6. Lab 6, 8 & 15 November - Open a store, collect orders and maintain inventory (how many items are in stock). You will need a rule or trigger, and a function, say, to process an arriving shipment.
7. Lab 7, 22 November - client program to print one order. (select query)
8. Lab 8, 29 November - Look at EXPLAIN of some queries.
   
9. Lab 9, 29 November- Due Friday December 6, that being the "last day of classes.".
     Second client program: To modify your database - May be in C, C++, Python, or PHP
   Write another program to allow a client to enter an order. (insert and/or update statements). Client should identify her or himself, and client (or clerk) see a list of things that can be ordered. Orders to be entered into the database. (or the equivalent). This can be a GUI or web application if you wish.

Notes and Examples

• Fruitstand create table code, class example
• Procedural language examples:
  • A trigger function to guard the bank vault, goblin()
    
  • A function to transfer money, xfer(amount, debit, credit) for the bank concurrency lab, explained
• Frutstand "SuperMario's"
  • SQL definition
  • Terminal interfaces to make an order are on linux.ubishops.ca
    All of them prompt for your name, give a list of fruits and prices, and instruct you on how to order. When asked for a fruit, press enter to finish.
    All programs are named fruitstand.
    Using these languages:
    • C or C++ -- fruitstand.c is source, fruitstand-c is executable.
    • php - you can view the code, or execute it: ./fruitstand.php
    • python - you can view the code, or execute it: ./fruitstand.py
  • Web form is on osiris fruitform.php - see the code
  • ... and receive the order: fruitorder.php - see the code
• XSL stylesheet for XML and a DTD  -- can be embedded in an iframe in HTML
  

PostgreSQL Documentation at www.postgresql.org in particular, SQL Commands

PHP Documentation at www.php.net in particular PostgreSQL

Likewise, documentation for other programming languages can be found on the net, including Perl, Python, and Java

Some Notes and Examples:

• Using php for forms, including databases (a csc103 note) and more details
• Bridal register example.  For the sources, browse to /home/COURSES/CSC207/bridalregister on linux
