Berkeley DB XML is a native XML database engine for use within your product. Made available as a C++ library with language bindings for Java, Perl, Python, PHP, and Tcl, it integrates directly into your application (it is not a standalone database server). It provides XQuery access into a database of document containers. XML documents are stored and indexed in their native format using Berkeley DB as the transactional database engine.
dbMan is a complex SQL monitor for common database systems (PgSQL, Oracle, MySQL etc.). It's based on Perl and DBI interfaces. Features include a command history buffer, tab completion, editing Oracle objects, simultaneous connections, SQL help, importing and exporting of tables, Oracle explain plan, and more. dbMan is made as a simple kernel and many extension modules, and you can make your modules with a simple HOWTO.
AppWrap is a content management system for enterprises. It is built on a template engine that includes a framework for building SQL tables and allowing users to populate and maintain these tables. Reports using data from these tables can be easily created using another template. It is ideal for quickly Webifying Excel and Word files shared among workgroups and rapidly providing advanced data management and presentation capabilities. It is intended for managing mildly dynamic data without the labor of hand-coding and managing multiple CGI forms and templates, or the expense of CRM systems.
The DBIWrapper is a Perl Module that provides for easier access to databases using DBI. It supports MySQL, PostgreSQL, and ODBC DBD modules. High level methods for reading, writing, commiting, and rolling back transactions to the database are provided. XML or DBI data structures can be used.
UnixODBC.pm provides Perl programs with a subset of the X/Open ODBC API for use with EasySoft's unixODBC DBMS libraries, as well as a peer to peer API for querying ODBC data sources on networked systems. In addition, it provides peer client and server scripts and configuration files, sample clients that perform ODBC queries on local and networked systems, result set output for RSS feeds, and two multi-host data managers: one that uses Apache and CGI to provide a Web browser interface, and another that uses Perl/Tk.
Net::Z3950::SimpleServer is a Perl module which implements the server side of the Z39.50 (information retrieval) protocol. It hides the complexity of network exchanges, packet serialization, and session handling. You are required only to implement simple callbacks to support searching and record retrieval. It is the basis of the "Zoogle" project, which is a Z39.50 gateway to the Google web index.
The DBIx::Perlish module provides the ability to work with databases supported by the DBI module using Perl's own syntax for the four most common operations: SELECT, UPDATE, DELETE, and INSERT. By using DBIx::Perlish, you can write most of your database queries using a domain-specific language with Perl syntax. However, the module is not intended to replace all use of SQL in your program. The DBIx::Perlish module quite intentionally neither implements nor cares about database administration tasks like schema design and management.
Zero RRD Framework provides a central HTTP-based service for importing into standard RRD databases and for generating graphs. A lightweight, easily extendable agent for the data sources pushes updates with minimal resource consumption to the master service using HTTP. With the introduction of VMs for the service, it's easy to test-drive the application and even the architecture (connecting agents to the service in the VM).
