Understanding User Data Storage in Apps

Users generate data as they interact with apps. It’s this data that apps usually need to save or access in order to function properly and offer the best user experience possible. This includes personal settings as well as media, among other documents. It can also be used to monitor the number of clicks, purchases, and other conversions within the application. There are many ways to gather this information that include asking the user for it, determining it based on on-site behavior or purchasing it from a third party. The ideal customer data should be centrally stored and in a standard format to facilitate integration and exchange between applications. There are currently emerging customer data profiles that are standardized by industry sector to determine the data model to be used for this purpose.

There are many ways to store data, and the system used by an application will affect the way the user interface appears. The most popular is file storage, in which the data is kept in folders and files, arranged in an order. Hard disk drives as well as cloud storage services like Google Drive or Microsoft OneDrive use this approach. Another method is block storage, where the data is split into blocks which can be saved anywhere on the storage infrastructure, with identifiers that allow them to be quickly identified and taken action.

Early systems included tools that provided precise information about the characteristics of the storage medium in textual format. Modern systems, such as Android, provide visualizations for these functions, such as capacity/usage and lifetime. The visualisations for capacity/usage are usually horizontally bar charts that are stacked. Lifespan visualisations are usually presented as a circular pie graph or variants such as doughnut charts.
