IBM OpenDX, the successor to IBM Visualization Data Explorer, (known simply as DX) is a general-purpose software package for data visualization and analysis. It employs a data-flow driven client-server execution model and provides a graphical program editor that allows the user to create a visualization using a point and click interface. Applications can also be built on top of portions of the Data Explorer system, so that custom, turnkey applications can be easily developed using DX as the computational and rendering engine.
The HTML::Template module attempts to make using HTML templates simple and natural. It extends standard HTML with a few new tags for variables, loops, if/else blocks and includes. A file written with HTML and these new tags is called a template. Using this module you fill in the values for the variables and loops declared in the template. This allows you to seperate design (the HTML) from the data, which you generate in the Perl script. While there are many other HTML template systems available, this module is simple and fast. It doesn't try to reinvent Perl CGI, it just augments HTML with a few new and very useful abilities.
Websqlbrowse is a web-based SQL database browser. Browses may be restricted and customized, and records may be added, edited, or deleted. Websqlbrowse currently works only with MySQL. While it is not currently in active development, it's still a fast, lightweight DB interface that is fairly easy to set up and is currently in use by quite a few people around the globe.
The Faq-O-Matic is a CGI-based system that automates the process of maintaining a FAQ (or Frequently Asked Questions list). It allows visitors to your FAQ to take part in keeping it up-to-date. A permission system also makes it useful as a help-desk application, bug-tracking database, or documentation system.
When building server side applications for the Web, independently of the language used (Java, PHP, Perl, etc), a lot of time is spent writing embedded HTML code and dealing with the fact that HTTP is a stateless protocol. SPFC allows you to write HTML forms like you write a Java GUI.
Midgard is a persistent storage framework. It provides an object-oriented and replicated environment for building data-intensive applications. It ships with a MidCOM content management system built on the Midgard framework. MidCOM's features include Web-based authoring WYSIWYG interfaces and a component interface for installing additional Web functionality. Midgard is built on the GNOME stack of libraries like GLib and libgda, and has language bindings for C, Python, and PHP. Communications between applications written in the different languages happen over D-Bus. The CMS runs on the LAMP (Linux, Apache, MySQL and PHP) platform.
tree.pl creates a sitemap for all kinds of files (e.g., HTML and image files). It follows the directory structure on disk, creating a nested HTML list that contains the files' names or (in case of HTML) their titles, their last modified date, and their size. tree.pl can be used as a normal commandline application or as a CGI script.
