Abstract
A Database Management System (DBMS)-based Semantic Web query system and method using parameterized SPARQL queries are provided. The present invention is configured to include output means that creates a parameter list from a SPARQL query statement, converts the query statement into an SQL statement and stores a PREPARED STATEMENT (PS) object in association with the SQL statement, thereby outputting query results. Accordingly, the query time of a Semantic Web service can be reduced, thereby improving QoS.
Claims42
A Database Management System (DBMS)-based Semantic Web query system using parameterized SPARQL queries, comprising:
- parameter list creation means for creating a parameter list from a SPARQL query statement;
- conversion means for converting the SPARQL query statement into an SQL statement;
- storage means for storing respective Prepared Statement (PS) objects in association with one or more SQL statements;
- and
- a DBMS for outputting query results using a PS object stored in association with the resulting SQL statement and the previously created parameter list.
A DBMS-based Semantic Web query method using parameterized SPARQL queries, comprising:
- a parameter list creation step of creating a parameter list from a SPARQL query statement;
- a conversion step of converting the SPARQL query statement into an SQL statement;
- and
- a query result output step of a DBMS outputting query results using a PS object stored in association with the resulting SQL statement and the previous created parameter list.
