Abstract: A policy can be easily and appropriately set. A policy setting control device 100 that controls setting of a policy for controlling access to a resource includes a processor. The policy includes a resource to be accessed, a subject who accesses the resource, and an access operation. The processor receives an input policy 11 which is a candidate to be newly set, acquires an attribute value corresponding to values of a subject and a resource included in the input policy 11, generates one or more post-conversion policies 103 by changing the values of the subject and the resource included in the input policy 11 to the acquired attribute value, and sets the input policy as a new policy when all the generated post-conversion policies 103 are consistent with an existing policy.

Abstract: A distributed transaction in which appropriate patterns are combined without modifying implementation of a management system even when a service characteristic of a participating system changes. A management system receives input of a distributed transaction flow defining respective call sequential numbers of participating systems and service characteristic information representing respective service characteristics of the participating systems. The management system specifies an applied pattern for each of the participating systems based on pattern information including information for each pattern that represents a constraint condition of a service characteristic of a participating system as a call target. The applied pattern is a pattern satisfying the constraint condition corresponding to the service characteristic of the participating system. The management system generates a pattern-applied call program for each of the participating systems, and generates a distributed transaction program based on the pattern-applied call programs and a call sequence of the participating systems.

Abstract: A tag domain presentation device holds a data usage log table that stores a department to which a user belongs, information about an application for each user, a search tag used by the application, data information corresponding to the search tag, a given tag corresponding to each data piece, and user evaluation information related to the given tag. The tag domain presentation device generates a usage viewpoint extraction log table that is filtered from a data usage viewpoint from a record of the data usage log table, and generates a usage tendency evaluation table from the usage viewpoint extraction log table based on usage information about the user and the application for each department of the data and the user evaluation information, and presents a search formula of the tag for each department common as a data usage viewpoint based on the information.

Abstract: A computer system manages a data lake storing collected data, which is obtained from a data source, a data catalog storing first catalog data, and an asset catalog storing second catalog data. The computer system comprises: a catalog generation module configured to generate the data catalog, and the asset catalog; and a catalog link generation module configured to associate, in a case where at least one of the data catalog or the asset catalog is generated by the catalog generation module, the asset catalog and the data catalog with each other by adding, as an access key, a value that is stored in the first catalog data stored in the data catalog to the second catalog data stored in the asset catalog.

Abstract: An analysis management server stores a factory A catalog group including a plurality of catalogs in factory A, an application destination catalog including a plurality of catalogs in factory B, and an application source analysis data correspondence table associating columns between a target table of factory A and a defect factor analysis table. A CPU is configured to: identify an unconnected catalog for which a catalog of factory B having an identical correspondence does not exist among the plurality of catalogs of factory A included in the application source analysis data correspondence table; identify an unconnected correspondence, which is a correspondence of the unconnected catalog in the application source analysis data correspondence table, sensor data of factory B, and an identical path correspondence which is a correspondence of a catalog on a path including the unconnected catalog; and display information of the unconnected correspondence and the identical path correspondence.
