Organization hierarchy systems and methods

A method performed by a server storing multiple organizational hierarchies, the method comprising:

• receiving, from a user device, an access request to access a group model of a plurality of group models stored in a memory of the server, the group model associated with an organization of a plurality of organizations;
• sending, to the user device, hierarchy information indicating an organizational hierarchy that includes multiple group data structures of the group model, the hierarchy information sent responsive to the access request;
• receiving, from the user device and responsive to sending the hierarchy information, a query request indicating a group ID associated with the group model;
• and
• sending, to the user device and responsive to the query request, output data associated with a hierarchical structure of each group ID subordinate to the group ID associated with the group model.

An apparatus for accessing member information comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and storing processor-readable instructions that, when executed by the at least one processor, are configured to cause the at least one processor to:
• receive transmission from a user device of an access request to access a group model of a plurality of group models stored in a memory of the apparatus, the group model associated with an organization of a plurality of organizations;
• send hierarchy information indicating an organizational hierarchy that includes multiple group data structures of the group model, the hierarchy information received responsive to the access request;
• and
• send output data associated with a hierarchical structure of each group ID subordinate to a group ID associated with the group model, the output data received responsive to a query request associated with the group ID.
