Open Source Database Engines/Servers

CLucene is a C++ port of Lucene: the high-performance, full-featured text search engine written in Java. CLucene is faster than lucene as it is written in C++.

i-doit is a web based IT documentation and CMDB. i-doit documents IT-systems and their changes, defines emergency plans, displays vital information and helps to ensure a stable and efficient IT operation: The technical documentation: This means that all information can be organised (details flexibly adjusted), stored and maintained in one place. This allows simple Helpdesk, Support and Planning functions and provides the basis for quality assurance and certification. i-doit allows services to be documented as a logical grouping of objects placed in relation to each other. This provides the basis for (ITIL) processes such as Change and Problem Management, helps to control and manage the SLA (Service Level Agreement) or the communication with users. Its interfaces to other ITSM applications (like Nagios, Request Tracker etc.) allow the entering of data only once in the ITSM environment. i-doit maintains one holistic view of the operational situation.

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

UnixODBC.pm provides a Perl API for the unixODBC driver manager and a bridge API for unixODBC network queries. The sample text-mode, GUI, and Web clients can manage multiple hosts and DBMSs and create RSS output.

A fast, modular, scalable, adaptable and cheap enterprise back-end for information management. Includes database functionality (hybrid IMDB), process management, business integration, etc. by the way of custom extensions to the system.

The BSBM (Berlin SPARQL Benchmark) suite for benchmarking RDF stores or RDB-2-RDF wrappers over the SPARQL protocol. Pure RDBMS benchmarking via SQL is also possible. Visit http://www4.wiwiss.fu-berlin.de/bizer/BerlinSPARQLBenchmark for more details.

The DbtuTools project is a framework for working with the UNIX / Wintel versions of IBM's DB2 UDB database family.

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.

Metakit is an efficient database library with a small footprint. It's a cross between flat-file, RDBMS, and OODBMS. Keywords: structured storage, transacted, load on-demand, portable, C++, Python, Tcl, instant schema versioning.

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

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

Sequoia is a database clustering middleware offering load balancing and transparent failover. Databases are replicated over multiple nodes and Sequoia balances the queries between them. Sequoia supports online maintenance and recovery operations.

mysql auth_ldap is an authentication plugin for the MySQL server. It allows you to create SQL users that are going to be authenticated using a LDAP server. This allows to minimize administrative duties, since your users will be able to reuse their existing account to access the database. The plugin requires MySQL 5.5.7 and up. It is compiled as an add on and does not require you to alter MySQL source code, or recompile the entire server. The plugin add support for LDAP using the openLDAP library.

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.

The JProgress project provides tools for connectivity with Java clients and the Progress database. JProgress provides an n-tier software architecture for database access for executing remote requests over WANs and the Internet.

This library implements several locality sensitive hashing(LSH) based algorithms, including indexing data structure for high dimensional spaces and metric spaces, sketch constructions and set embedding algorithms.

The Open Design and Integration Environment is a toolbox of C and TCL code designed to introduce people to programming in a friendly way. It is also designed to be robust enough to novices to develop useful applications.
