PROBLEM TO BE SOLVED: To make a shortcut to a document before replacement effective to a document after replacement in replacing the document having the shortcut with the other document. SOLUTION: When the creation of a shortcut to a document is instructed, the shortcut including the document ID of the document is created, and the attribute of the document (a shortcut creation history) is updated. When the deletion of the document into a trash can and the creation of a proxy entity of the document are instructed thereafter, a proxy entity in which a user ID set in the document to be deleted is set is created. The proxy entity is created in the same folder as that for storing the document to be deleted. In addition, the document ID of the document to be deleted is replaced with the document ID of the created proxy entity, and the document to be deleted is moved to the trash can.
