    What is a System?

    • A system comprises interrelated components functioning together to achieve common objectives.
    • Systems possess clearly defined boundaries.

    Information Concepts

    • An information system (IS) collects, manipulates, stores, and disseminates data/information to meet objectives.
    • Information systems are used extensively by diverse professionals, including sales representatives, managers, and financial advisors.
    • Information systems are pivotal tools for career success, empowering businesses to boost revenue and curtail costs.
    • Information is considered one of an organization's most valuable resources, often mistaken with data.

    Data, Information, and Knowledge

    • Data is the raw facts, comprising fundamental building blocks of information.
    • Information organizes data in a way that offers value beyond its constituent facts.
    • A process represents a set of logically linked tasks, transforming data into information.
    • Knowledge embodies the awareness and comprehension of an information set.
      • Data is transformed into information through applying knowledge to organize and manipulate it (Figure 1.2).

    Characteristics of Valuable Information

    • Accurate & complete information are crucial for sound decision-making, preventing possible financial losses.
    • Some characteristics take precedence over others depending on the specific needs and context.

    The Value of Information

    • Information's value is directly linked to its contribution in supporting decision-makers in achieving organizational goals.
    • Robust information assists individuals and organizations in more efficient and effective task execution.

    What is an Information System?

    • A collective, interrelated group of components including inputs, processes, and outputs, capable of gathering, manipulating, storing, and delivering data/information, whilst providing a feedback mechanism for refining system operations.

    Input, Processing, Output, and Feedback

    • Input involves gathering and capturing data.
    • Processing converts raw data into meaningful outputs.
    • Output entails the generation of useful information, usually in the form of reports or documents.
    • Feedback represents the information the system provides for correcting inputs or processes.

    Three Fundamental Types of Information Systems

    • Personal IS enhances productivity for individuals.
    • Group IS facilitates collaboration among team members.
    • Enterprise IS enables and sustains structured interactions within and outside of organizations (e.g., employees, customers, suppliers, government agencies).

    Manual and Computerized Information Systems

    • Information systems can be either manual or computerized.
    • Manual systems, for instance, involve investment analysts manually creating graphs and trend lines.
    • Computerized systems often track stock indexes and market trends to predict opportune times for purchasing or selling stocks.

    Computer-Based Information Systems (CBIS)

    • A CBIS constitutes a collection of hardware, software, telecommunications technology, people, and procedures, aimed at gathering, manipulating, storing, and processing data into pertinent information.

    Computer-Based Information Systems (CBIS): Elements

    • Hardware encompasses physical computer equipment.
    • Software encompasses the computer programs directing operations.
    • Databases collate facts and pertinent data into organized files (often consisting of two or more interconnected data files).
    • People is the most significant element, representing active users of technology and utilizing the system.
    • Procedures refer to the rules, policies, methods guiding system usage.
    • Telecommunications describes networks and the Internet for enabling electronic communication.
    • Intra/Extranet functionalities aid in data exchange inside and outside an organization to access authorized system resources.

    Business Information Systems

    • Common business information systems often include or are used concurrently with e-commerce, transactions, & mobile commerce, and management & decision-support functions.
    • Other, more niche systems, such as VR technology, serve particular needs.

    Electronic and Mobile Commerce

    • E-commerce encompasses a wide variety of online business transactions, including business-to-business (B2B), business-to-consumer (B2C), consumer-to-consumer (C2C), and business-government (B2G) transactions.
    • Mobile commerce (m-commerce) specifically refers to transactions conducted via handheld devices.
    • E-business utilizes information systems to support all activities within a company.

    Enterprise Systems: Transaction Processing Systems and Enterprise Resource Planning

    • TPS systems record and process business-related exchanges (e.g., payments, sales).
    • Enterprise resource planning (ERP) systems manage various aspects of a company's operations (e.g., production, finance, human resources).

    Information and Decision Support Systems

    • Management information systems (MIS) generate summaries of routine information.
    • Decision support systems (DSS) facilitate problem-specific decision-making.

    Specialized Business Information Systems

    • Knowledge management systems (KMSs) facilitate the storage and use of an organisation's knowledge.
    • Artificial intelligence (AI) involves creating systems that function similarly to human intelligence – like vision systems, robotics, learning systems, specialist AI tools like expert systems and neural networks which use the concept of AI; and Natural language processing enabling text & speech understanding and processing by systems.
    • Virtual reality and multimedia create immersive experiences.
    • Expert systems simulate the capabilities of human experts.

    Systems Development

    • The processes of establishing and modifying existing business systems.
