Abstract
There is provided an information processing method for setting the exclusive control right of a data item by a specific process in a system in which a plurality of clients connected via a network share data including a plurality of data items. In this method, when a desired data item is designated so as to set its exclusive control right, data items which belong to layers lower than the designated data and are related to the designated data item are retrieved on the basis of the hierarchical structure information of the plurality of data items. Then, the exclusive control right is set for the designated data item and retrieved data items.
Claims14
An information processing method for setting an exclusive control right of a data item by a specific process in a system in which a plurality of processes that can communicate with each other via an information transmission medium share data including a plurality of data items, comprising:
- a first designation step of designating a desired data item for which the exclusive control right is to be set;
- a retrieval step of retrieving a data item which belongs to a lower layer with respect to the data item designated in the first designation step on the basis of hierarchical structure information of the plurality of data items;
- and
- a setting step of setting the exclusive control right by the specific process to the designated data item and the data item retrieved in the retrieval step.
An information processing apparatus for setting an exclusive control right of a data item by a specific process in a system in which a plurality of processes that can communicate with each other via an information transmission medium share data including a plurality of data items, comprising:
- a holding unit for holding hierarchical structure information of the plurality of data items;
- a first designation unit for designating a desired data item for which the exclusive control right is to be set;
- and
- a setting unit for setting the exclusive control right by the specific process to the designated data item and a data item which is related to the designated data item on the basis of the hierarchical structure information and belongs to a layer lower than the data item designated by the first designation unit.
