1. A data management device storing data, managing a plurality of users as a group and opening the data to a user who belongs to a designated group, the data management device comprising:
- an association setting unit configured to set association between first data which is previously set to be opened by a first user and at least one of second data;
a determination unit configured to determine, from a plurality of first groups to which the first data is set to be opened, at least one group in common with one or more groups to which the first user setting association belongs; and
an opening unit configured to open the second data to a second user belonging to the at least one group in common determined by the determination unit, after the association setting is performed by the setting unit,wherein the association setting unit is configured to set the at least one group in common determined by the determination unit as a group to which the second data is set to be opened, such that the second user belonging to the at least one group in common is allowed to open the second data, and wherein determination of the at least one group in common by the determination unit, and setting of the at least one group in common by the association setting unit as the group to which the second data is set to be opened, is performed upon opening of the first data by the first user, such that updating of the at least one group in common between openings of the first data by the user is avoided.

Abstract
Contents can be opened to a suitable group by a simple operation. A data management method allows a plurality of users to browse stored data. The method includes setting association of first data which is previously set to be opened and at least one second data. Third groups to which these second data is opened are determined based on first groups of the first data set to be opened and second groups to which a user setting the association belongs. Then, the second data are opened to a user who belongs to the third groups.

4. A data management system comprising:
-
a management device storing data, managing a plurality of users as a group and opening the data to a user who belongs to a designated group; a plurality of information processing devices coupled to the data management device through a network; and an association setting unit configured to set association between first data which is previously set to be opened by a first user and at least one of second data; wherein the management device includes a determination unit configured to determine, from a plurality of first groups to which the first data is set to be opened, at least one group in common with one or more groups to which the first user belongs, wherein the information processing device includes an opening unit configure to open the second data to a second user belonging to the at least one group in common determined by the determination unit, after the association setting is performed by the setting unit, and wherein the association setting unit is configured to set the at least one group in common determined by the determination unit as a group to which the second data is set to be opened, such that the second user belonging to the at least one group in common is allowed to open the second data, and wherein determination of the at least one group in common by the determination unit, and setting of the at least one group in common by the association setting unit as the group to which the second data is set to be opened, is performed upon opening of the first data by the first user, such that updating of the at least one group in common between openings of the first data by the user is avoided.

5. A method for managing data performed by a data management device storing data, managing a plurality of users as a group and opening the data to a user who belongs to a designated group, the method comprising:
-
setting association between first data which is previously set to be opened by a first user and at least one of second data; determining, from a plurality of first groups to which the first data is set to be opened, at least one group in common with one or more groups to which the first user belongs; and opening the second data to a second user belonging to the at least one group determined to be in common, after the association between the first data and the at least one of second data is set, wherein the at least one group determined to be in common is set as a group to which the second data is set to be opened, such that the second user belonging to the at least one group in common is allowed to open the second data, and wherein determination of the at least one group in common as the group to which the second data is set to be opened, is performed upon opening of the first data by the first user, such that updating of the at least one group in common between openings of the first data by the user is avoided. - View Dependent Claims (6, 7, 8)
