This document discusses a mobile solution developed by avanttic for a pharmaceutical company using a hybrid cloud and on-premises architecture. The solution involved using Oracle Mobile Cloud Service as the backend, Oracle Mobile Application Framework to develop cross-platform mobile apps, and Oracle Application Development Framework for the web application. This allowed the company to provide an offline mobile CRM app for salespeople, improve processes, and increase sales efficiency and ROI. Key lessons included the ability of Oracle MCS to easily integrate systems and solve mobile problems, and how MAF and ADF provided declarative development experiences.
