Abstract: A computer network uses first and second computers to host first and second websites. Customer data is accumulated at the first website. The customer data is stored in a database. The first website creates a reference number from a customer identification number and reservation number to identify a location of the customer data in the database. The customer selects a hyperlink from the first website to the second website. The reference number is sent to the second website in the URL address string. The second website uses the reference number to retrieve the customer data stored in the database and populates the second website. The second website provides information and recommendations generated from a suggestive analysis of the customer data for the benefit of the customer.
