System Overview - Identifying classes from requirements

This system helps to identify classes from given software requirements. It breaks down requirements into meaningful objects (classes) that represent real-world entities or concepts. The goal is to organize requirements into a clear structure for easier design and development.

Components
User
actor
Provides software requirements input and receives identified classes output
Requirement Parser
service
Analyzes raw requirements text to extract key nouns and verbs
Class Identifier
service
Determines candidate classes based on parsed requirements
Class Repository
database
Stores identified classes and their attributes
Output Generator
service
Formats and delivers the list of identified classes back to the user

Failure Scenario
Component Fails:Class Repository
Impact:Identified classes cannot be saved or retrieved, causing loss of data and inability to provide output
Mitigation:Use database replication and backups to ensure availability and data recovery

Design Principle
This architecture separates concerns by parsing requirements, identifying classes, storing them, and formatting output in distinct components. This modular design improves clarity, scalability, and maintainability.
