Enterprise Mobility Services (EMS) is a multi-tier framework that first shipped with RAD Studio XE7. This white paper is designed to provide you, the software professional, with the information you need to get started with EMS today. You will learn how EMS interfaces with the various technologies necessary to support your applications, and why this approach is so valuable in today's distributed computing landscape. The paper continues by showing you how to get started with your EMS development including how to install EMS and make basic calls into this service. Importantly, these calls are standard REST REpresentational State Transfer) calls, which can be emitted by any language or framework that understands HTTP (HyperText Transfer Protocol). After a brief discussion of REST, you will learn how to make some of these basic calls using a browser, RAD Studio's REST Debugger, and a Delphi application.
