensions which is connected with
the two fact tables 
suppose we have two fact tables like sales and production
link with dimension product dimension here Product is the
confirmed  dimesion

A dimension that carries the same meaning across the
different fact tables is called conformed dimension
conformed dimension are a must to put a no of datamarts
together to create a enterprise datawarehouse

In the schema which dimension shared by multiple fact table 
that dimension is called confirmed dimension.

Confirm dimension is a dimension which is connected with 
more than one fact table.We can say date dimension is the 
confirm dimension.

if aprimary key act as a fk in more then fact tablethen it 
is known as cd
