## Overview

MyGCD accepts number pairs through REST, records them, and enqueues them; SOAP processing consumes queued pairs, computes their GCDs, and stores results for list and sum queries. REST also lists submitted inputs, while session control limits concurrent users. The sampled source supports the REST service/DAO and SOAP service/DAO interactions; the SOAP endpoint-to-service link follows the documented API structure, and the queue is documented as ActiveMQ-backed.
