I have just published my first OTN Tech Article where I present a use case that demonstrates how Oracle Process Cloud Service (Oracle PCS), Oracle Mobile Cloud Service (Oracle MCS) and Oracle Mobile Application Framework (Oracle MAF) can be use together to expose an Oracle PCS process instance as a web service and consume it from an external system, web application or mobile application.
"Oracle Process Cloud Service is a Platform as a Service (PaaS) provided by Oracle Cloud, allows you to rapidly design, automate, and manage business processes in the cloud."
"Oracle Mobile Cloud Service is Oracle's Mobile Backend as a Service (MBaaS) and enables companies to create and deploy scalable, robust, and secure mobile applications quickly and easily."
"Oracle Mobile Application Framework is a hybrid mobile framework that provides a visual and declarative development experience for the rapid development of multi-platform applications"
