4store: 4store is a database storage and query engine that holds RDF data. 4store's main strengths are its performance, scalability and stability. It does not provide many features over and above RDF storage and SPARQL queries, but if your are looking for a scalable, secure, fast and efficient RDF store, then 4store should be on your shortlist.

ADL: Database load balancing class for PHP applications who need to deal with various MySQL servers. The class will properly detect write queries and will try the next available server(s) until running out of connections. Multi server connection handling in progress in order to allow running transactions in many servers at the same time.

ADOdb is a database abstraction library for PHP. The PHP version currently supports an amazing number of databases, thanks to the wonderful ADOdb community: MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Foxpro, Access, ADO, Sybase, FrontBase, DB2, SAP DB, SQLite, Netezza, LDAP, and generic ODBC, ODBTP. The Sybase, Informix, FrontBase and PostgreSQL, Netezza, LDAP, ODBTP drivers are community contributions. Some reasons why ADOdb is popular include:

Designed for speed. It is probably the fastest free software database abstraction library available for PHP. See benchmarks.
Provides extensive portability support such as date and type-handling and portable schema creation. See portable sql tips
Support many enterprise features such as database backed sessions (with session expiry notification), SQL code generation, pivot tables, SELECT LIMIT emulation for all databases, performance monitoring.
Easy to learn.
Extensive QA, every release is unit-tested on Access, MySQL, PostgreSQL, MS SQL, Oracle 9.
Mature, continuously developed since August 2000. Has a large community of users.
Powerful Active Record support. See docs.
Very reasonable licensing terms (BSD). This means that you can incorporate (and even compile) it into your software applications royalty-free without asking the author's permission, provided you include license.txt in your release.

ADOdb Lite: A small, fast replacement for ADODB that uses 1/6th of the memory and upto 300% faster while being compatible with ADODB using a subset of the most often used ADODB commands.. Supports Frontbase, MaxDB, MiniSql, MSSQL, MySql, Postgres, SqLite and Sybase.

ADOdb for Python

ADOdb is a database abstraction library. ADOdb was originally developed for PHP, and ported to Python. The Python version implements a subset of the PHP version. You might ask why Python needs a database abstraction library when Python provides the official DB API. Unfortunately the DB API does not encapsulate differences in the database implementations. For example, to select a limited number of rows, say 10 rows, you would have to use very different SQL for different databases:

MS SQL select top 10 from table
MySQL and PostgreSQL select * from table limit 10
Oracle select * from (select * from table) where rownum <= 10
These differences are handled by ADOdb (using SelectLimit), but not by the Python DB API. Other important database differences transparently handled by ADOdb include date-formating, associative arrays (records as dictionaries) and LOB-handling.

AWStats: Advanced Web Statistics is a free tool that generates advanced web server access statistics graphically. This web server log analyzer works as a CGI or from command line and shows you all information your log contains, in few graphical web pages. It can analyze IIS 5.0+, Apache log files and some other web servers (log files with a personalized format are supported since version 3.0). It's the best statistics tool for web server with less than 200,000 visits a month. The program can measure visits, unique vistors, pages, domains/countries, OS busiest times, robot visits, search engine/keyword used, and HTTP errors. Statistics can be updated from a browser or your scheduler. The program also supports virtual servers.

Academic Teaching Planner: Academic Teaching Planner is a free software useful to plan university courses and various types of tests. It is designed as a personal tool beside management software used by academic institutions, and allows to: 1. manage and archive the documentation of each single course (objectives, bibliography, dates, information texts, lessons, files of all kinds, etc.) as well as the results of the tests, even the intermediate ones that are not always stored in management systems used by academic institutions; 2. manage the list of students who are enrolled in each individual course, easily retrieving their data from the management system in use at the academic institution, and their tests; 3. compare the distribution of bibliographic resources in the various lessons, made by the professor, with a reference model obtained by their homogeneous distribution throughout the course, to verify, also with the aid of diagrams, that the supposed planning is substantially realistic, that is, can be completed on schedule without omitting topics or lessons in excess. Academic Teaching Planner is a cross-platform software that runs natively on GNU/Linux, Windows and macOS. It manages data with Sqlite, a well-known and reliable database, while saving attachments (i.e. files of any kind associated with the various sections of the software) in an external folder, in a transparent way for the user. Their number and size are limited only by the space available on the computer in use. Academic Teaching Planner has been written with Lazarus (www.lazarus-ide.org) and uses the Sqlite database through the Zeos components (sourceforge.net/projects/zeoslib).

