👔Phase 3: Design

The design phase of the Software Development Life Cycle (SDLC) is where a detailed plan for the software development process is created, based on the requirements gathered in the previous phase.

Design Phase Activities

• System design: This involves creating a high-level design for the software system, including its architecture, components, and interfaces. The system design is intended to provide a blueprint for the software development process and is typically documented in a system design document.

• Software design: This involves designing the software components and modules required to implement the system design. The software design is intended to provide a detailed plan for the development of the software and is typically documented in a software design document.

• Database design: This involves designing the database schema and data structures required to support the software system. The database design is intended to ensure that the software system can efficiently store, retrieve, and process data, and is typically documented in a database design document.

• User interface design: This involves designing the user interface for the software system, including the layout, navigation, and visual design. The user interface design is intended to ensure that the software system is intuitive and easy to use, and is typically documented in a user interface design document.

The output of the design phase is a set of documents that provide a detailed plan for the software development process. These documents typically include the system design document, the software design document, and the database design document.
