Abstract:
1. A method of inferencing semantic data in a relational database system, comprising: (a) creating a new partition in a semantic data table in the relational database system, creating an exchange table and a temporary table in the relational database system, wherein the exchange table has the same structure as the semantic data table; (b) executing on the semantic data table one or more inference rules for a semantic data model; (c) adding into the temporary table any newly inferred semantic data generated by the execution of the inference rules; (d) copying the inferred semantic data in the temporary table into the exchange table; (e) building one or more indexes for the exchange table, wherein the indexes for the exchange table are same as indexes for the semantic data table; and (f) exchanging, by using a processor, the indexed semantic data in the exchange table into the new partition in the semantic data table, in which the indexed semantic data has a format associated with the new partition in the semantic data table that is the same format as a format associated with the semantic data table.
