dict_pgsql is a dictionary for the mailer postfix. It is able to get all virtual users out of a postgres database; this is very helpful if you have a large number of users who make updates on their aliases quite often. You don't have to extract all the values into system files; the entries will be fetched directly from the database.
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.
com.webprofusion.util.db.DBConnection is a simple wrapper Java object for JDBC database connections which is meant to help in building cross-DB SQL statements. It currently supports MySQL & MS SQL Server. It also includes the classes com.webprofusion.utils.StringUtils and com.webprofusion.SiteProperties. The dbconnection object currently uses thess classes to load settings for the DB Connection at runtime. This lets you define a properties file which specifies the dbengine and connection info.
ColdStore is a gigabyte-scale persistent object store which mmap()s 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, 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, VM and byte-interpretive language workbench.
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.
Arad-OneTable-Editor is a set of perl modules to manage and display a dialog for a single-table SQL query. It can verify types, and scroll between the records. The data handling is separate from the dialog class, so it is possible to write different generic dialogs for the same query. A Perl/Tk dialog and a GNU/readline (or plain text) dialog are included in the distribution.
