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.

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.

a framework library with a template method interface and inheritable classes for an executable process design which produces an executable which is both a GUI and a console application. It provides multi-threading for work items of the provider process .

ARMR provides a foundation for creating an efficient in-memory database. Its unique list processing structures simplify programming logic and allow the developer to rapidly sort, group, and select data. Give your app a hypercard like capability.

BinBase is a software for the automatic analysis of Massspec data from LECO GC-Tofs. All code and documentation has been moved to the google code site of this project: https://code.google.com/p/binbase/ And support is provided by the company coding and more, which can be reached under: contact@codingandmore.org

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.

C-squares is an easily implemented method for storage, querying and display of spatial data locations, based on a hierarchical, grid-based representation of the Earth' surface. Source code for encoding, decoding, mapping, etc. is provided via this site. Additional support is available by contacting the system developer, Tony.Rees@marinespecies.org; see also the c-squares home page at http://www.cmar.csiro.au/csquares/ .

CRCLIB is a small library of CRC calculations which can be used in other programs. Because CRC check is often used by binary communication protocols, it is made as simple as it can be, built into library so that it could be used regardless of language of application code. Written in plain C, built as dll and static library, and also contains C/C++ import header, C# wrapper and .NET project for MS SQL Server assembly. Supports CRC16 (including MODBUS) and CRC32.

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.

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.

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/

The project will be looking at data (the intention is to begin looking at customer name/address data but this may widen over time) and ways to intelligently detect duplicates using fuzzy matching methods and algorithms.

Isolate Project is a straightforward data retrieval software that connects to popular relational database management systems and performs search operations based on the criteria specified. This project aims to speedup data retrieval operations.

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.

JaQLib is a compact Java library that supports programmers in querying all sorts of collections, DBs and XML files in a compact and intuitive manner. Example: List<MyItem> result = Jaqlib.List.selectFrom(myCollection) .where(myCondition).asList()

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.

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)]

A simple, fast, embeddable, persistent key/value store written in pure Go. It supports fully serializable transactions and many data structures such as list, set, sorted set. It supports fully serializable transactions and many data structures such as list、set、sorted set. All operations happen inside a Tx. Tx represents a transaction, which can be read-only or read-write. Read-only transactions can read values for a given bucket and a given key or iterate over a set of key-value pairs. Read-write transactions can read, update and delete keys from the DB. NutsDB allows only one read-write transaction at a time but allows as many read-only transactions as you want at a time. Each transaction has a consistent view of the data as it existed when the transaction started. When a transaction fails, it will roll back, and revert all changes that occurred to the database during that transaction.

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

Red/Black Tree implementation. Port of the sourceforge libredblack library to C#. The package also consists of mutlitree (tree with non-unique key) and tree with quick direct access to items by the index.

Centre is a synthetic trajectory generator environment that aim to generate semantic-based trajectory datasets usable for spatio-temporal data-mining algorithms in testing and validation process.

TCache is high performance key/value storage component. It can be easily plugged into any existing high-performance, distributed memory object caching systems such as MemcacheD or Dynamo, speeding up dynamic web applications by reducing database load
