5. Consistency Models (Strong, Eventual, Causal)

1. Strong Consistency Implementation:
   • Create a relational database setup with ACID properties (e.g., PostgreSQL).
   • Write a script to test transactional consistency by simulating concurrent writes.
2. Eventual Consistency Simulation:
   • Build a simple distributed key-value store where nodes asynchronously replicate data.
   • Test consistency by performing writes and observing when all nodes eventually converge.
3. Causal Consistency Experiment:
   • Implement a versioning system (e.g., using vector clocks) to simulate causal consistency.
   • Create scenarios demonstrating causal relationships, such as a collaborative editing tool.
