Study Notes
Introduction to Information System
- A system is a collection of parts that interact to achieve goals.
- Information Systems (IS) improve organizational processes, making operations simpler and more efficient.
- A subsystem is an individual component within a larger system focused on specific tasks.
Types of Systems
- Natural Systems: Created by nature (e.g., typhoons, floods).
- Man-Made Systems: Designed by humans (e.g., transportation systems, education and health systems, computer systems).
Data vs. Information
- Data: Raw, unprocessed facts in various forms (numbers, text).
- Information: Organized and processed data that provides meaning and aids decision-making.
- Data must be collected and processed to become useful for making decisions.
Computer System
- An integrated set of hardware and software working together.
- Provides necessary components for computing performance.
Information System Functions
- Collects, stores, retrieves, processes, manages, disseminates, and analyzes information for operational functions and decision-making.
Master Data
- Permanent data stored in IS includes:
- Customer master data
- Employee master data
- Subject master data
Capabilities of an IS
- Processes transactions quickly and accurately.
- Manages significant storage with easy access.
- Supports decision-making and eases information overload.
- Facilitates effective communication through networks.
- Enhances organizational memory and fosters a culture of learning.
Components of Information Systems
- Hardware: Physical components (servers, workstations, networks).
- Software: Programs controlling hardware.
- Data: Facts that systems transform into useful information.
- Procedures: Instructions describing tasks performed by users and IT staff.
- People: Stakeholders interested in the system's functions.
Computer-Based Information System (CBIS)
- Combines hardware, software, databases, telecommunications, and procedures for data management.
- Includes various models of software delivery such as freeware, shareware, and proprietary software.
Developing Information Systems
- Involves the creation and modification of information systems, adhering to the System Development Life Cycle (SDLC).
- System testing is critical for performance assessment.
- Implementation involves deploying the system after successful testing and user training.
- Maintenance focuses on reducing operational costs and optimizing performance through ongoing assessment.
System Development Life Cycle (SDLC)
- A project management framework outlining stages of information system development from feasibility studies to system maintenance.
- Key phases include:
- Requirements analysis and definition
- System design and development
- System testing and evaluation
- System implementation and deployment
- System maintenance and support.
Information System Security
- Involves safeguarding information and systems against unauthorized access, malware, and breaches.
- Essential for maintaining the integrity and confidentiality of data.
