Three Ways Retailers Use MongoDB for Their Mobile Strategy`: Retailers use MongoDB to tackle omnichannel data challenges, achieving data centricity across channels. This is exemplified by Marks & Spencer's re-platforming of its Sparks mobile application backend onto MongoDB Atlas, enabling real-time access to customer behavior and trends. Additionally, retailers deliver a cohesive omnichannel retail brand experience through workforce enablement mobile apps that sync data in-store, such as 7-Eleven's custom mobile device using MongoDB Realm, which enables efficient order management and visual merchandising. Furthermore, retailers deal with network consistency issues by leveraging MongoDB Realm's local data persistence and Atlas Device Sync, allowing for bi-directional device to cloud synchronization even in areas with poor network connectivity.
