Question
Explain the principles of data consistency models in distributed systems, such as the CAP theorem. Provide real-world examples of systems that fall into each category (Consistency, Availability, Partition Tolerance).
Expert Solution

Step 1: Introduction to Data Consistency Models and CAP Theorem:
Data consistency models play a role in ensuring the reliability and coherence of distributed data across nodes.
The CAP theorem, put forward by computer scientist Eric Brewer helps us understand the tradeoffs involved in distributed systems when it comes to three properties:
Consistency, Availability and Partition Tolerance.