Aletheia: In short, Aletheia is software for getting science published and into the hands of everyone, for free. It's a decentralised and distributed database used as a publishing platform for scientific research. So, Aletheia is software. But software without people is nothing. To comprehensively answer the question what is Aletheia, Aletheia is software surrounded by a community of people who want to change the world through open access to scientific knowledge. For a more in depth explanation, Aletheia is an Ethereum Blockchain application utilising IPFS for decentralised storage that anyone can upload documents to, download documents from, that also handles the academic peer review process. The application runs on individual PCs, all forming part of the IPFS database. This gives us an open source platform that cannot be bought out by the large publishers (and any derivitive works must also be open source) that should also be hard to take down due to the database being spread across the globe in multiple legal jurisdictions. Aletheia is designed to be a resilient platform run transparently by the community, not some black box corporation or editorial board, meaning all users can see the decisions Aletheia is making and have a stake in that decision making process if they so desire. By this nature, Aletheia is decentralised, it has no key person risk. Should the core group who invented Aletheia dissapear Aletheia won't cease to exist, it will continue to be run by the community. The community moderates content through various mechanisms (peer review, reputation scores etc.,) to ensure quality of content.

Apache CouchDB: Apache CouchDB is a distributed, fault-tolerant and schema-free document-oriented database accessible via a RESTful HTTP/JSON API. Among other features, it provides robust, incremental replication with bi-directional conflict detection and resolution, and is queryable and indexable using a table-oriented view engine with JavaScript acting as the default view definition language. CouchDB is written in Erlang, but can be easily accessed from any environment that provides means to make HTTP requests. There are a multitude of third-party client libraries that make this even easier for a variety of programming languages and environments.

Programs can be generated in Python, bash, ksh, Java, C, or other languages; the package also generates code for various database servers via a plain text file.

Autobench: Autobench is a collection of scripts to automate the benchmarking a web server (or for conducting a comparative test of two different web servers). It is a wrapper for httperf. Autobench runs httperf repeatedly against each host, increasing the number of requested connections per second each time. It extracts the significant data from the httperf output, and delivers a CSV or TSV file which can be imported directly into a spreadsheet for analysis or GNUplotted using the included bench2graph script.

Autotable: Autotabla is a CGI interface to a collection of SQL tables. Once an XML description of the database schema (table names, fields, etc.) is provided, all table maintenance can be done from a Web page. The program reads the database schema from a configuration file, and you can manage the tables included in the schema: you can add, delete or modify rows and you can do simple but effective queries. It is meant to help developers who are making SQL based applications, freeing them from writing basic scripts for accessing the tables the application will use, and letting them test those applications with live data that can be inserted, modified or deleted from outside it. It reads the database schema from an XML configuration file (which must be provided, and presents an index page of tables and operations to do with them. From then on, the user can do all typical table maintenance.

Awhttpd: 'Anti-Web httpd' is a single-process Web server that relies on its inherent simplicity to be robust and secure. It has support for virtual hosts, CGI, IPv6, and more. In its default mode, though, it is easy to launch and requires no configuration files. It implements the bare minimum of HTTP 1.1 necessary to be a productive web server. It doesn't support certain requests like HEAD (anymore), but normal users will never notice the difference. POST request support is in the works, as is HTTPS/SSL support.

Basapp: BasApp is a software for friendly creation of web applications, based on your own database structure. Once BasApp is installed in a webserver, the developer can do all the job with a web browser, same as final user.

