4Suite is a Python-based toolkit for XML and RDF application development. It features a library of integrated tools for XML processing, implementing open technologies such as DOM, RDF, XSLT, XInclude, XPointer, XLink, XPath, XUpdate, RELAX NG, and XML/SGML Catalogs. Layered upon this is an XML and RDF data repository and server, which supports multiple methods of data access, query, indexing, transformation, rich linking, and rule processing, and provides the data infrastructure of a full database system, including transactions, concurrency, access control, and management tools. It also supports HTTP, RPC, SOAP, and FTP, plus APIs in Python and XSLT.
DBPrism is an open source framework to generate dynamic XML from a database. It connects Oracle databases with Apache Cocoon, providing a high performance DBGenerator with functionality such as parallel content aggregation and ESI cache protocol. It also includes a powerlful database oriented CMS built on top of Apache Cocoon2 and DBPrism.
Xindice is an open source Native XML Database. It stores and indexes compressed XML documents in order to provide that data to a client application with very little server-side processing overhead. It also provides functionality that is unique to XML data, which can't easily be reproduced by relational databases.
Expresso Framework is an open standards-based J2EE architectural framework that allows the developer to concentrate on application logic. It is a library of extensible Java Server application framework components for creating database-driven Web applications based on open standards. Expresso integrates with Apache Jakarta Struts, which emphasizes presentation and application configuration, and bringing a powerful tag library to Expresso. Expresso adds capabilities for security, robust object-relational mapping, background job handling and scheduling, self-tests, logging integration, automated table manipulation, database connection pooling, email connectivity, event notification, error handling, caching, internationalization, XML automation, testing, registration objects, configuration management, workflow, automatic database maintenance, and a JSP tag library.
The JGenerator is a Web server production application that can dynamically combine text, graphics, and sound to build rich Flash content. It is a free alternative to and analog of Macromedia Generator. It supports most of the Macromedia Generator features, uses the same data format and the same set of commands, and emulates its behavior.
Velocity is a Java-based template engine. It permits anyone to use the simple yet powerful template language to reference objects defined in Java code. When Velocity is used for Web development, Web designers can work in parallel with Java programmers to develop Web sites according to the Model-View-Controller (MVC) model, meaning that Web page designers can focus solely on creating a site that looks good, and programmers can focus solely on writing top-notch code. Velocity separates Java code from the Web pages, making the web site more maintainable over the long run and providing a viable alternative to Java Server Pages (JSPs) or PHP. Velocity also provides template services for the Turbine Web application framework, making a template service that allows Web applications to be developed according to a true MVC model.
X2c is an Xbase compiler that creates executable programs from Xbase source on any Unix or C platform. This is accomplished by creating C source from the Xbase source, compiling, and linking with included Xbase function libraries. Whilst the C source is considered an intermediate stage for X2c, it can be used and developed as any other C source. The X2c dialect of Xbase accepts virtually all statements from Borland (was Ashton-Tate), dBASE III PLUS, Computer Associates (was Nantucket), Clipper (Summer '87), and Microsoft (was Fox Software) FoxBASE (2.1). Selected Foxpro statements are also supported.
Cameleon a Framework for developing reliable database applications in a technology independent and predominantly editorial way. User interfaces may be easily exchanged from Swing to HTML and vice versa, and databases may be exchanged in the same manner. The Swing variant framework is established. The HTML user interface is under construction but can be reviewed on the project Webpage ("Test sample application"). Cameleon's target users are programmers who manage midrange data volumes (from thousands to millions of database records) and who prefer simplicity and availability rather than animation. Business features such as security management and parameter administration are supported in the framework. The framework allows web developement without any knowledge of JSP, HTML, Servlets etc. Data input elements (and groups of them) may be used in Java Server Pages.
mod_log_sql (formerly known as mod_log_mysql) is an Apache module that enables access logging to an SQL database. This capability can replace or coexist with Apache's regular text-file logging mechanisms. The currently supported database backend is MySQL, with PostgreSQL and others in development.
