PostgreSQL-relay can be used to as a single point of origin for a number of databases. Instead of having to remember (or modify in case of changes) all the names of databases, on which machines and on which ports they are running, you only need to remember one machine and the name of the database. It will then forward the connection to the proper database on the proper port of the proper server.
arraymanip is a PHP class for manipulating data in arrays. It is capable of moving elements from one position to another, deleting elements, and inserting elements in specific positions. It supports mixed indexed arrays, although this isn't recommended. By default it works with integer indexed arrays.
eltclsh (editline Tcl shell) is an interactive shell for the Tcl programming language. It provides command line editing, history browsing, and variables and command completion thanks to editline features. The completion engine is programmable in a way similar to tcsh, and comes with built in completion for the entire Tcl language by default. The package also provides elwish, an interactive interpreter for the Tk toolkit. You need the editline library in order to compile eltclsh.
ORAPP is a programmatic API written in C++ around Oracle's OCI8 and OCI9 APIs. It does not use exceptions or RTTI, and so is very small, fast, predictable, easy to read, and easy to use. Like its predecessor ORA++, ORAPP's design was influenced by MySQL++ and thus should be familiar to those who have used MySQL's C++ interface.
dbo is yet another database object framework written entirely in Python. Tables are represented using schema objects that encapsulate column information and supporting metadata. Row instances are represented as a dictionary. Features include database independence (with Postgres and MySQL support), automatic type conversion, database schema extraction, sequence emulation, on-the-fly table joins, and more.
