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.
Data-Admin is two separate components. The first being Data-Lib, the underlying encapsulated database library. This library wraps PHPs native database functions to provide a unified method for connecting to a database. The second component is Data-Admin which will be a PHP based front-end for basic database administration.
GQL is a C++ library for generic SQL database access, modeled after JDBC (Java Database Connectivity). It includes drivers for PostgreSQL, MySQL, and SQLite, and includes GQL-Shell, an interactive database terminal called that features command-line editing, history, and database metadata (schema) browsing.
iODBC is a cross-platform Driver Manager that comforms to the Microsoft ODBC 2.x & 3.x and X/Open SQL CLI data access specs. It enables the development of database-centric solutions that are both database and platform independent. This is a great SDK for porting WIN32-based ODBC applications to Linux and other OS platforms.
The Information System Development Kit gives the developer a platform-independent method of creating Information Systems with data forms, SQL database access, database-browsing support, report generator and many other useful features. ISDK is now in a development stage and it is available only for the Linux operating system. The form module now works on text terminals using the ncurses library (not functional right now), and on the X-Window system using the GTK+ toolkit.
