The ExtenDB Parallel Server is a clustered database solution for data warehousing and business intelligence. It leverages the PostgreSQL database running on PC-based commodity hardware, and intelligently coordinates work between them. This allows for the scaling out of databases to handle large data volumes quickly.
StelsDBF is a DBF JDBC type 4 driver that allows the user to perform SQL queries and other JDBC operations on DBF files (such as those used by dBase III/IV/V, xBase, and FoxPro). The driver is completely platform-independent and does not require installing additional client or server software to provide access to DBF files. It can be effectively used to create, process, and export DBF databases in your Java applications. It supports most keywords of ANSI SQL'92; inner and outer table joins; CREATE, INSERT, UPDATE and DELETE statements; transactions; aggregate, numeric, and string conversion; and user-defined SQL functions.
phpDatabase.net is a pure PHP database script which can be used for an application as a light-weight database. It implements basic database functions like creating and dropping database; creating, changing, and dropping tables and sequences; selecting, inserting, updating, and deleting data from tables; automatic locking of files, so simultanous changing the data is possible; transaction processing, commiting, or rolling back of changes; and a default auto-commiting mode. It is packaged as a single PHP script.
kds (krico's distributed storage) is a distributed storage system. Its main goal is to work as a session handler for PHP. This package provides four components: a daemon (kdsd), a command-line cilent (kdsc), a library (libkds), and a PHP session handler extension. kdsd is a daemon that uses worker threads to process KDSPROTO requests. It then retreives or stores data in a BerkeleyDB storage. A nice little curses program is also supplied to monitor the storage state.
SQLiteDBMS is a database management server for SQLite. It allows an sqlite3 process to be accessed via a TCP/IP network. It provides Extended SQL, SSL, basic authentication, query caching, WebDAV, access control, and replication. It includes a simple Web server that takes HTTP requests and sends XML responses.
HDB is a small, flexible, and efficient hybrid database, a mix between a filesystem and a database. It comes with a wide range of command line utilities for manipulating and extracting data. It's designed for both embedded and bigger systems. It currently has interfaces to C, C++, Java, and Perl.
