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.
CLIP is a Clipper/XBase compatible compiler with initial support other xBase dialects. It features support for international languages and character sets. It also features OOP, a multiplatform GUI based on GTK/GTKextra, all SIX/Comix features (including hypertext indexing), SQL and ODBC drivers, a C-API for third-party developers, a few wrappers for popular libraries (such as BZIP, GZIP, GD, Crypto, and Fcgi), a multitasking client and application server based on TCP/IP sockets, object data base utilities, and a functions library.
MaVerick is a MultiValue database management system. MultiValue databases are said to be one of the computer industry's best kept secrets. First appearing over 30 years ago as PICK, they have continued to evolve through various commercial vendors, and are still in active development today. They are very resource friendly, are incredibly fast, feature a very user friendly data retrieval and reporting language (variously called ACCESS or English), and a rapid application development language based originally on Dartmouth Basic. The MaVerick project is an attempt to create an open source variant, written in Java.
HotCache is a transactional distributed caching system that runs on top of most RDBMSes. It provides an object-relational mapping tool that makes the use of embedded SQL unnecessary and saves tedious mapping programming. It enhances RDBMS commit functionality by adding commit-broadcast transactions where data is committed to the database and at the same time pushed to all other client caches, in essence keeping the data at remote clients hot. This improves performance by orders of magnitude (as most data access can be done locally) and reduces the load on the database server. The commit-broadcast transactions are implemented using UDP multicast for maximum network utilization. HotCache provides a sophisticated event framework that allows the client to register interest in business objects and be notified when changes are committed. The event framework is built so that it can be easily integrated with other systems' event-loops, eliminating multi-threading problems, etc. Notification can also be configured to take place in an asynchronous/multi-threaded method.
Eleven is a programming language for creating robust, scalable Web applications quickly and easily. It offers a 20x programmer productivity increase over traditional server programming languages like ASP, PHP, and JSP by automating state management and taking control of the application's look and feel. From high-level source code with a simple, C-like syntax, the compiler generates complete, ready-to-run implementations in PHP or mod_perl. Applications maintain their state in a relational database and are inherently fault-tolerant, secure, and scalable.
