Multiplexing of dedicated communication channels for multiple entities

A computer-implemented method for multiplexing of data between entities, comprising:

• establishing a communication channel over which a plurality of entities exchange data associated with a particular individual;
• initiating, by a first client computing device at a first entity of the plurality of entities, a first request to share data associated with the particular individual with a second client computing device at a second entity of the plurality of entities;
• initiating, by the first client computing device at the first entity, a second request to share data associated with the particular individual with a third client computing device at a third entity of the plurality of entities;
• receiving an indication from the second client computing device at the second entity that the first requested is accepted;
• receiving an indication from the third client computing device at the third entity that the second requested is accepted;
• sharing, in response to the first request being accepted, a first portion of an aggregate record associated with the particular individual with the second client computing device at the second entity;
• and
• sharing, in response to the second request being accepted, a second portion of the aggregate record with the particular individual with the third client computing device at the third entity,
• wherein the first portion and the second portion of the aggregate record shared is dependent on data sharing rules defining:
• shared data in the aggregate record that is synchronized between the plurality of entities when added or modified by a client computing device at one of the plurality of entities;
• linked data in the aggregate record that is i) nonsynchronous between the plurality of entities, and ii) provided for display at the plurality of entities independent of the one of the plurality of entities at which the linked data was added or modified in the aggregate record;
• and
• entity-specific data that is i) nonsynchronous between the plurality of entities and ii) provided for display only at the entity that is associated with the entity-specific data.

Non-transitory computer readable memory media storing instructions executable by one or more processors for:

• establishing a communication channel over which a plurality of entities exchange data associated with a particular individual;
• initiating, by a first client computing device at a first entity of the plurality of entities, a first request to share data associated with the particular individual with a second client computing device at a second entity of the plurality of entities;
• initiating, by the first client computing device at the first entity, a second request to share data associated with the particular individual with a third client computing device at a third entity of the plurality of entities;
• receiving an indication from the second client computing device at the second entity that the first requested is accepted;
• receiving an indication from the third client computing device at the third entity that the second requested is accepted;
• sharing, in response to the first request being accepted, a first portion of an aggregate record associated with the particular individual with the second client computing device at the second entity;
• and
• sharing, in response to the second request being accepted, a second portion of the aggregate record with the particular individual with the third client computing device at the third entity,
• wherein the first portion and the second portion of the aggregate record shared is dependent on data sharing rules defining:
• shared data in the aggregate record that is synchronized between the plurality of entities when added or modified by a client computing device at one of the plurality of entities;
• linked data in the aggregate record that is i) nonsynchronous between the plurality of entities, and ii) provided for display at the plurality of entities independent of the one of the plurality of entities at which the linked data was added or modified in the aggregate record;
• and
• entity-specific data that is i) nonsynchronous between the plurality of entities and ii) provided for display only at the entity that is associated with the entity-specific data.
