Ask Dan! What are the advantages and disadvantages of Data Warehouses?

Companies are implementing data warehouses for 2 major reasons: 1) 
managers want more information to support their decision-making and 2) 
competitors are implementing data warehouses and that has a "snowball" 
effect that encourages other companies to implement data warehouses.

I think the primary motivation for investing in data warehouses is to 
provide more timely information for decision-making.  Some managers 
claim the purpose is to serve current customers better, but managers 
aren't always clear about how that will happen.  The growth of the 
Business Intelligence/OLAP software market indicates that managers need 
more than faster access to data.  Managers need analysis of data to gain 
benefits from data warehouses/data marts.
 
> 3) a. What advantages are there in developing a Data Warehouse?
The three advantages that initially come to mind are:
a. integration of data
b. new types of analyses can be performed
c. historical data becomes more accessible
In another Ask Dan! What are the benefits of a data warehouse?
I stated the benefits to putting your data into a data warehouse 
include: 
1. Merging subject specific data together to create information 
2. Standardizing data across the organization
3. Improving turnaround time for reporting
4. Lowering costs to print and distribute reports
5. Sharing data or allowing others to easily access your data 
> 3) b. What disadvantages are there in implementing a data warehouse?
The major disadvantage is that a data warehouse can be costly to 
maintain and that becomes a problem if the warehouse is underutilized.  
It seems that managers have unrealistic expectations about what they 
will get from having a data warehouse.
