As users interact with apps they generate data. Apps typically need access to or save this data in order to click here to read function properly and to provide the best user experience. These include personal settings as well as media, among other documents. This information can be used to track clicks and purchases within the application. This data can be obtained through a variety of methods, including by asking the user to provide it, assuming it based on their behavior on the site or purchasing it from an outside. The ideal customer data should be stored centrally and in a standardised format that allows for easy integration and exchange between different applications. There are new standards for data profiles of customers by industry sectors that could help define the data models to be used.
There are many ways to store data, and the system used by the application will influence how the user interface looks. The most commonly used is the storage of files, in which the data is stored as folders and files, which are organized in an order. Hard disk drives as well as cloud storage like Google Drive or Microsoft OneDrive make use of this method. Block storage is a different method in which data is split up into blocks and stored in any storage infrastructure. They are identified using identification numbers to make them easy to locate and take action on.
The early systems came with built-in tools that report specific information about the properties of the storage medium in textual format. Modern systems, such as Android provide visualisations for these functions, including capacity/usage as well as lifetime. The visualizations of capacity/usage are typically displayed as horizontal bar charts, while the duration is presented as a circular pie chart or its variants like doughnut charts.
