Abstract
A newly defined data type is added to a database management system. Information about a query component assisting in querying data belonging to the newly defined data type is registered along with data type information in a query component information. If the data type being queried is the newly added data type, the query component information is searched to find a query component for assisting queries to data belonging to the particular data type. The matching query component is activated and a screen is displayed to input information needed to query data belonging to the data type. The information is input and a query statement is generated using the inputted information. The generated query statement is issued to the database management system and query results are obtained.
