Define Information
 What do individuals/businesses
do with the data they collect?
– They turn it into “information”
– “Information is the intelligence and
knowledge derived from data”
 Businesses analyze raw data in
order to identify meaningful trends
– For example:
 Buying habits and patterns of
customers
 Health history of patients

Value of Information to a Business
 Identifying new business opportunities
– Buying/spending patterns
 Internet stores, retail stores, supermarkets
– Customer satisfaction/service
 Tracking shipments, and deliveries
 Identifying patterns that lead to changes in existing business
– Reduced cost
 Just-in-time inventory, eliminating over-stocking of products, optimizing shipment
and delivery
– New services
 Security alerts for “stolen” credit card purchases
– Targeted marketing campaigns

Storage
 Data created by individuals/businesses must be stored
for further processing
 Type of storage used is based on the type of data and the
rate at which it is created and used
 Examples:
– Individuals: Digital camera, Cell phone, DVD’s, Hard disk
– Businesses: Hard disk, external disk arrays, tape library
 Storage model: An evolution
– Centralized: mainframe computers
– Decentralized: Client –server model
– Centralized: Storage Networking
