In the Waterfall model, a traditional software development lifecycle (SDLC) methodology, the design phase follows the requirements phase. During the design phase, the focus is on creating a detailed specification of the system to be developed. This includes:
* Architectural Design: Outlining the overall structure of the system.
* Interface Design: Defining how the software components will interact with each other and with users.
* Component Level Design: Specifying the behavior of individual components.
* Data Structure Design: Establishing how data is organized within the system.
The deliverable produced during this phase is a comprehensive design document that describes the architecture, components, interfaces, and data structures of the application in detail. It serves as a blueprint for the next phase of the Waterfall process, which is implementation (coding).
