Some of its features include: - Tck/Tk programming interface - Portable database format - Easy to use, you can have a DB application completely up and running in about 5 minutes, using nxqddb. - CGI interface for quick and easy online databases/guestbooks/etc... - Fast, and powerful searching capability - Report generator - Barcharts and graphs - Mass mailings with Email, letters and/or postcards - Lots of prepackaged applications are available - Much, much more... Qddb is a database suite that allows you to create relations, add tuples, modify tuples, delete tuples, and search for tuples in a fast and very flexible way. Qddb revolves around the idea of a "tuple tree," where tuples are stored and manipulated in an intuitive, pre-joined way. Qddb supports the following search techniques: regular expressions, words and word ranges, numbers and numeric ranges, and dates and date ranges. Approximate matching is coming soon. Qddb can use Tcl as its configuration language, so you can build custom interfaces to your Qddb databases with it. We provide a reasonably nice generic interface so you can be up and running quickly.
