An XQuery and XPath 2.0 library, written in C++ and built on top of Xerces-C.

DBIx::MyParse is a Perl module that makes the MySQL SQL parser engine available to Perl applications.

JoSQL (Java Objects SQL) provides SQL capabilities for querying, ordering and grouping of collections of Java objects (POJOs). It allows a SQL statement to be applied to the collection of objects and the matching set returned, ordered and grouped.

Wrapper library for adding MySQL support into the REXX language. Libraries are written in C and then imported into REXX scripts. Once imported REXX scripts can access most of the functions of the MySQL C API through REXX.

Basilisk is an embeddable data engine and virtual machine. Applications may use it to allow data and logic to be stored externally in a format that users may read and modify.

Cigol (logic, spelled backwards) is a deductive logic solver. It can be embedded inside a parent program or used from the command line. It has absolutely no relationship to Tom Mitchell's book on Machine Learning.

dlvhex is a prototype solver for HEX-programs which integrate Answer-Set Programs with higher-order reasoning and external computation sources. It comes with a full-fledged plug-in framework for rapid extension development.

DataLoggin provides the raw data Database for the Dawn of Light Server Emulation Project. (www.dolserver.com)

DSQL ("Dynamic" SQL) is a scripting language for SQL, aka Perl for JDBC. It allows rapid development of code to perform database programming, data warehousing and import/export from databases, XML, Excel, etc.

DWI (recently renamed to Estron and moved to http://estron.alioth.debian.org/) is a rapid application development system for creating graphical applications that manipulate info in an SQL database. Uses XML and Gnome Glade for the GUI designer.

From the XML definition of your database, DewDrop will generate clean and human-readable SQL DDL code for any supported target database. This means you can define your database just once in XML, and have it work for any database automatically.

A relational database management system, based on the principles laid down in the book "Databases, Types, and The Relational Model: The Third Manifesto" by C. J. Date and Hugh Darwen.

ErgoTabcalc is a general calculation and report system. Calculation sequences are stored in the database. These sequences are made from simple operations on data, eg, add two table columns, or sort a table. This is similar to relational algebra.

Extensible Data Objects (EDO) is a Markup-style scripting language for accessing and manipulating data from different sources (predominantly SQL sources, but also capable of extending to DNS, etc...), through an extensible plugin framework.

FOML is an expressive logic rule language that supports object modeling, analysis, and inference. It naturally supports model-level activities, such as constraints (extending UML diagrams), dynamic compositional modeling, analysis and reasoning about models, model testing, design pattern modeling, specification of Domain Specific Modeling Languages, and meta-modeling. FOML can reason about: 1. The model meta-data (meta-model level reasoning, or syntax reasoning) 2. Data level: reason about a model and its data (instance model, i.e., diagram) FOML is built as a semantic layer on top of PathLP - a compact logic rule language of guarded path expressions, an adaptation of a subset of F-logic.

FramerD is a distributed semi-structured object database originally developed at MIT. It provides an internationalized Scheme-based scripting language, built-in text analysis tools, and special support for web scripting.

The Generic Universal MUMPS Project (GUMP) has the purpose of providing an Open Source Implementation of ANSI X11 (MUMPS) suite of Standards

A simple interface to SQL databases (currently MySQL and PostgreSQL) from Guile.

A tool to query arrays in memory using SQL. It groups the arrays in tables and returns arrays as result set. It can be used in spreadsheets, as a script language library and everywhere is needed an interactive tool to query data in memory.

JudoScript is a general-purpose, Java scripting, multi-domain scripting tool/language. It combines the powers of declarative scripting for many modern tasks and general object/procedural programming. It is simple, intuitive, practical and powerful.

An XML-based MP3R framework for the web applications Model - Process - 3R (Role, oRgnization, Responsibility)

Development tool for database based application creation.

The Open Design and Integration Environment is a toolbox of C and TCL code designed to introduce people to programming in a friendly way. It is also designed to be robust enough to novices to develop useful applications.
