WebQA tries to be a multi-user relational Web database that can be used without reading documentation. The user can create forms with input fields and fill these record cards with data. The record cards can be browsed, and lists can be produced from the data. The backend is a virtual database structure built with MySQL.
xdata implements an interface to arbitrary key-value pairs which are accessible to simple shell and Perl programs. Applications for this include to-do lists, contact databases, browser bookmarks, and anything else which requires small pieces of data to be referenced by keys. xdata stores timestamps for the data it manages, and comes with a program to synchronise databases among cooperating hosts. This allows you to propagate information among hosts in a transparent fashion (creations, updates, and deletes are correctly handled). xdata consists of a set of shell-level utilities and a Perl module.
