SEQUENTIAL ATTRIBUTE EXTRACTION METHOD FOR RELATIONAL DISTRIBUTE TUPLE DATA OF DATABASE

摘要

The present invention relates to databases, and more particularly to a method for extracting the continuity from the value that is changed in part, for a tuple of a relation which has a continuous nature of relational data in the database. To solve this problem, the present invention is the input of the in the continuous extraction of a dispersed data between tuples in a relation of a relational database, a first step of receiving a tuple domain each value to the input of the distributed data and the distribution data from and a second process and a third process, a value of the continuity of the key domain examining the continuity tuples among tuples domain value is equal with the key domain value having to check the continuity of the key domain value of the tuple, characterized by a tuple domain value yirueojim the same tuple in the fourth process and, in the fifth step of sorting according to a desired form, the extracted continuous data for extracting the continuity of data by the key domain value having the continuity as a new threshold value .
