Abstract:
An inventory managing method for automatically performing an inventory managing process for a management object, comprising:creating a tree of nodes formed in a plurality of levels, each level corresponding to a different attribute, and each node storing an attribute value and an inventory quantity corresponding to a number of items with the respective attribute value; designating attributes and attribute values of an object as a retrieving condition; and executing an inventory retrieving process updating the inventory quantity of each node while searching each node corresponding to the retrieving condition, wherein each node with priority corresponding to a horizontal position of each node in levels corresponding to attributes that are not included in the retrieving condition is searched during searching each node on the binary tree data, wherein a tree structure is traced to a level corresponding to an attribute that is not included in the retrieving condition, and a retrieving process for supplying a deficiency is performed at a node of the second highest priority in the level when the inventory quantity of a terminal node is insufficient to supply a required quantity, wherein the inventory retrieving process is automatically performed according to a predetermined rule even in the case where the retrieving condition of the inventory retrieving process is not part of a query, by determining the attribute value of the management object.
