Palm OS Information And Resources Links
Introduction To Palm Os File Formats:
Currently, there are three types of file formats that are commonly referred to in the Palm OS platform:
• Palm database (PDB)
• Palm query application (PQA)
• Palm resource (PRC)
Files with a .pdb or .pqa extension are record databases. Files with a .prc extension are resource databases.
PDB:A PDB is a record database generally used to store data for an application.
PQA:A PQA is a Palm database (PDB) containing world-wide web content. On the Palm device all PQAs are associated through the
Launcher with the Clipper web-clipping viewer. When a user opens a PQA file for viewing, the Launcher starts the Clipper, which in
turn displays the contents of the selected PQA.It is also known and Web Clipping Application.It is a mini website lying on palm device.To build and Test a Palm Query Application You require following tools.you can get palm os emulator and WCA builder from www.palmos.com.
You can download ROM Image which you will require to test Your PQA Application from Here.

PRC:A Palm resource file is fundamentally different from a PDB, but many of the structures are the same. A PRC file contains a resource
list rather than a record list. Palm OS applications are resource databases. A Palm OS application contains code resources as well as
user interface resource elements. In short they are the application similar to .exe program on window machine.
You can easily make palm resource application using C or Java.
If you want to use Java then you can use Waba(www.wabasoft.com) or J2ME for Palm.If you are familiar with
MIDP then you can easily convert your MIDP application to PRC using MIDP for Palm.Links:
