Aubit 4GL compiler is a programming language based on (and compatible with) Informix-4GL. It provides an easy way to generate screen/form based programs, since statements for handling Windows, Forms, Menus, SQL, and similar are built-in. With support for SQL statements forming an intrinsic part of the language, it's especially suitable for developing database-oriented applications. Database connectivity is provided for PostgreSQL, MySQL, Informix, and others via ODBC. It supports both ncurses (console mode) and GTK+ (GUI mode) output.
The Feature Data Objects API provides a generic, command-based interface to a number of back-end data source technologies for storing, retrieving, updating, and analyzing GIS (Geographic Information System) data. A provider is a specific back-end implementation of the FDO API that provides access to data stored in a particular data source technology.
TinyCOBOL is an effort to bring a free COBOL compiler to Linux. It generates GNU assembler for the i386 Linux platform. A executable binary is then created using the GNU assembler and linker. The project is approaching the first beta release with many statements already implemented.
K.E.T.T.L.E (Kettle ETTL Environment) is a meta- data driven ETL (Extraction, Transformation, Transportation, and Loading) tool. This means that no code has to be written to perform complex data transformations. It is possible to create plugins to do custom transformations or access proprietary data sources. Kettle supports most databases on the market, and has native support for slowly changing dimensions on most database platforms.
The cprops (C prototyping tools) library provides a portable, thread-safe C API including linked list, binary heap, priority queue, hash table, hash list, trie, AVL, Red-Black, and splay tree implementations, a thread pool and thread management framework, a TCP and HTTP socket API, and a database abstraction layer with drivers for Postgres and MySQL. libcprops compiles and runs on Linux, BSD, Solaris, Mac OS X, and Win32.
Schevo is a next-generation DBMS that focuses on database integrity, rapid development, user interface generation, rich schema definition, and assisted schema evolution. Schevo was designed to address shortcomings in SQL-based relational databases where they do not match well with object-oriented programming languages. Schevo solves this problem by combining relational features with the object-oriented programming language Python. Schevo includes a GUI Navigator that can display a fully interactive interface into any Schevo database, using the metadata available within a Schevo database file.
