摘要： A data management system includes a processor. An estimated ETL level mapping processing unit is operated on the processor to estimate existence of unregistered ETL that is ETL not registered in a repository, to calculate a degree of similarity based on matching between an existing data model and retained data, and to extract a column to be a candidate based on the degree of similarity. The existence of the unregistered ETL is estimated by estimating the presence or absence of connectedness in the ETLs on the basis of correspondence between input data and output data in ETLs by using an execution ETL log relevant to an execution history of the ETL.

摘要： The computer system is connected to a DB that stores data acquired from a production system in which a plurality of machines operate, and includes a generation unit and a data search unit. The DB stores operation data and environment data. The generation unit generates, by analyzing schedule information including a production schedule of the plurality of products, first owner information for storing first access control data including an owner, the machines, and a first access period set based on operation time, and generates, based on the first owner information, second owner information for storing second access control data including the owner, a type of the environment data, and a second access period set based on the first access period. The data search unit controls accesses to the DB based on the first owner information and the second owner information.

摘要： A computer system suited for migration of a virtual server between a plurality of physical servers that do not share a storage apparatus via a network is provided. The present invention is a computer system configured to: couple a plurality of computers together, in each of which a plurality of physical servers and a storage apparatus are directly connected within the same chassis, by directly connecting the storage apparatuses of the plurality of computers: and further have a management computer manage the plurality of computers. When the management computer selects another physical server other than a first physical server in a first computer among the plurality of computers as a migration destination of a virtual server, which operates in the first physical server in the first computer, it judges whether the other physical server exists in the first computer or exists in another computer different from the first computer among the plurality of computers.
