The ServiceMax Go app architecture supports Android, iOS, and Windows platforms and is structured into multiple layers to ensure modularity and efficient data flow. At the client side, the app comprises a JavaScript layer that hosts the Go App UI, enabling user interactions. The app incorporates several feature modules including Zinc, SFM, OPDoc, Checklist, IB, and DataGuide, which deliver core functionalities; Zinc specifically provides offline data handling and synchronization capabilities exclusive to Android and iOS devices. The app leverages AI and Sync capabilities that interface with dedicated gateways, AI Gateway and Sync Gateway, serving as intermediaries to communicate with the Core server. The AI Gateway facilitates AI-driven processing, while the Sync Gateway manages data synchronization between mobile devices and the server. Additionally, the Zinc feature communicates directly with the Zinc server to handle offline data synchronization independently. The ServiceMax Core Server, in conjunction with the Go Console, manages core business logic and administrative configurations. This layered design ensures seamless data flow from mobile devices through gateways to servers, enabling real-time synchronization, AI functionalities, and robust offline support across platforms.
