- 3. Key aspects: 1. System Boundaries This defines what is considered inside the system (the software being developed) and what lies outside (external entities, other systems, or hardware components.
- 4. 2. Entities These are the actors or components that interact with the system. They can include users, other software systems, databases, hardware devices, or even external services like APIs.
- 5. 3. Relationships Context models illustrate how these entities interact with each other and with the system itself. This includes communication channels, data flows, dependencies, and any constraints or rules governing these interactions.
- 6. 4. Dependencies It captures dependencies between the software system and external entities, such as reliance on specific hardware configurations, network protocols, or third-party services.
- 7. 5. Constraints These are conditions or limitations that impact the design or behavior of the system, such as performance requirements, security policies, regulatory compliance, or technological limitations.
- 8. Conclusion: By creating and analyzing a context model early in the software development lifecycle, teams gain a clearer understanding of the system's operational environment. This understanding helps in making informed design decisions, identifying potential risks, defining system boundaries, and ensuring that the software integrates effectively with its surrounding ecosystem.
