Introduction to Information Systems
• Data is generally referred to as raw facts
• Information: collection of data organized in such a way that they have value beyond the
facts themselves
• Process: set of logically related tasks performed to achieve a defined outcome
- Turing data into information
• Knowledge: awareness and understanding of a set of information and the ways it can be
made useful to support a task
- The process of defining relationships among data to create useful information
requires knowledge
- Knowledge workers: individuals who understand how to use information for their
task
• Types of data:
- Alphanumeric
- Audio
- Image
- Video
• Select → organize → manipulate
• Data must be accurate to be used effectively
• An information system is a set of interrelated elements that:
- Collect
- Process
- Store
- Disseminate data and information
- Provides a feedback mechanism to monitor and control its operation to make sure it
continues to meet its goals and objectives
• Information systems can be divided into:
1. Personal
2. Group
3. Enterprise
• Key organizational complements:
- Well-trained workers
- System support
- Better teamwork
- Redesigned processes
- New decision rights
• Hardware- consists of computer equipment used to perform input, processing, storage,
and output activities
• Database- an organized collection of facts and information, typically consisting of two or
more related data files
- Can contain facts and information on customers, employees, inventory, sales, online
purchases, etc.
• Data warehouse- a database that stores large amounts of historical data in a form that

• Intranet- enable communication, collaboration, search functions, and information
sharing between member of an organization using a web browser
• Extranet- a network based on web technologies that allows selected outsiders to access
authorized resoures of a opay’s itraet
• Transaction- any business-related exchange, such as payments to employees and
suppliers and sales to customers
• Knowledge management systems- an organized collection of people, procedures,
software, databases, and devices that:
- Stores and retrieves knowledge
- Improves collaboration
- Locates knowledge sources
- Captures and uses knowledge
• System acquisition- process used to obtain the information system resources needed to
provide the services necessary to meet a specific set of needs
• System development- the atiity of uildig iforatio systes to eet users’ eeds
• Cybercriminals- motivated by the potential for monetary gain
