The OpenSceneGraph is an open source high performance 3D graphics toolkit, used by application developers in fields such as visual simulation, games, virtual reality, scientific visualization and modelling. It is based around the concept of a SceneGraph, providing an object-oriented framework on top of OpenGL. This frees the developer from implementing and optimizing low-level graphics calls and provides many additional utilities for rapid development of graphics applications. It supports view-frustum culling, occlusion culling, small feature culling, Level Of Detail (LOD) nodes, OpenGL state sorting, vertex arrays, vertex buffer objects, OpenGL Shader Language and display lists as part of the core scene graph. These together make the OpenSceneGraph one of the highest performance graphics toolkit available. The OpenSceneGraph also supports easy customization of the drawing process, such as implementation of Continuous Level of Detail (CLOD) meshes on top of the scene graph (see Virtual Terrain Project and Delta3D).

The PHP/Java Bridge is an implementation of a streaming, XML-based network protocol, which can be used to connect a native script engine, for example PHP, Scheme or Python, with a Java virtual machine. It is faster and more reliable than direct communication via the Java Native Interface, and it requires no additional components to invoke Java procedures from PHP or PHP procedures from Java. PHP Java bridge hepls to use Java objects in PHP scripts and it also invokes PHP script from Java object. A typical use would be having PHP front end with Java back end, which will use all services such as JMS, EJB, SOA etc.

LucidDB is the RDBMS built entirely for data warehousing and business intelligence. It is based on architectural cornerstones such as column-store, bitmap indexing, hash join/aggregation, and page-level multiversioning. Every component of LucidDB was designed with the requirements of flexible, high-performance data integration and sophisticated query processing in mind. 

 Rather than throwing hardware at data warehousing problems by relying on expensive clusters or specialized "appliances", the scalability offered by LucidDB's unique architecture allows you to achieve great performance using only a single off-the-shelf Linux or Windows server. Besides keeping costs down, this also minimizes maintenance and administration hassles. 
 <UL>
	<LI>Support of both 32 and 64 bit platforms</LI>
	<LI>Integrated with Pentaho Business Intelligence product</LI>
	<LI>Automatically adapts to either bitmap or btree representation depending on data distribution</LI>
	<LI>Versioning at page-level is much more efficient than transactional databases</LI>
	<LI>Supports incremental backup</LI>
	<LI>High performance and greater cache and disk effectiveness</LI>
	<LI>Allows flat files (e.g. BCP or CSV format) to be queried as foreign tables via LucidDB</LI>
