BibTeXConv: BibTeXConv is a BibTeX file converter which allows to export BibTeX entries to other formats, including customly defined text output. Furthermore, it provides the possibility to check URLs (including MD5, size and MIME type computations) and to verify ISBN and ISSN numbers.

Bibfilex: Bibfilex is a bibliographic manager. It's useful for creating and managing archives of bibliographical items (books, articles, etc.) with possible attachments of any kind according to Biblatex structure and rules, but it can be used also with a word processor like Writer or Word. Bibfilex may create and manage files which are catalogs of many items – also thousands of them. A file of Bibfilex is a database of SQLite. In a Bibfilex file data are not stored according to Biblatex format, so it cannot be used as a bibliographic file in a Latex document. Anyway, Biblatex may export with a one-click functionality all or part of its content in Biblatex format file; this can be read directly with JabRef or used in a Latex document. At the same time, Bibfilex may import directly a JabRef database.

Bond: BOND (building object network databases) is a rapid application development tool which allows you to develop GUI front ends to PostgreSQL databases. It uses XML to define widget layout and how to obtain information from databases. This project is designed to simplify the process of developing database applications for GTK.

Bonddb: 'bonddb' is an object orientated wrapper for PostgreSQL. It's a fast data abstraction layer C/C++ applications, to allow easy access to class objects. You can use existing PostgreSQL databases without any modification or additional tables needed in the backend. "bonddb' easily modifies rows in database fields without you having to construct sql statements or worry about refreshing existing datasets. It also lets you easily map your tables together in object to object relationships. Method calls aren't supported yet but they are being worked on.

CrocoPat: 'CrocoPat' is a tool for querying and manipulating relations. It is easy to use because of its simple query and manipulation language based on predicate calculus and its simple file format for relations. It is efficient because it internally represents relations as binary decision diagrams, a data structure that is well-known as a compact representation of large relations. CrocoPat is general, because it manipulates not only graphs (i.e. binary relations), but n-ary relations.

CsvCat: Read multiple comma separated value files, such as exported from a spreadsheet or a database, and combine the output into a single file. Options are available to limit the columns included and to semi-intelligently skip headers.

CsvUtils: Transformation utilities for csv (or csv-like) generated rows. The standard csv module is very useful for parsing tabular data in CSV format. Typically though, one or more transformations need to be applied to the generated rows before being ready to be used; for instance "convert the 3rd column to int, the 5th to float and ignore all the rest". This module provides an easy way to specify such transformations upfront instead of coding them every time by hand. Two classes are currently available, SequenceTransformer and MappingTransformer, that represent each row as a list (like csv.reader) or dict (like csv.DictReader), respectively.

DBIx Simple: DBIx::Simple provides a simplified interface to DBI, Perl's powerful database module. It is aimed at rapid development and easy maintenance, but not at SQL abstraction

DBLIB: DBLIB is a PHP library to create WWW interfaces to databases. Its main aim is to support creating interfaces for site administrators, but it can be used as well to create public end-user interfaces. It features over 15 widget types (text, numbers, datetime, password, reference to another table, etc.), automatic data conversion and escaping, automatic input checking in all fields, an abstract data layer that supports several SQL databases, LDAP, and text/dbm files. DBLIB is not a low-level database manager like PHPMyAdmin.

DataStatix: DataStatix is a free software for GNU/Linux and Windows useful to manage data of every kind (although it has been written to manage biomedical data), to create descriptive statistics and graphs and to export items easily to R environment or to other statistic softwares. In order to handle properly big amount of data and many concurrent users, DataStatix works with MySql database and it has been developed and tested with MySql community edition 5.5. Some features of the software are: users management (create, delete, modify password) within the software; different users levels of data access (administrator, default, read only); user defined templates (models) of data, to create new databases easily; importation and esportation of data in CSV format (used also by Calc and Excel); updating of existing data from a CSV file created with DataStatix; descriptive statistics from every data (some more kind of statistics to come); graphs from every data.
