Ciao is a complete Prolog system subsuming ISO-Prolog with a novel modular design which allows both restricting and extending the language. Ciao extensions currently include feature terms (records), higher-order, functions, constraints, objects, persistent predicates, a good base for distributed execution (agents), and concurrency. Libraries also support WWW programming, sockets, and external interfaces (C, Java, TCL/Tk, relational databases, etc.). An Emacs-based environment, a stand-alone compiler, and a toplevel shell are also provided.
CloverETL is Java-based tool/framework for data integration and creation of data transformations. It is component based and follows the concept of transformation graphs which consist of individual nodes/components performing simple (or complex) operations on data. Any transformation can be defined as a set of interconnected nodes through which data flows. CloverETL can be used as a standalone application or be embedded into a larger project.
CodaServer is a database that makes building business applications easy. It uses a SQL-like language that lets you describe your workflow and business processes, and uses this information to enforce your business rules and guarantee data integrity. It also has a rich set of metadata commands so that your applications can get the information they need to build intelligent, process-aware user interfaces. CodaServer's listener is Web service-based, making it truly cross-platform, and it uses standard SQL databases for storing data, protecting your current investment.
CodeBase is a high-speed xBASE compatible database engine for C/C++, Visual Basic, Delphi & Java programmers. You can use CodeBase to write high performance database applications that are multi-user compatible with FoxPro, dBASE and Clipper, create anything from a Java applet to a full-blown Windows database application to a simple DOS utility, write scalable applications that can be deployed as single-user, multi-user or client/server, all without changing any of your source code, and port your applications to Windows, DOS, UNIX, OS/2, and Macintosh. There's a free 30-Day Test Drive option available. CodeBase is available for every major operating system including Windows XP, 2000, 9x, NT, CE, DOS, OS/2, Macintosh, and a variety of Linux and UNIX platforms including Solaris, SunOS, HP/UX, AIX, SCO, and others.
ColdStore is a gigabyte-scale persistent object store which mmap()s objects into a file (for persistence), can allocate objects in a minimal working-set of pages (for speed), permits library versions to change without a rebuild of the store, permits application checkpoint/restart. ColdStore might be used to replace a database, cache highly structured objects, act as an OODB, make STL persistent, act as a Document Store for XML/SGML/HTML, create a MUD. Future projects include a virtual machine toolkit, ports of several languages, VM and byte-interpretive language workbench.
ConceptBase is a multi-user meta-database system based on a deductive object manager. It is mainly intended for conceptual modeling and coordination in design environments. The system implements O-Telos, a dialect of Telos that amalgamates properties of deductive and object-oriented languages.
Cubulus is an analytic engine and a slice and dice Web interface on top of a relational database (MySQL, PostgreSQL, SQLite, and MonetDB at the moment). It caches calculated cells and is able to parse basic MDX queries, with a maximum of two dimensions cross-join on rows and/or on columns. It includes hierarchical charts: the vertical boxes represent hierarchy "on rows", and horizontal boxes represent data sets "on columns" scaled to the "on rows" measure.
