A method includes a digital subscription management system (DSMS) receiving from a source system a request to perform an edit of at least one data object, the DSMS sending a request for response (RFR) to subscribing systems having a copy of the at least one data object, the DSMS receiving a response from the subscribing systems, and the DSMS performing the edit.

A data management system receives a status update request in which a target is specified and executes status update processing of updating a status of the target specified in the status update request. The status update processing includes transaction processing that is processing of updating first information and second information in an ACID (Atomicity, Consistency, Isolation, Durability) transactional manner. The first information is a first object group (one or more first objects) for each target. The first object is data that represents the status of the target. The second information is a second object group (one or more second objects) for each target. The transaction processing includes first processing of creating, updating, or deleting the first object corresponding to the specified target, and second processing of adding the second object including at least one of a content of the first processing and a summary of the first object to the second object group corresponding to the specified target.
