Study Notes

Access and Delivery

Data warehouses hold significant information potential
Users of data warehouses need to be categorized
Different information delivery mechanisms exist
Each user type needs the correct information delivery method
The overall information delivery framework needs understanding and analysis of its components

Information from the Data Warehouse

Data warehouses make strategic information available
Source systems would be unnecessary if data were readily available
Data warehousing makes better strategic decisions possible by accessing source system data formatted for query and analysis

Data Warehouse VS Operational Systems

Data warehouses and operational systems differ in the information they contain
Usage of information differs between databases
The value of information differs between databases

Information Potential

Data warehouses are critical for overall enterprise management
Data warehouses are important for planning and assessing marketing campaigns to aid in market expansion

Information Potential for Business Areas

Data warehouses support profitability, growth, strategic marketing, customer relationship management, and corporate purchasing.

Stages in the Realization of Information Potentials

Define business requirements in terms of business rules for data warehouse use
Select appropriate data subsets aligned with business rules
Add value calculations (totals, averages) and translate codes to business terms
Relate data with business meanings using metadata
Organize data into user-friendly formats
Present data in various formats (tables, text, graphs, charts)

User-Information Interface

A solid interface is essential for data warehouse information delivery
The interface sits in the middle, facilitating information delivery to users
The interface can be a set of tools and procedures tailored for the environment
Specify necessary interface features and characteristics without getting into user details
Define the general characteristics of the user-information interface

Information Usage Modes

Data warehouse use can be categorized into verification and discovery modes

Approaches for the Interaction

Informational approach, analytical approach, and data mining approach are used for interaction with data

User-Information Characteristics

Preprocessed information, predefined queries and reports, and ad hoc constructions are characteristics of user-information

Essential Features for the User-Interface

User-friendliness
Flexibility
Versatility in presentation
Metadata linkage
Process management

Industry Applications

Sample industry sectors include manufacturing, retail and consumer goods, and banking and finance

Classes of Data Warehouses

Data warehouse users are categorized into miners, tourists, explorers, farmers, and operators
- Miners are focused on knowledge discovery
- Tourists are interested in business indicators
- Explorers focus on ad-hoc analysis
- Farmers concentrate on routine analysis
- Operators deal with current data

Classes of Users

Classify users as casual/novice, regular, and power users based on computing proficiency

Dashboard and Scorecards

Dashboards and scorecards are powerful business intelligence tools helping in optimizing performance and strategic decisions
Crucial to understand the strategic approach of the balanced scorecard (BSC) and implement it incorporating business logic

Dashboard and Scorecards (continued)

Dashboards show visual graphs and raw data
Scorecards utilize charts and progress updates
