Tdbengine is an RDBMS with an integrated programming language. It represents the enhancement of the famous DOS-TDB, and is designed to handle databases on the Web. It connects to the Web server using the standard CGI interface, or runs on the command line. It is very small (about 400 KBytes), extremely quick, and easy to administrate. Its features are full text indexing, an automatic data link system, and the script language EASY, which replaces the commonly used SQL with its modular code.
tdbSQL is a complete implementation of an EASY SQL server for the tdbengine RDBMS. It is a client-server solution that can be accessed via TCP and makes it possible to access tdbengine DBs from languages other than EASY, including Perl, PHP, C, C++, C#, and Java. It combines the perfomance of the tdbengine with the feeling and standards of other SQL databases and features integrated rights management.
The EASY pdflib provides a set of functions and procedures which allow an easy generation of PDF files from within tdbengine-based Web applications. It generates Adobe Acrobat Reader compliant output. There are common functions for drawing simple texts, tables, or graphics, as well as table access functions to directly output database contents.
Bug-A-Boo is a bug reporting and tracking system that runs on any Web server that supports CGI. It helps you to keep an eye on bugs reported to you by users of your software products. It can handle any number of projects, users, and bug classifications, and is really flexible in their setup. It features fast fulltext search, query storage, themes, and bug watches. It uses the tdbengine as a database backend.
IMAPEngine is an IMAP server that uses a tdbengine database structure to store all accounts, messages, and mailboxes. This means it has nearly no limits in numbers, sizes, and performance, and it uses indexes to sort/find its data. IMAPEngine is IMAP4Rev1 compatible and also has built-in support for the ACL, ID, IDLE, and UIDPLUS extensions. It is not (yet) an MTA, but it retrieves incoming messages from different POP3 servers. An simple integrated Web interface makes account configuration easy.
GeboGebo is a wiki system written for tdbengine. It stores all data in a local database structure and thus provides an indexed fulltext search. It uses a simple syntax, and has user lists, pages history, a missing pages list, and a recent changes list. Image and file upload are possible, but can be disabled. This allows it to work as a small document management system. A blacklist allows you to lock existing pages from being edited or new pages from being created. It can also be run in static mode, where all pages are additionally held as static HTML pages.

Another possible non-SQL rdbms for linux (and windows) can be found here :
http://www.tdbengine.org (http://www.tdbengine.org target=_blank)
It's a freeware/open source rdbms which is very compact, has a big feature list and of course is not queried by using sql. It has its own script language.
