Data association process, data association method, and data association apparatus

An association method executed by a computer, the association method comprising:

• identifying a second storage location associated with a first storage location by referring to a memory configured to store storage location association information indicating relevance between the first storage location and the second storage location where second data prepared at a second operation stage associated with a first operation stage and fourth data obtained by changing content of the second data are stored, the second storage location being identified when new data stored in the first storage location, where first data prepared at the first operation stage among a plurality of stages for manufacture of a product and third data obtained by changing content of the first data are stored, is approved;
• identifying latest data stored in the identified second storage location, and determining the latest data identified has been approved;
• and
• creating and recording in the memory, data association information indicating the relevance between the new data stored in the first storage location and the latest data among the data that is stored in the second storage location when the latest data has been approved.

An association apparatus comprising:

• a memory to store storage location association information indicating relevance between a first storage location where data prepared at a first operation stage among a plurality of stages for manufacture of a product is stored and a second storage location where second data prepared at a second operation stage associated with the first operation stage and fourth data obtained by changing content of the second data are stored;
• and
• a processor configured to:
• identify the second storage location associated with the first storage location by referring to the memory when new data stored in the first storage location is approved,
• identify latest data stored in the identified second storage location, and determine the latest data identified has been approved;
• and
• create and record to the memory, data association information indicating the relevance between the new data stored in the first storage location and the latest data among the data that is stored in the second storage location when the latest data has been approved.
