Transactional Context pattern
Description
Implement the Transactional Context design pattern which ensures that a set of operations are executed within a transaction context, maintaining atomicity, consistency, isolation, and durability (ACID properties). This pattern is essential for managing transactions in complex systems, providing a mechanism to rollback in case of failures, and ensuring that data remains consistent.
Main elements of the pattern include:
- Transaction: Represents the transaction boundary, containing operations to commit or rollback changes.
- Transactional Context: Maintains the state of the transaction, coordinating the operations and ensuring that they adhere to ACID properties.
- Transaction Manager: Manages the lifecycle of transactions, including beginning, committing, and rolling back transactions.
- Operations: The individual operations that need to be executed within the transaction context.

Acceptance Criteria
- Implement classes for Transaction, Transactional Context, Transaction Manager, and Operations as described in the pattern.
- Ensure that the implementation adheres to the ACID properties.
- Provide unit tests demonstrating the correct behavior of the transactional context, including scenarios for commit and rollback.
