DW / BI
Concepts
Information Management Strategy
Structure the systems and data
relationships to provide user-friendly
customer access to data in order to
provide decision-making information.
Adding Value to Data
Information Pyramid
What is a Data Warehouse?
A copy of data from one or more On-line
Transaction Processing (OLTP) systems
specifically structured for Query,
Reporting and Analysis (QRA).
• Data is typically at a summarized level to limit the
size and complexity of the data warehouse
• Data is usually cleansed and merged to create an
“apples to apples” comparisons

Warehouse
Complexity
• Warehouse Complexity
• Destructive vs. Incremental Loads
• Integration (mergers/acquisitions)
– Data integration (consolidation of information)
– Process integration (consolidation of processes)
• Smaller windows of opportunity
– Make decision in a shorter period of time due to competitive,
global market
• Global marketplace (DW timing updates)
• High-profile e-Business initiatives
– Satisfying requirements
ETL - The “Heavy Lifting”
• Challenge to develop efficient, consistent
methods of gathering and cleansing
heterogeneous data
– Capture and load of data from multiple source
systems (both internal and external)
– Integrates data into a single source
– Cross-system mapping to standard identifiers
(surrogate keys)
– Aggregation for information delivery and BI
initiatives
ETL Tools - Only Half the Story
• Half the story: ETL Tools Extract, Transform, and
Load data
• Transport data between sources and targets
• Document data element changes (metadata)
• Administer run-time processes and operations

•
Initial Project meeting should include:
– Client - gives input on look and feel, data requirements, timelines
– Project Manager – ensures project is feasible within budget and time
restraints at the onset and through out the project.
– Data Warehouse Architect – ensures all the needed data is in the data
warehouse.
– Business Intelligence Specialist (cube builder) – ensures all the needed
data is in the cube, in the correct format
– Web Interface Specialist (visualization builder) – works with cube builde
and client to established look and feel, navigation, chart styles, etc..
