Final Takeaways & Close

What This Project Demonstrates

Pattern Recap
Object Variation
Strategy + Template Method

Statistics and trading rules vary independently, while rolling calculations share one lifecycle.

Object State
Composite + State + Singleton

Reporting, position transitions, and decision records each have one clear owner.

Message Flow
Enterprise Integration Patterns

Camel makes polling, filtering, splitting, selective consumption, aggregation, and failure handling explicit.

Final Takeaways
Object patterns and EIPs are complementary
GoF patterns shape the internal object model; Enterprise Integration Patterns shape how those objects move through a system.
The best pattern choices matched change points
Statistics, trading strategies, engines, and channels were the likely extension points, so the design isolates each one.
The demo proves behavior, not just structure
Different outputs from the same feed show that routing, aggregation, strategy, and state transitions are actually working together.
