Study Notes
Introduction to Information Systems
- Information technology (IT) refers to the combination of hardware, software, and services that people use to manage, communicate, and share information.
- IT is a critical component of modern life, just like water and air, and is essential for business success.
System Development
- Building an information system is a step-by-step process that requires careful planning and development.
- The process involves system analysis, where facts are collected and interpreted, problems are identified, and the system is decomposed into its components.
- System design involves planning a new business system or replacing an existing one, defining its components or modules to satisfy specific requirements.
System Analysis and Design
- A systems analyst plays a crucial role in planning, developing, and maintaining information systems.
- Analysts must possess excellent communication, analytical, and critical thinking skills.
- System analysis involves collecting and interpreting facts, identifying problems, and decomposing a system into its components.
- System design involves planning a new business system or replacing an existing one, defining its components or modules to satisfy specific requirements.
Types of Systems
- A system is a set of related components that produces specific results.
- Mission-critical systems are vital to a company's operations.
- Examples of systems include Enterprise Computing System (ECS), Transaction Processing System (TPS), Business Support System (BSS), Knowledge Management System (KMS), and User Productivity System (UPS).
Trends in IT
- Three major trends are driving business today, driven by the power of the internet.
- B2C (Business to Consumer) e-commerce enables consumers to purchase a wide variety of products and services online.
- B2B (Business to Business) e-commerce is many times greater in value.
IT Tools and Techniques
- Modeling produces a graphical representation of a concept or process that can be analyzed, tested, and modified.
- Prototyping tests system concepts and provides an opportunity to examine input, output, and user interfaces before final decisions are made.
- CASE (Computer-Aided Software Engineering) tools are powerful software that helps systems analysts develop and maintain information systems.
