as Interim Integrators
• The reasons for The Split of Operational
and Information Database
• Benefit of Warehouses
• Managing The Architecture
• There You Have IT!
3
Warehouse and Decision Support System as
Interim Integrators
Data warehouse is a database that provides
users with data, extracted from production
and online transaction processing system,
that supports analysis activities.
4
Warehouse and Decision Support System as
Interim Integrators
The source of data for data warehouse is
the operational architecture.
5
Warehouse and Decision Support System as
Interim Integrators
The data in operational types of database is
structured for transaction processing, not
for data search and retrieval.
6
Warehouse and Decision Support System as
Interim Integrators
A decision support architecture is made up
of a set of data warehouse and software
tools that analyze data held in warehouse.
7
Warehouse and Decision Support System as
Interim Integrators
Operational database, online analytical
processing (OLAP) is software
characteristic used in the decision support
environment against data warehouse.
8
The reasons for The Split of Operational and
Information Database
• The data serving operational needs are
physically different data from those serving
information or analytical needs.
• The supporting technology for operational
processing is fundamentally different from the
technology used to support informational or
analytical needs.
• The user community of operational data is
different from the one served by informational or
analytical data.
• The processing characteristics for the
operational environment and the informational
environment are fundamentally different.

Benefit of Warehouses
 To meet the needs of management. The
information in the warehouse allows managers
to make better decisions.
 Raises the visibility of significant problems in
the operational architecture.
 Buffer you from some of data quality and
compatibility
problems
in
the
legacy
operational architecture.
 Create data model without considering the
legacy environment. (this is a good place to
create the enterprise data model and identify
data standards.)
10
Managing The Architecture
• Requires some sort of central control.
• Places the definition and management of
the business views of the architecture
centrally.
• Allows central authority with centralized
deployment, a true balance of power in
enterprise.
11
There You Have IT!
• Designing and implementing a streamlined,
integrated information architecture is not so
difficult.
• First, define systems boundaries based on
classification theory so that each information
system has the fewest possible tentacles into
other information system.
• Then, design a technology architecture that links
these information systems using hubs to
minimize the number of links even further.
