Introduction

The project for this chapter is a database of information on web sites. Registered users—we'll call them finders—may add sites to the database, the site information consisting of the address (URL), along with a name, category, and description contributed by the finder. Finders are registered with IDs and passwords, presumably by a system administrator. A registered finder can change his or her password. Anyone can view the whole list of sites, or, by clicking a drop-down list generated dynamically to be a list of unique categories in the database, view the sites in a selected category. Finders can delete sites from the list.
