ERP and the Data Warehouse
• One of the most important advances in technology in the
past 10 years has been Enterprise Resources Planning
(ERP), the application and transaction processing built
for a company. The applications and transactions – built
and maintained centrally by the vendor – cover the
following corporate functions:
• Human Resources
• Inventory Management
• Financial Management

ERP and the Data Warehouse
• ERP is lead by such companies as SAP,
PeopleSoft, JD Edwards, BAAN, Oracle
Financials, and others.
• There are several reasons why organizations
find ERP application software attractive. The
primary reasons focus on the frustrations in
handling existing applications. These include the
following:
– Aging. Many organizations have applications that
were written years ago.

ERP and the Data Warehouse
– Unintegrated. Existing applications each take a
narrow view of the business. And no two applications
have the same definitions, the same calculations, the
same encoding structure, the same key structure as
any other applications. When a corporate perspective
of data is needed, there is none.
– Incomplete. Existing applications do not take into
account such important events as year 2000 and the
movement of currency to the Euro.
