PROBLEM TO BE SOLVED: To provide a database retrieval system and a database retrieval method by which users can record information on important know-how without paying a special attention, and can appropriately refer to the information on know-how at search processing. SOLUTION: The database retrieval system for retrieving data in a database, measures the number of times of retrieval condition inputs from the start to the end of retrieval processing or the time required for such inputs, accepts an input of a message describing know-how information in correspondence with contents of the retrieval processing in the case where the measured number of times of the inputs or time required for the inputs exceeds a predetermined threshold value, and stores the message in correspondence with a predetermined retrieval condition during the retrieval processing execution. When executing the retrieval processing, the system compares search conditions inputted by a user with the retrieval conditions stored therein for each acceptance of the retrieval condition. When predetermined numbers or more of the conditions correspond to each other, the system outputs the corresponding message to the user. COPYRIGHT: (C)2005,JPO&NCIPI
