For managing folder and its related permission functionalities, let us assume that the following entities are involved:
- Folder
- FolderPermission
- FolderPermissionLink
The following diagram represents the entity relationship model for the folder entities through UML.
The following sections describe the low level details of these entities – e.g. the set of attributes, the code table associations, and the primary and foreign key details.
Folder
The entity Folder represents a standard folder object. The table below lists the various attributes that make up the Folder object. Note that the attributes type and statusCode have code table relationships to FolderType and RecordStatus respectively.

FolderPermission
The entity FolderPermission represents a permission object that can be assigned to a folder. For simplicity, other than the primary key attribute, this entity has only one attribute, name, which stores the name of the permission. Also note that this attribute has a soft relationship with the code table FolderPermissionName.

FolderPermissionLink
Since it is possible for a folder to have multiple permissions associated with it, the association between a folder and its permissions are captured in this entity.
