How would you business-wise divide the real estate appraisal system into parts? There is an object, organizations with branches, user roles — how would you structure this?

The following business layers and parts can be distinguished for the real estate appraisal system:

1. Real estate objects — entities describing apartments, houses, plots, etc. They contain characteristics of the object, appraisal history, photographs.

2. Organizations and branches — companies conducting appraisals, with the ability to have multiple branches. This allows for access control and data management based on geography.

3. Users and roles — a role system (e.g., administrator, appraiser, manager) that defines access rights to objects, reports, and settings.

4. Appraisal and reports — a module where the cost calculation occurs, results are stored, and documents are generated.

5. Audit and logging — tracking user actions and data changes.

This separation helps manage access, scale the system, and maintain business logic separately from technical details.
