6. ISDMR :BEIT VIII:CHAP1 MADHU N 6 What is Data Data is converted into more convenient form i.e. Digital Data –Increase in data processing capabilities –Lower cost of digital storage –Affordable and faster communication technology Who creates data? –Individuals –Businesses “Collection of raw facts from which conclusions may be drawn” 01010101010 10101011010 00010101011 01010101010 10101010101 01010101010 Video Photo Book Letter Digital Data

7. ISDMR :BEIT VIII:CHAP1 MADHU N 7 Categories of Data Data can be categorized as either structured or unstructured data Over 80% of enterprise information is unstructured Rows and Columns Contracts Images Manuals X-Rays Instant Messages Forms E-Mail Attachments Check Documents PDFs Web Pages Audio Video Invoices Rich Media Structured (20%) Unstructured (80%)

8. ISDMR :BEIT VIII:CHAP1 MADHU N 8 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 Users of Information Centralized information storage and processing Uploading information Accessing information WiredWirelessWiredWireless Network Demand for more Information Creators of information Virtuous cycle of information

9. ISDMR :BEIT VIII:CHAP1 MADHU N 9 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 Communicate to bank customers with high account balances about a special savings plan Creating a competitive advantage

10. ISDMR :BEIT VIII:CHAP1 MADHU N 10 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
