Information in the form of: • Email• web pages• reports• memos and handouts• lectures• telephone calls• meetings and tutorials
Example :1. University / College :
- information about students, departments, tutorial groups, faculties, lecturers, computer labs
2. Business Organisation - information about stakeholders, government policies, recruitment, profit and loss, training, etc
3. Hospital- information about medicines, doctors, nurses, laboratories, outpatients, wards, ambulance, etc
Primary purpose of IS is Information. Information Flows in Organisations

Data vs Information vs Knowledge
• Data– Streams of raw facts representing events, activities and transactions that are
captured, recorded, stored and classified but not organized to convey any specific meaning.
• Information– Data that has been organized so that they have meaning and useful to the
recipient in the processes such as making decisions. Information comes from the data that have been processed.
• Knowledge– Information that has been organized and processed to convey understanding,
experience and expertise as they apply to a current problem or activity
Primary Purpose of IS is to collect data, processes it into information then converts information into knowledge for a specific purpose.

• IT refers to the technological side of an IS which includes the hardware, software, database, networks and so on.
• IT can be viewed as a subsystem of an IS.
• Sometimes, the term IT is used interchangeably with IS.
IT = Hardware + Software + Database + Telecommunication + Network
IS = IT + People + Data + Procedures + Management

Function
1.31
Personal and Productivity systems
• To support individuals.
• Known as personal information management (PIM), system intends to support the activities that we perform to ease our life.
• A popular PIM tool is the personal digital assistant (PDA), with the functions such as calculators, calendars, schedulers and computer memory.
1.32
TPS
• Transaction Processing System.
• Ex: POS systems
• Face or perform repetitive information processing
• In banking, TPS cover deposit and withdrawals.
1.33
Functional and Management Information Systems
• Functional Systems: Put in place in each department to ensure that business strategies come to fruition in an efficient manner.
• Eg: HR system, Production systems, Marketing systems etc.
• MIS: used for planning, monitoring, and control. • Eg: Generate a sales forecast by region report• Help Marketing mgr for advertising and pricing.

• One of the most popular enterprise applications is Enterprise Resource Planning (ERP), which enables companies to plan and manage the resources of an entire organization.
• Other example such as CRM, KM and etc.
1.35
Interorganizational Systems (IOSs)
• The systems that connect two or more organizations, supported by EDIs.
• Enable computers to process large amounts of information that flow between organizations.
• In addition, they enable computers to ‘talk’ with other computers in different organizations.
• Connect buyers and sellers.
• Eg: order electronically, bill electronically and pay electronically.
1.36
Global Systems
• IOSs that connect companies located in two or more countries are referred as global information systems.
• Eg: If you have customers from other countries who buy from you online, you may need the support of a global system.
1.37
Very large and Special Systems.
• Eg: Natinal Health Care System in Denmark.
• In Denmark, all 5.3 million Danish residents and 150,000 healthcare professionals have access to the “Danish National e-Health Portal”. Its facilitates communications between doctors and patients, increase collaboration among healthcare providers, government agencies, pharmacies, healthcare professionals.
• The technology includes complicated software and hardware from IBM and other vendors.
1.38
• TPS automates routine and repetitive tasks that are critical to the operation of the organization, such as preparing a payroll, billing customers, Point-of-Sale, and Warehouse operations
• Data collected from this operation supports the MIS and DSS systems employed by Middle Management
• Computerizes the primary and most of the secondary activities on the Value Chain
• Primary purpose to perform transactions and collect data
1.39
• These systems access, organize, summarize, and display information for supporting routine decision making in the functional areas. Geared toward middle managers, MIS are characterized mainly by their ability to produce periodic reports such as a daily list of employees and the hours they work, or a monthly report of expenses as compared to a budget
• Typical uses would be in Replenishment, Pricing Analysis (Markdowns) and Sales Management
• Decisions supported are more structured• Primary purpose to process data into information
1.40
• ESS systems or Enterprise Information Systems (EIS) were originally implemented to support senior management. These systems have been expanded to support other managers within the enterprise
• At the senior management level they support Strategic Activities which deals with situations that may significantly change the manner in which business is done
1.41
An information system (IS) support each department in a corporation.
