COMPUTER SYSTEM, METADATA MANAGEMENT METHOD, AND RECORDING MEDIUM

摘要

An object of the invention is to manage correspondence between data having different schemas stored in process servers, data warehouses, or the like in the computer system having a complicated modularity configuration in an integrated manner. The computer system includes a storage portion that maintains schema correspondence information indicating correspondence of metadata described in different schema formats; a storage device that stores metadata in a second schema format different from a first schema format, which is transformed based on the schema correspondence information in a manner of being associated with corresponding actual data and a unified ID; an index portion that acquires the metadata and the unified ID in the second schema format from the storage device and maintains the metadata index transformed in a third schema format different from the first and second schema formats based on the schema correspondence information; and an update managing portion that specifies the unified ID of the metadata to be an update target by using the schema correspondence information in response to an update request of the metadata having a predetermined schema format.
