The time has come to move TPI forward.  After trying Eclipse, .NET, Excel, and Access as user interfaces for a data entry system, I have decided to use Drupal.  Why?

1. No software to install
   The interface is web-based, any computer with a web browser can access it.  Since nothing is installed on the users' computers, nothing ever needs to be updated either.
2. Drupal works with PostgreSQL
   I chose PostgreSQL about 4 years ago to hold battery information.  I do not want to migrate from it to another database, as it has been reliable and easy to adminster.
3. Drupal includes JQuery and JQueryUI
   The features available to a web application are catching up to those of regular desktop applications.  JQuery and JQueryUI provide user interface enhancements like drag-and-drop, and spreadsheets to websites.
4. I use Drupal for other projects outside of work
   I am maintaining two Drupal-based websites, so this will expand my abilities and benefit all three sites.  JohnWoltman.com runs on Drupal.
5. It is free, as in beer
   I don't have to worry about a time-limited demo or paying licensing fees.
6. It is free, as in speech
   I have access to the source code and can see how things work.

Look at the screenshots below for an example of what's going to be possible.  The first is a page listing all the battery models, with the model as a clickable link to more detailed information.  The second is the battery detail page.  I'm looking at including an interactive rate table on this page as well.
