This course introduces the core concepts of Software Design and Development (SDD), focusing on how software problems are analyzed, structured, and translated into functional systems. It is designed for beginners who want to understand the early stages of software engineering and system design.

You will learn how to approach software problems using structured analysis methods, starting with understanding the problem and breaking it down into manageable components. The course explains the top-down approach to software development, which helps developers design systems in a logical and organized way.

A key focus is placed on system modeling techniques, including context diagrams and data flow diagrams (DFDs), which are used to visualize how data moves through a system. It also introduces structure diagrams and data dictionaries, which help define system components and data relationships clearly.

In addition, the course covers essential computing foundations such as data types and number systems. You will learn how binary and decimal systems work, including converting values between them—an important skill in computer science and programming.

By the end of this course, learners will understand how software systems are designed from problem definition to structured modeling and data representation. It is ideal for students beginning their journey in software engineering, computer science, or IT development.
