Leading Solution
Apelon’s Distributed Terminology System
DTS 4, Apelon’s Distributed Terminology System (DTS), is a major revision to the world’s leading healthcare terminology management platform. DTS 4 has been designed to meet emerging enterprise requirements for creating, maintaining, and deploying terminologies with local enhancements into enterprise, regional, and national distributed application environments.
DTS 4’s improved functionality, capabilities, and ease-of-use is why DTS is the preferred platform for the comprehensive management of both standard and local/proprietary terminologies. Because DTS is open source, it provides significant cost, integration and adoption advantages compared to proprietary solutions.

Enterprise-Scale Deployment
Designed for enterprise, regional, and national roll-outs, DTS scales from a single department to country-wide infrastructure without re-architecture.
