DB_Browser is a CGI tool for developers working with any relational database supported by Perl::DBI. It easily facilitates searching, editing, and adding to tables within a database. While it can be used as a regular interface to database data itself, it works well as a supplemental tool for developers creating their own primary interface.
Xindice is an open source Native XML Database. It stores and indexes compressed XML documents in order to provide that data to a client application with very little server-side processing overhead. It also provides functionality that is unique to XML data, which can't easily be reproduced by relational databases.
dbtcp is a package of libraries which provides applications on Linux access to ODBC datasources on remote machines running Windows. It allows a Linux application to access data held on a Windows machine (such as MS SQL Server on NT), and includes a command line client, a DBD, and a PHP driver.
DBOX is a free communication package for ISPs. It supports a large number of message formats such as RFC/UUCP, ZConnect, Janus/Janus2, Alphabox, and GSbox. It is designed for large installations and includes a WWW package with an email/HTML gateway, an HTML online shop, support for POP3/IMAP4, and personal homepages with HTTP/FTP upload.
dbMetrix is a graphical database tool written for the X Window System. It is based on the GTK widget set and supports multiple, simultaneous connections to various SQL servers such as MySQL, mSQL, PostgreSQL and Solid. It serves the function of an administration, client, dump, conversion utility.
DBMEdit is a web-based DBM database editor (in Perl 5). If you use DBM files and don't have a simple way to edit them, you'll want this. It treats each element in the DBM as several fields joined by a delimiter, in effect supporting multiple columns within the single-column DBM format. DBMEdit displays your DBM database as a table, and provides auto-sized forms to add or edit records. Multi- user access is safe.
DBMaker provides you with a professional database system with multimedia capabilities, a native ODBC interface, large database features, and cross-platform support. The unique open architecture and native ODBC interface give you the freedom to build custom applications using a wide variety of programming tools such as Visual Basic or Delphi, or query your database using existing ODBC-compliant applications.
The DBMAIL package replaces the normal UNIX mailing system. All email and user data is stored in a database. You can create an unlimited number of email accounts, which can be checked using the POP3 or IMAP protocol. Users can maintain their own set of email addresses. It is more scalable, more secure, and faster than traditional mail systems. DBMAIL has storage drivers for PostgreSQL and MySQL, and it has authentication drivers for PostgreSQL, MySQL, and LDAP.
DBIx::Password provides an abstraction layer for password maintenance. It is database independent and only overrides the connect method (so it basically behaves as DBI normally does). You provide a single virtual user name in the connect method and the module determines which database/which user/which password to provide.
