KEYWORD RETRIEVING SYSTEM FOR DATA BASE

摘要

PURPOSE: To simplify a describing method and to easily perform setting even in the case of a complicated retrieval expression by inputting a desired keyword to a keyword input area, linking it with another card as needed and deciding a search condition. ;CONSTITUTION: A keyboard inputs the keyword to an area 18 of a card 16 displayed as a window. When there is any keyword to be further inputted and the retrieval condition is 'AND', the keyword is inputted to an area 20 or when the retrieval condition is 'OR', it is inputted to an area 22. Concerning the other card, the keyword is similarly set as well, and a series of retrieval expressions can be set by linking these cards on the inter-card retrieval condition.;COPYRIGHT: (C)1993,JPO&Japio
