SQL Query Construction from Ontology Concept Descriptions

Based on the usage of previously proposed database concepts as mapping point to a database in a domain ontology, the present paper describes the process of constructing SQL queries from them. The proposed database concepts allow for the mapping of domain concept to the source of data from a database. The paper describes the process of traversing the class hierarchy in an ontology for gathering these database concepts and constructing the SQL query. The purpose of the constructed SQL query is to obtain data from a database to populate the ontology with instances related to a selected ontology concept. The described process begins with the selection of one ontology concept, obtaining all directly related concepts, filtering and collecting database concepts, and finally constructing the SQL query
