91.308 Assignment 10:
Palm OS Database Programming

out: Wed May 4 ——— due: Wed May 11

In this assignment, you will extend the Librarian sample application provided in the Lonnon Foster text.

This application demonstrates how to use the Palm's persistent database storage technology, and the Palm's Global Find operation.

As Before...

  • You may choose to work on this assignment on your own machine and/or in the Engaging Computing Lab (OS306). If you want to do all the work on your own, that's fine—you can test your work with the Palm emulator software.

  • If you want to see your work running on a real Palm handheld, then plan to do some work in OS306. There will be 8 machines set up with Palms and cradles.

  • All 91.308 students have been given 24x7 access to OS306 via your ID card and the electronic door pad.

Assignment Details

  1. If you haven't already set up your Palm dev environment, see Assignment 9.

  2. Obtain the Librarian application sample code at www.cs.uml.edu/~fredm/308/files/popb_librarian.zip.

  3. Read the excerpt from the Lonnon Foster book that was handed out in class. This explains the Librarian application.

  4. Compile and build Librarian. Get it running on either a Palm emulator or a physical device. Note: If your development tools are running on a Unix system, you may have to remove the MS-DOS CTRL-M line terminations from the file librarianDB.c.

  5. Change the application's creator code to some other 4-character value (not all lower-case, since those combinations are reserved by Palm).

  6. Now, modify it:

    • Add at least two new fields to the application. Update the forms to allow you to enter data into these new fields, and update the database code to save the data from these new fields into the persistent storage.

    • Make sure that you extend the Global Find code to search through your new fields. In your writeup, turn in a screen snapshot that shows that the Palm is able to find data stored in your new fields.

  7. Turn in your work. Include:

    • (a) zip or tar your source and your .prc application file into a single archive and put it in a reachable location on your CS account,

    • (b) print out diff's between the original code and your changes,

    • (c) print out the screen snapshot showing Global Find in action retrieving data from your new fields, and

    • (d) submit a hard copy cover sheet that gives a directory pointer to your work and explains in some detail what you did,
