...FlockDB emphasizes horizontal scalability, replication, and support for high rates of writes and updates, as well as efficient paging through very large result sets. It is not a general graph database in the sense of supporting complex multi-hop traversal queries or sophisticated graph algorithms; instead it focuses on the core problem of storing and querying directed edges with attributes such as sort order, state (normal, archived, removed), and position. Edges are stored both in forward and backward directions to facilitate queries in both directions. The project is now archived and in read-only mode, meaning it's no longer actively maintained by Twitter.

MAPONTO is an interactive tool for discovering semantic mappings between database schemas and ontologies as well as between different database schemas. The tool analyzes semantics in the input schemas and ontologies for generating semantic mappings.

JoSQL (Java Objects SQL) provides SQL capabilities for querying, ordering and grouping of collections of Java objects (POJOs). It allows a SQL statement to be applied to the collection of objects and the matching set returned, ordered and grouped.

XTEA (eXtended Tiny Encryption Algorithm) support for db4o open source object database. XTEA is a block cipher that operates on a 64-bit block size with a 128-bit key. An extremely tiny but very fast encryption algorithm (with cycles less than 32 rounds)

Fast search using a standard SQL on Oracle or PostgreSQL database. The package includes the database creator, loader and web application. It supports SMILES and SMARTS substructure searches, similarity search, stereochemistry.

XPN is relies on a non relational native XML database, where XML documents are stored in a compressed form and indices enables fast access to structure and content, thus enabling a fast evaluation of XQuery queries.

Frag'n Alloc Tool is a software for supporting the development of a distributed database, implementing some fragmentation and allocation algorithms.

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.

Now part of Apache's Mahout machine learning project at http://mahout.apache.org/-- please see there for latest info and code and releases and support!

An adaptive mini database learns algorithmic operations for data intensive algebraic computational methods within a pervasive computing graph. It also provides generic structures and algorithms as a data fabric.

PHPersistencia is a database persistence layer for PHP, offering Object Oriented interface to access the data, generating sql queries transparently for insert/update, selecting data as object collection and verifing data types without database access

Java Component created to persist and work with trees (it doesn't matter the type of persistence). Based on "Nested Set Model of Hierarchies" by Joe Celko. [Componente Java para persistir y trabajar con árboles (no importa el tipo de persistencia)]

Bookinex is an application designed to index your collection of books, it supports scanning of Barcodes to recognize ISB Numbers and querying web services to collect data.

Library and application that implements some algorithms relative to database theory: closure of attributes, primary keys calculation, minimal dependencies set, normalization, etc.

Free scripts & examples- JSP, Eclipse, SQL, PHP, ASP, Win32 Batch, Javascript, Flash/Actionscript. -=-=-=-=-=-=- NOTE: This project is closed. For new development related to integrating Beyond Compare with Eclipse, see http://beyondcvs.sourceforge.net/

JXmlSql is a Java database API ( MySql, Oracle, Access )that eliminates JDBC code. JXmlSql allows developers to define application and prepopulation SQL statements inside xml files. Options for query, insert, update, delete, report and prepopulation SQL.

DBI++ is a C++ port of the famous Perl DBI module. Currently it just supports MySQL, but the goal is, to extend it to a driver-independent interface. License is LGPL, so it can be used in closed-source-software, too.

ReHash is an easy-to-use console-based hash calculation tool written in C++. It supports many algorithms and output formats and it can be fully configured using some of the many command-line arguments which can be passed to the tool.

The cache-optimized concurrent skip list is a set of algorithms for maintaining dynamic ordered mappings. Top-down balancing algorithms minimize cache-misses while using a per-node read-write spinlock to coordinate shared access. Designed for Linux 2.4.

Pattern recognition software package. It includes several classification and clustering algorithms. It can read data from a set of images, an ASCII file or a JDBC connection. A small TCP data server with its corresponding JDBC driver is included.

The place for algorithms, scripts, and open discussion of the issues of traffic behaviour statistical analysis. Aberrant Behavior Detection. Holt-Winters forecasting. RRDtool.

FPlus is an application that implements several database theory algorithms such as Fmin, tableaux, normalization, attribute closure, key calculation, efficiency, etc. Test the applet at: http://fplus.sourceforge.net

PostgresSQL Replicator is an open-source asynchronous (store&forward) replica engine that provides some data ownership models and many conflict resolution algorithms.
