What approaches to organizing and storing data do you use or are familiar with?

In Android, different approaches are used for organizing and storing data depending on the task:

• SharedPreferences — for storing small key-value pairs, such as user settings.
• File system — for saving files, images, documents.
• SQLite — an embedded relational database for structured data.
• Room — an abstraction over SQLite with a convenient API and support for LiveData.
• ContentProvider — for data sharing between applications.
• DataStore — a modern alternative to SharedPreferences with support for asynchronous access and type safety.

The choice depends on the volume, data structure, and requirements for performance and security.
