We present an evidential scheme for integrating semantically heterogeneous aggregates, stored as summary tables, of distributed databases. The ontology of discourse at which to carry out the integration of aggregates is the common ontology derived from local ontologies in the form of classification schemes. The distributed aggregation combination operator DAggCom is developed to combine aggregates from local databases and requires minimal communication with local data sources.