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.

BlueSpice: BlueSpice extends MediaWiki and enhances it with useful features, in particular in the areas of quality management, process support, administration, editing and security.

Coldstore: ColdStore is a gigabyte-scale persistent object store which maps objects into a file (for persistence), can allocate objects in a minimal working-set of pages (for speed), permits library versions to change without a rebuild of the store, and permits application checkpoint/restart. Coldstore might be used to replace a database, cache highly structured objects, act as an OODB, make STL persistent, act as a Document Store for XML/SGML/HTML, create a MUD. Future projects include a virtual machine toolkit, ports of several languages, VW and byte-interpretive language workbench.

Comanche Server: Comanche is an extremely simple HTTP (web) server written entirely in Python. It does not use any of the many Python standard library modules related to HTTP serving, as it was initially written as a learning exercise. At present it does not support CGI or SSL and uses a simple fork-on-demand architecture, but is being actively improved.

Common Lisp SQL: 'CLSQL' is an SQL database interface for Common Lisp. It provides object-oriented and functional access methods to the underlying database, which can be one of MySQL, ODBC, PostgreSQL, or SQLite. It uses the Unified Foreign Function Interface (UFFI) and thus supports the CMU Common Lisp, Steel Bank Common Lisp, Allegro Common Lisp, OpenMCL, and Lispworks implementations.

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.

Csv2mysql: 'csv2mysql' is a Web-based tool that converts CSV files to MySQL tables. It asks for the location of the CSV file, type of the CSV file, and access info (server address, table name, username, and password) for the MySQL database, and lets users map the fields of a CSV file to the fields of a MySQL table.

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.

Ctrlproxy: 'ctrlproxy' is an IRC server with multiserver support. It runs as a daemon and connects to a number of IRC servers, then lets you to connect from a workstation and work as the user who is logged in to the IRC server. After you disconnect, it maintains the connection to the server. It acts like any normal IRC server, so you can use any IRC client to connect to it. It supports multiple client connections to one IRC server (under the same nick), so you can connect to IRC using your IRC nick, even if you have an IRC session open somewhere else. It supports logging (in the same format as the irssi IRC client), password authentication, and ctcp (in case no clients are connected).

DBA Companion: DBACompanion is a graphical administration tool for Oracle databases that lets you visualise the contents of a data dictionary. It lets you browse the data dictionary, drill down from one piece of information to related ones, generate SQL scripts based on data dictionary information, and customize all the SQL used by the tool.

DBI Frame: DBI::Frame is an extension of the standard DBI perl module, designed around MySQL, used to create and maintain frameworks for databases. It has query logging and a standardized interface for SQL statements like 'update' and 'insert' that doesn't require understanding SQL. Ideally, the user or developer shouldn't have to know SQL to be able to administer a database; this does require a special setup which isn't necessarily easy to create.

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.

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.

DaveDAP: * " 'DaveDAP' is now 'phpldapadmin'. " DaveDAP is a PHP-based engine to browse, search, and edit an LDAP server over the Web. You can browse your LDAP server in tree mode, or you can search for users based on any number of easily configurable criteria. Users can create and delete objects, edit their contents, and perform searches. DaveDAP aims to be a Web-based replacement for GQ.

Dia2sql-stl: 'dia2sql-stl' is yet another dia2sql converter. It uses libxml2 and the STL to quickly parse UML objects from a Dia diagram and then generates corresponding SQL code to create the tables specified in the UML diagram. It takes a filename and outputs to stdout.

Diaspora: Diaspora is a decentralized social network (composed by many servers which interact with each other, the servers are called pods).

Dico ,: Dico is a flexible modular implementation of DICT server (RFC 2229). In contrast to another existing servers, it does not depend on particular database format, instead it handles database accesses using loadable modules. The package includes several loadable modules for interfacing with various database formats, among them a module for dict.org databases and a module for transparently accessing WordNet. New modules may be written in Guile or Python. A console client program, dico, is also included.
