www-sql is able to display information from MySQL or PostgreSQL databases in web pages. It does this with a simple embedded scripting language. The commands are embedded in special HTML tags, so it should be possible to edit the document with an HTML editor. The tags are evaluated when the page is loaded, so the resultant page will be HTML compliant.
The Xitnalta Content Management System (xcms) provides a virtual filesystem library to deal with content from different sources (a real filesystem, a database, etc.) and in different formats. Its goal is to provide yet another way to access and manage data both locally and over the Internet.
xmlizer configurator/server is a client/server approach for custom database to XML mapping. The configurator is used to set up projects and the server delivers the processed requests on demand (like a Web server) according to the mapping rules made with the configurator, which includes a drag and drop GUI. One module is for dumping databases (or parts of it) in a fixed format and the other module can build XML instances satisfying a specified XML Schema (or DTD).
xplain2sql converts files from Xplain to SQL. It supports a very large subset of Xplain, and it can convert from Xplain to Microsoft SQL Server, DB/2, Inprise InterBase, PostgreSQL, Oracle, MySQL 5, SQLite 3 or ANSI-92 SQL. It can also generate an XML description of the generated SQL. This XML description can be used to create low-level middle-tier code. Example stylesheets for Eiffel/ECLI and Delphi/ADO are included. The C source code release should compile on any platform with an ANSI C compiler. There are binary releases for FreeBSD, Linux, Solaris x86, and Windows 2000.
