Difference between Design classes and Analysis classes

Real-World Examples of Analysis and Design Classes

This table illustrates the key differences between analysis classes and design classes:

Aspect	Analysis Classes	Design Classes
Purpose	Identify requirements and understand problem domain	Define how the system will be built and operated
Focus	What the system needs to do (functional requirements)	How the system will accomplish its tasks (implementation details)
Level of Detail	High-level, focusing on entities, attributes, and relationships	Detailed, specifying methods, attributes, and interactions
Implementation	No implementation details, abstract representation	Implementation details specified, concrete representation
Dependencies	Depends on user needs, business processes, and external systems	Builds upon analysis classes, translating requirements into a structured plan
Deliverables	Use cases, user stories, domain models	Class diagrams, sequence diagrams, design patterns
Timing	Early stage of system development, before design	Follows analysis, comes before implementation
Flexibility	More flexible and subject to change during analysis phase	Less flexible, changes may require more effort during design phase

What is the Difference Between Design Classes and Analysis classes?

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.
