Questions
Identify an Internet site that has a very effective Query-by-Example (QBE) implementation for complex queries (queries made up of multiple attributes/fields, simultaneously executed) to efficiently navigate among the database (as described in the publisher's Chapters 2 and 9 of a previous edition of our text.
QBE is more than just a single word/single phrase search capability found in some web site's so-called "advanced search" or one field product selection sites in that it is a graphical user interface based query synthesis capability involving many of the database's attributes/fields simultaneously.
Please re-read this to keep from selecting a search site that is not QBE by our definition (be careful in searching the web on this as there are a few bogus [erroneous] definitions of QBE out there - don't get confused on this). Provide the complete URL as a reference so we may all experience it.
Tell us why is this QBE implementation is so effective (what appeals to you about its use)? In addition to the above, to get full credit for your submission, your QBE site must be publicly accessible so that the rest of the class and I can experience the site.
