DATA INTEGRATION DEVICE, METHOD, AND RECORDING MEDIUM CONTAINING PROGRAM

摘要

When data existing in a plurality of information sources (103) managed separately are collected and integrated, data collection from the information sources (103) is performed by a data model (physical model (111)) of each information source side and the integration process is realized by a process (mapping) for converting data structure for a data model (logical model (112)) defined in advance for each of user side applications (104) and providing the result as a view (logical model (112)) for each of the applications to the user side applications.
