Abstract

In distributed computing environments, there are many database applications that should share data each other such as data warehousing and data mining with autonomy on local databases. The first step to such applications is the integration of heterogeneous database schema, but there is no accepted common data model for the integration and also are difficulties on the construction of integration program. This paper approaches to automatic elements matching between XML application schemas using similarity measure and relaxation labeling to integrate marine geographic database. For an optimal matching, contextual constraints were used in the relaxation labeling method.
