Alzabo is a two-fold program. Its first function is as a data modelling tool. Through either a schema creation interface or a custom Perl program, it allows a programmer to create a set of schema, table, column, etc. objects that represent a data model. Alzabo is also capable of reverse engineering an existing data model. Its second function is as a RDBMS-to-object mapping system. Once you have created a schema, you can use Alzabo classes to access its data. These classes offer a high-level interface to common operations such as SQL SELECT, INSERT, DELETE, and UPDATE commands.
bigloo-lib is a set of libraries for Bigloo, the Scheme programming language compiler. Most of the libraries are interfaces for various C libraries, such as the C runtime library, Gtk++, the LDAP client API, or the XML parser API. Other libraries are written entirely in pure Scheme, such as the HTTP library and the NODE library. The libraries are intended to make it easier to write programs in Bigloo scheme. bigloo-lib also provides a suitable framework to configure, compile, install, and deploy Bigloo libraries.
Bugzilla is the leading open-source/free software bug tracking system, with high-profile installations at mozilla.org, GNOME, Red Hat, and NASA, among others. It features a comprehensive set of fields, attachment management, inter-bug dependencies, email notification of changes, a powerful query interface, reporting, and Web, XML, email, and console interfaces. It can be managed entirely using a Web-based UI. The user UI is customizable using templates.
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.
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.
The goal of the Database Template Library is to make ODBC recordsets look just like an STL container. As a user, you can move through containers using standard STL iterators, and if you insert(), erase(), or replace() records in the containers, changes can be automatically committed to the database for you. The library's compliance with the STL iterator and container standards means you can plug the abstractions into a wide variety of STL algorithms for data storage, searching, and manipulation. In addition, the C++ reflection mechanism used by the library to bind to database tables allows generic indexing and lookup properties to be added to the containers with no special code required from the enduser. Because the code takes full advantage of the template mechanism, the library adds minimal overhead compared with using raw ODBC calls to access a database.
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.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
