OBJECT-ORIENTED SOFTWARE COMPONENT EXTRACTION SUPPORTING AND RETRIEVAL DEVICE

PROBLEM TO BE SOLVED: To provide an object-oriented software component extraction supporting and retrieval device for supporting the efficient extraction and storage of an object-oriented software component from an existing class diagram in an object-oriented software component retrieval device for performing retrieval by an application field and an appearing frequency. SOLUTION: This device is provided with a class structure component extraction condition input means 2 for receiving a relation number in extracting a class structure component as input, a class structure component extraction means 5 for extracting the candidates of the component from the existing class diagram, a pattern classification means 8 for classifying the class structure component as a pattern from the structure of the class diagram, an each pattern class structure component number calculation means 11 for calculating the using frequency of the component for each pattern, an each pattern class structure component number display means 12 for displaying the result, a pattern application field retrieval means 14 for retrieving the application field of the component for each pattern and a pattern application field display means 13 which is the input/output means.
