TY - JOUR ID - 405169 AU - Kohoutková, Jana PY - 2002 TI - Meta-Level Transformations in Systems Integration PB - Slovak University of Technology in Bratislava CY - Bratislava SN - 8022717444 KW - heterogeneous information systems KW - integration KW - interoperability KW - data modelling KW - graph representation N2 - The paper provides a brief overview of the HyperMeData language specifically designed to support data interchange among heterogeneous information systems, and pays attention to meta-level transformation descriptions. The language is sufficiently complex and powerful to catch both intra- and inter- data schema relationships (i.e., to describe both data schemas and data transformations), nonetheless, its routine use requires employing a set of meta-level transformation rules to handle typical schematic differences among semantically similar database objects. The classification of schematic heterogeneities in multidatabases is used as the basis for proposing inter-attribute correspondences (meta-level transformation rules) and the respective translations to HyperMeData descriptions of data transformations (transformation rules).
