Group-Based Schema

As a concept, group-based access control allows users to be organized into groups, with permissions assigned to groups rather than individual users. This approach simplifies permission management, especially in systems with complex access control requirements.

Extending the Schema for Group-Based Permissions​

In a system where users have permissions to create groups and manage complex hierarchical relationships among them, additional tables and structures would be needed to represent and manage these group-based permissions effectively.

Where there are multiple users with similar roles and permissions, assigning permissions at the group level can be more efficient than managing them individually.

Here's how you could expand upon the existing schema to incorporate groups:

Groups Table​

  • You would need a table to represent groups within the system.
  • Each group would have a unique identifier (group_id) serving as the primary key.
  • Additional fields could include group_name for the name of the group and description for a brief description of the group.
  • You might also include fields like created_at to track when the group was created.

User_Groups Table​

  • This table would establish the relationship between users and groups, similar to the User_Roles table.
  • It would contain foreign keys user_id referencing the Users table and group_id referencing the Groups table.
  • Additional fields might include assigned_by and assigned_at, indicating who assigned the user to the group and when.

Group_Groups (for nested groups)​

  • This table would handle the hierarchical relationships among groups.
  • It would have foreign keys parent_group_id and child_group_id, both referencing the Groups table.
  • Additional fields could include assigned_by and assigned_at, similar to the other relationship tables.

With these additional tables, users with the necessary permissions can create groups and manage their relationships. They can create nested groups by establishing relationships between groups using the Group_Groups table. Permissions can then be assigned to groups, and users within those groups inherit the permissions accordingly.

Managing Complex Hierarchies and Relationships​

Complex hierarchies and relationships can be managed by defining and organizing groups in a nested manner, allowing for granular control over permissions and access levels within the system. Users with appropriate permissions can create, modify, and delete groups as needed, effectively managing the group-based access control within the system.
