System and method for POS based fuzzy theory utilizing data extraction

摘要

In order to facilitate a customer's non-specific enquiry relating to sales records accumulated by a POS system, the sales records are utilized to form a plurality of data tables in response to the customer's non- specific enquiry. The data tables thus obtained are multiplied to produce at least one fuzzy membership function. The function is used to isolate data in an inventory data base pertinent to the non-specific enquiry.
