Open Source Distributed Computing Software

Blazegraph has moved to Github. Please see https://github.com/blazegraph/database/.

The project aims at developing J2EE Connector Architecture 1.0 Compilant Resource Adapters for integrating various EIS's like XML files, XML DB, LDAP, FTP, SMTP, POP3, Point Of Sale, Properties File, Office Documents

Ridiculously simple, Prevayler provides transparent ACID persistence and replication for plain old Java objects. It is literally several thousand times faster than using a relational database through JDBC.

ActiveGrid is an Enterprise Web 2.0 solution that allows the composition of code-free applications that comply with corporate IT standards. Technologies include Python, Java, XForm, Xpath, WSDL, CSS, XML Schema (XSD), XACML, and BPEL.

JCA compliant connectors for the Berkeley Database system.

Postgres-XL is a PostgreSQL-based scale-out cluster that handles both OLTP write intensive workloads as well as OLAP/BI type of workloads thanks to MPP parallelism. Postgres-XL is fully ACID and supports cluster-wide Multi-version Concurrency Control (MVCC) for global consistency and performance. There are commercial companies such as 2ndQuadrant, who provide support and consulting around Postgres-XL. Please visit http://2ndquadrant.com/en/resources/postgres-xl/ for more details.

Moved to sf.net/projects/cloveretl/ !!! CloverETL is a Java ETL framework which transforms structured or unstructured data. Works as a standalone application or embedded in other applications as a data transformation library of functions.

Colle is the glue of a properly designed web application. It is written on several popular technologies of the Java and XML world including Servlet API, EJB 2.0, XSLT, JDBC, XML Schema, jdom, JAXP and others.

Momoko is a framework for developing distributed, multi-user, network-aware applications. It includes facilities for storing objects in a tree structure, a shell for manipulating the object database, orthogonal persistence, scripting support, and a trans

Sqlcached is a memory cache daemon, inspired by memcached, but offering more granular control by using SQL interface instead of key-value pairs.

VJDBC (Virtual JDBC) is a JDBC type 3 driver which provides efficient tunneling of JDBC commands/results over different communication protocols (RMI, HTTP, HTTPS ...).

Atomatrix is a multithreaded execution system of atomic matrices with a dynamic compiler and a network eviron. It is the next generation object-orientated environment. XML, MUD-OO CLI, GnucDNA support, windows and many subprojects are built-in.

Askemos is an autonomous, distributed operating system, which significantly raises the level of abstraction in comparison with todays operating systems. An alternativ, equally valid view is that of an XML object store with procedures in XSLT.

Brain Net. A Distributed Search Engine Network. Aims to be a scalable distributed search engine allowing dynamic connection of nodes. Performance depends on bandwidth.

A unique persistence layer for Java. CODO (Cursor Oriented Data Objects) maps generated Entity interfaces (suitable for DTOs) to a relational database via rendered SQL, reflection and JDBC Cursors where possible - avoiding associations.

Cheshire3 is a fast Z39.50, SRW, XML search engine, written in Python for extensability and using C libraries for speed. Next generation of the Cheshire system (http://cheshire.berkeley.edu) and designed around a distributable, object oriented model.

CloudBase is a data warehouse system for Terabyte & Petabyte scale analytics. It is built on top of Map-Reduce architecture. It allows you to query flat log files using ANSI SQL. Visit CloudBase home page for details- http://cloudbase.sourceforge.net

Cloud Target is a front-end to the python scripts that google uses to create, run and upload projects to its App Server system. This .NET application is based on the OSX front-end provided by Google in the SDK.

A framework for building, deploying and managing well-described REST-ful Web services, including REST-ful Web Services realizations for RSS, XML Topic Maps, Structured Arguments, and Workflow.

Cos provides a high level interface to application developers wishing to manipulate objects stored in a corportate wide data source lightweight data entries are manipulated by services that are able to appear and dissapear across the network as needed.

DataBase Copy for Synchronization

DBReplicator is a powerful open-source java application for network-based multi-master heterogeneous database replication or filtered synchronization.

EmGeeGen is a server-client information distribution system, tailored for use with the EmGee role playing system (though the theoretical platform should be useful for a variety of tasks).

The goal of this project is to make possible to access Progress database from any external program that can use sockets. The server (broker and agents) are written in Progress 4GL and made use of sockets capabilities of Progress V9.

HadoopDB is a hybrid of parallel database and MapReduce technologies. It approaches parallel databases in performance and efficiency, yet still yields the scalability, fault tolerance, and flexibility of MapReduce systems.
