Mountains of Data
Organizations have lots of data Data is not in a form that is useful to
decision-makers– Not easy to review– Not informative nor insightful

Today’s Information Flow
Business in 90’s invested in transactional systems:
– Supply Chain Management (SCM)– Customer Relationship Management (CRM)– Enterprise Resource Planning (ERP)– Manufacturing Resource Planning (MRP)– Finance (budget, forecasting and reporting)

What is BI?
The process by which an organization
manages large amounts of data, extracting pertinent information, and turning that information into knowledge upon which actions can be taken.
![Page 10: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/10.jpg)
What is BI?
Business intelligence (BI) is a broad category of application programs and technologies for gathering, storing, analyzing, and providing access to data to help enterprise users make better business decisions.
![Page 11: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/11.jpg)
BI
Involves PEOPLE and Technology Involves using a rational approach to
management Involves a continuous cycle of measurement,
adjustment & re-measurement

The Problem

GAP
How do I increase sales????
How do I make my product better???
How do I retain customers?
![Page 22: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/22.jpg)
Bridging the Gap
Need data storage structures to facilitate fast analysis of huge volumes of data
Need software to provide access to the data, allow flexible manipulation, and provide meaningful presentation
![Page 23: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/23.jpg)

Multi-Dimensional Databases
Measures– Any quantitative expression – Some are designated as Key Performance Indicators (KPI)– Appropriate to the business process.
Dimensions– How we describe the measures:
Product/Customer/Region/Time– These are the “By’s– “What were our Customer Sales by Product Line by
Region by Quarter for the past two years?”.

information needs
Analytic Applications– Allow users to visualize and explore data
following their train of thought– Extensive interactivity

Summary
Students learn to:– Create multi-dimensional databases– Create professional quality reports– Use analytics to provide in-depth data analysis
![Page 34: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/34.jpg)

Data Warehouse Topics
Decision Support Systems– history
Requirements Gathering– Where data located, owners, definition, how often
updated
Data Analysis– Determine for table structures

How is data consolidated?
This is difficult!!!!!– Data is often spread across multiple systems,
stored in different formats, and may even be localized for different countries
![Page 40: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/40.jpg)
Transforming Data
Data must be transformed for consistency and meaning
– Transformations may be as simple as copying columns or may be incredibly complex
– Common transformations include: Hard-coded changes (‘T’ to 1) Looking up values in a table (mapping a customer number
across disparate systems) Inserting dummy records and mapping them to unknowns
(inserting an ‘Unknown’ customer)
![Page 41: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/41.jpg)
Cleansing Data
Data must be cleansed to be meaningful– All companies have “bad” data in their systems– Data may be missing– Data may be inconsistent– Data may be wrong
![Page 42: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/42.jpg)
Data Warehouses
ETL (extract, transform and load) processes are needed to create data warehouses– This is an arduous and technical process that can
account for a large percentage of a BI project cost!!!!
![Page 43: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/43.jpg)
Data Mining
![Page 44: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/44.jpg)
Data Mining
The process of identifying patterns in data
Goes beyond simple querying of the database
Goes beyond multi-dimensional database queries as well
![Page 45: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/45.jpg)
Data Mining
Data Mining works for problems like:– Develop a general profile for credit card customers
…– Differentiate individuals who are poor credit risks
…– Determine what characteristics differentiate male
& female investors.
![Page 46: Focus on Business Intelligence](https://reader034.fdocuments.in/reader034/viewer/2022051819/54c6d95b4a7959ef018b4577/html5/thumbnails/46.jpg)
Data Mining vs. Data Query
Use data query if you already almost know what you are looking for.
Use data mining to find regularities in data that are not obvious.

How does Data Mining work?
Uses induction-based learning:
The process of forming general concept definitions by observing specific examples of concepts to be learned.
