Relationship between Design and Analysis Classes

1. Dependency Relation

• Design classes build upon the findings of analysis classes.
• Analysis classes provide the foundation and requirements for the design phase.
• Without a clear understanding of the problem domain and requirements established by analysis classes, it’s challenging to create effective design classes.
• Analysis classes focus on identifying what the system needs to do and its essential components.
• Design classes then specify how those requirements will be implemented, detailing the structure, behavior, and interactions of the system’s components.

2. Iteration Relation

• The relationship between analysis and design classes is often iterative.
• As design classes are developed, they may uncover additional requirements or constraints that were not initially identified during the analysis phase.
• Feedback from the design phase may lead to revisions or refinements in the analysis classes to ensure alignment with the evolving understanding of the system.

In System Design, understanding the difference between design classes and analysis classes is crucial. Analysis classes are like detectives they investigate and understand the problem at hand. They focus on what the system needs to do, without diving into how it will be done. These classes help developers grasp the requirements and goals of the software. While the design classes are like architects they take the findings from analysis classes and create a plan for how the software will work.
