Embodiment Construction

[0013] Such as figure 1 Shown is the hardware architecture diagram of the fuzzy query system of the present invention. The system includes multiple client computers 10 , a network 11 , a query server 12 and a database 13 . The client computer 10 and the database 13 are respectively connected to the query server 12 through the network 11. The network 11 may be an intranet of an enterprise, or may be the Internet or other types of communication networks. The client computer 10 is used to set query conditions and query fields. The query server 12 is used to execute the fuzzy query job according to the query conditions set by the user, and return the query result to the user. Database 13 is stored with preset synonym group, and this synonym group is the synonym group preset by the database manager, and the user can not amend at will, and a group of words with the same or similar meanings are organized into a form and stored in the database in advance by the database manager mid...

Abstract

The system includes multiple computers at client ends, a query server and a database. The query server includes a conditional setup module, an implementing query module and a module for outputting queried result. User through computer at client end sets up whether to carry out blur query or not and condition of carrying out blur query. Based on setting, implementing query module queries patent data accorded with blur condition from a database automatically, and queried result in graphic mode is output to computers at client ends. The method includes following procedures: selecting blur query, setting up query fields, inputting key words, generating query program through query program at background, executing blur query and generating query result. The said query result through computer at client end is outputted to user.

Description

【Technical field】 [0001] The invention relates to a query system and method, in particular to a system and method for performing fuzzy query in a database. 【Background technique】 [0002] With the advent of the information age, users store a large amount of information in the database and use the database management system to perform information integration and management, and obtain the required information by querying the database. Existing database query methods often emphasize how to perform retrieval of relevant information more effectively, that is, perform exact matching on query keywords input by users, so that the information that users can query is relatively small. [0003] The application number disclosed by the State Intellectual Property Office of China on January 6, 1999 is the patent application case of 98116377.7, and its title is "the fuzzy input query processing method of the database". The application discloses a processing method for querying a database...
