Methods and Systems for Updating a Graph Data Structure

A method comprising:

• determining a target object read request for querying a first data structure, the target object read request comprising a target identifier of a target object;
• determining a first object identifier of a first object in the first data structure based on the target identifier;
• providing a response to the target object read request, wherein the response includes at least the first object;
• determining association information between the first object and a second object;
• determining whether the association information between the first object and the second object is stored in a second data structure;
• and
• responsive to no association information being identified between the first object and the second object in the second data structure:
• generating new association information indicative of the association between a first entity object and a second entity object, the new association information including the first identifier of the first object and a second identifier of the second object;
• generating an association write request to write the new association information to the second data structure;
• providing the association write request to the second data structure.
