Specifications

We’ll build a module for each box on this diagram—some will need one script and others,
two. We’ll also set up function libraries for
• User authentication.
• Bookmark storage and retrieval.
• Data validation.
• Database connections.
• Output to the browser. We’ll confine all the HTML production to this function library,
ensuring that visual presentation is consistent throughout the site. (This is the function
API approach to separating logic and content.).
We’ll also need to build a back-end database for the system.
We’ll go through the solution in some detail, but all of the code for this application can be
found on the CD-ROM in the chapter24 directory. A summary of included files is shown in
Table 24.1.
