Abstract
According to an embodiment, a method includes constructing a neutral ontology model of a query front end characterized by ontology schemata which subsume the plurality of different databases on the network in order to provide a common semantic interface for use in generating queries for data from any of the different databases, importing respective database metadata representing logical and physical structures of each database subscribed for receiving queries for data from the database using the query front end, constructing mappings of the database metadata representing the logical and physical structures of each subscribed database to the ontology schemata of the query front end, and storing the constructed mappings for use by the query front end for queries through the common semantic interface of the neutral ontology model for data from any of the different databases.
