Section 1 | Introduction to Information Systems

In this section, we will build a strong foundation for understanding Systems and Information Systems before starting programming. We will learn: • What is a System? • System Components • System Boundaries and Objectives • The Basic System Model: Input → Process → Output • Feedback and Control • Types of Systems • Introduction to Information Systems • What is SDLC? • SDLC Phases: Planning, Analysis, Design, Implementation, Testing, Deployment, and Maintenance • How a problem can be transformed into a complete system step by step The goal is to understand how systems work, how they are classified, and how we can develop a system systematically using the Software Development Life Cycle (SDLC). By the end of this section, you will have the conceptual foundation needed to start building and understanding Information Systems practically.
