High level vs low level design ?

High-level design and low-level design are two stages in the software design process that are used to define the architecture and functionality of a software system.

High-level design refers to the early stages of the design process where the overall architecture and requirements of the software system are defined. This includes defining the system’s modules, interfaces, and data structures, as well as its overall functionality and user interface. High-level design provides an abstract view of the system and focuses on the system’s major components and their interactions.

On the other hand, low-level design involves the detailed design of individual modules or components within the software system. This includes defining the algorithms, data structures, and programming language constructs to be used in each component. Low-level design focuses on the specific implementation details of the system and provides a more detailed view of how the system will function.

In summary, high-level design focuses on the overall architecture and functionality of the system, while low-level design focuses on the specific details of individual components within the system. Both are important stages in the software design process and contribute to the development of a high-quality, efficient software system.
