The model consists of a central cloud database and an embedded database running on mobile clients that share data via automatic synchronization - the embedded databases sync data between the cloud database and other embedded devices as it is captured or modified. The mobile database model is a merging of the cloud and embedded database models, combining the best aspects of each into an architecture that powers offline-first apps impervious to internet slowness and outages. With an embedded database, developers either have to build in data-sharing capabilities in their embedded apps or do without. Using an embedded database can be great for apps that are standalone in nature and that have data that rarely changes, but their lack of connectivity presents challenges for multiuser apps, where data changes frequently and must be shared with other users. By embedding the database in the app itself, you completely remove the need for a network connection while gaining the highest guarantees of speed and availability. This is where the database runs within the application installed on the mobile device. Embedded DatabaseĮmbedded database technology such as SQLite is another option for mobile app development. To guarantee a fast and reliable mobile app experience, you need to eliminate internet dependencies. When they go into areas with poor network connectivity, such as a subway station, airplane or tunnel, their apps become unreliable at best and useless at worst. And if the internet goes down, apps stop working altogether, frustrating users and costing business downtime.īecause of internet dependencies, the cloud database model presents challenges in meeting mobile app users’ expectations. If the internet slows, so do the apps that depend on it. The problem is that the model depends on the internet, which is inherently unreliable. The cloud database model offers a quick on-ramp to a standardized and distributed infrastructure that provides scale, elasticity and flexibility for mobile apps. In a cloud database model, mobile and IoT apps use a database that runs in the cloud. In general, because of their distributed nature and data model flexibility, NoSQL databases are ideally suited for mobile apps because of their speed and reliability. Additionally, NoSQL databases are distributed, meaning they can be deployed across multiple nodes, providing superior performance and reliability for applications. In contrast, a NoSQL database stores data as JSON documents, eliminating the need for a schema and allowing developers to change the database on demand as app requirements evolve. But relational rigidity comes with a price - app developers must conform their code to the schema, and any required changes to data results in time-consuming schema updates, making app updates challenging. NoSQLĪ relational database stores data in highly organized tables maintained by a rigid and fixed schema designed for consistency. When it comes to developing a mobile application, whether native, web based or hybrid, you need to choose a database that can provide the speed and reliability your users demand. You may wonder what we mean by “mobile database.” A database is a database, right? Providing a fast, reliable experience is key to the success of your mobile app, and using the right database - one built for mobile apps - is key to achieving it. These facts help emphasize that the margin of error is small when it comes to keeping users happy and engaged. And an older but still often cited Compuware study found that 84% of app users will abandon an app if it fails just two times. A report by Think Storage Now found that 70% of mobile app users will abandon an app that takes too long to load. In fact, according to a research study by mobile marketing analytics vendor AppsFlyer, nearly one in every two apps are uninstalled within 30 days, and a study by Andrew Chen found that losing 80% of mobile users is “normal” for all but the most popular apps.Ī big reason for the high rate of app abandonment is bad experience, particularly slowness and unreliability. Business of Apps reported that Google Play currently offers around 2.8 million apps and games, and the Apple App Store offers around 4.5 million.īut this huge volume of apps - and the increasing length of time that users are spending on them - means that users can be extremely selective with the apps they choose to engage with. And when it comes to which apps they use, there is no shortage of choices. TechCrunch recently reported that mobile users now spend between four and five hours - roughly a third of waking hours - on smartphone apps daily. Mobile app usage is increasing worldwide, not only in user volume, but in daily time spent on apps.
