Milline on andmeobjekti roll süsteemis ja millistes stsenaariumides seda kasutatakse?

The Data Object in Android is a structure or class used for storing and transferring data within the application. It typically contains only fields and access methods (getters and setters), without behavior logic.

Application scenarios:

• Transferring data between Activity or Fragment via Intent or Bundle.
• Saving UI state.
• Modeling data obtained from a database or network.

For example, a user model class:

data class User(val id: Int, val name: String, val email: String)

Such an object is convenient for transferring information and working with it in the application.
