#systems design

Systems design is about planning and defining the components of a system, and how they'll work together. The documents here cover various aspects of systems design, including different models and techniques like use cases, object-oriented approaches, and data flow diagrams. They also provide examples of specific systems, such as a leave management system and a railway reservation system. Some documents discuss the differences between systems analysis and design, and how to approach problem analysis. There are also notes on computer security and its relation to systems design.
