Mobile app usage continues to rise globally, with users spending significant portions of their day on various apps, which are abundant in number on platforms like Google Play and the Apple App Store. However, many apps face high abandonment rates due to poor user experiences, such as slowness and unreliability, highlighting the critical need for fast and dependable apps. To achieve this, selecting the right database is essential, with NoSQL databases generally preferred for their flexibility and performance benefits over traditional relational databases. Cloud databases offer scalability but depend heavily on internet connectivity, which can lead to issues in areas with poor network access. Conversely, embedded databases provide speed and availability by operating offline but pose challenges for apps needing frequent data updates and sharing. The mobile database model integrates the strengths of both cloud and embedded databases, supporting offline-first applications through automatic data synchronization and peer-to-peer features, ensuring consistent and reliable user experiences. Couchbase offers a mobile database solution that combines the advantages of a cloud NoSQL database with edge capabilities, as demonstrated by its application in Halliburton's operations, where it improves efficiency by enabling data synchronization in environments with limited connectivity.
