What is system design? What are the major tasks performed during system design? Explain.
System design in the context of Object-Oriented Analysis and Design (OOAD) refers to the process of defining the architecture, components, interfaces, and data for a system to satisfy specified requirements. It serves as the bridge between the analysis phase and implementation, translating the conceptual model created during analysis into a blueprint for constructing the software system. In OOAD, system design uses object-oriented principles to ensure modularity, reusability, and flexibility of the system.
System design is typically divided into two broad areas: high-level design (also known as architectural design) and low-level design (also known as detailed design). High-level design focuses on defining the overall structure of the system, including subsystems, components, and their interactions. Low-level design deals with the internal design of individual classes, methods, and attributes.
The major tasks performed during system design in the OOAD process are as follows:
