OrientDB is a NoSQL DBMS which can store 150,000 documents per second on common hardware. Even with a document-based database, the relationships are managed as in graph databases, with direct connections among records. You can traverse entire or parts of trees and graphs of records in a few milliseconds. It supports schema-less, schema-full, and schema-mixed modes, has a strong security profiling system based on users and roles, and supports SQL between the query languages. Thanks to the SQL layer, it's straightforward to use for people skilled in the relational world.
TomP2P is a P2P-based high performance key-value pair storage library. Each peer has a table (either disk-based or memory-based) to store its values. A single value can be queried or updated with a secondary key. The underlying communication framework uses Java NIO to handle many concurrent connections.
Kangas Sound Editor lets you synthesize sound effects and music effectively from scratch. Musical pitches are constructed using a system of frequency ratios, rather than the conventional equal-temperament notation. MIDI pitch numbers can be used to specify a base note from which other notes are relative. The user interface uses a system of cells or boxes, which are placed using drag and drop, and that have associated properties which describe various characteristics of the instrument, sound, or chord group. There is a kangaroo theme to this software.
The Building Information Model server (BIMserver) software enables you to host your own BIMserver to centralize the information of any construction (or other building related) project. The core is based on the open standard IFC and therefore knows how to handle IFC data. The BIMserver is nót a fileserver; IFC data are interpreted by a smart EMF e-core and stored in an underlying key-valuestore database (Berkeley). It’s ideal to support your dynamic collaboration process in the AEC sector.
jOOX stands for Java Object Oriented XML. It is a simple wrapper for the org.w3c.dom package to allow for fluent XML document creation and manipulation where DOM is required but too verbose. jOOX only wraps the underlying document and can be used to enhance DOM, not as an alternative. It is inspired by jOOQ and jQuery.
BlackHole is an data de-duplicating network block device that also supports mirroring, snapshots, and support for multiple LUNs using the same data store. It is filesystem agnostic and has been tested with ext2/3/4, NTFS, ReiserFS, and the Oracle Cluster File System (OCFS2). It supports encryption, compression, and multiple storage backends. The hashing scheme used is user configurable. The program exports an NBD device which can be mounted in Linux and GNU/Hurd.
ERDesignerNG is a Java-based entity relationship design and database modeling tool. It has a powerful WYSIWYG interface for physical database design, supports 2D and 3D database modeling, browsing, and design, handles tables, relations, indexes, and comments, supports a central repository for all models (Model Repository), supports subject areas, supports domains, supports MySQL, Oracle, Microsoft SQLServer, PostgreSQL, and H2, creates the SQL DDL statements for schema creation, has an integrated schema version control system, can generate schema migration scripts for every change, stores the database definition as XML files for further processing, can export the database schema as GIF, BMP, JPEG, or SVG files, has an integrated reverse engineering module for existing schemas, has a build in schema compare feature, can generate schema documentation as PDF, HTML, RTF, and other formats, and supports schema conversion between different dialects.
