METHOD FOR CONTROLLING CURSOR IN NAVIGATION BASED DATA SET

摘要

PURPOSE: A method for controlling a cursor in a data set based on a navigation is provided to access to a data set by using an object identifier with respect to an object instead of creating an additional storing structure with respect to multiple data set. CONSTITUTION: A basic table is set by analyzing a user's query, and a cursor is constructed by extracting an entry of the basic table and information of an object table(400). An object identifier from the object table is extracted, and the cursor is initialized using the object identifier(402). The user's query is searched in a data set using the constructed and initialized cursor(404). Therefore, unnecessary storing space for the data set obtained by a result of the query in a main internal memory is decreased by providing the cursor providing a sequence access in the data set using the object identifier with respect to multi data set in the main internal memory.
