What roles can be used to differentiate user types before developing an application?

The option that includes Abstract, Job, Data, and Duty is correct as these roles effectively capture the nuances of user types in the context of application development.

• Abstract roles represent high-level categorizations that define a common set of capabilities applicable to different specific roles. This allows developers to create a flexible structure that can accommodate various user types based on their essential functions.

• Job roles define the specific work performed by a user within an organization. By differentiating jobs, developers can tailor applications to meet the unique needs associated with various positions, ensuring that user access and functionalities align with their responsibilities.

• Data roles are critical for managing the access and permissions related to sensitive information within an application. By establishing how users interact with data sets, developers can create applications that safeguard against unauthorized access while still providing necessary insights and functionality to authorized users.

• Duty roles focus on the specific tasks or responsibilities that users have within their job functions. This granularity allows for even more precise control over what users can see and do within an application, aligning application features with users' actual duties.

In summary, this combination of roles provides a comprehensive framework for differentiating user types, ultimately leading to more effective application development and deployment that aligns with
