Not long ago we showed off the new capa­bil­i­ties of GraphDB 2.1 (to be released at the end of 2011) regard­ing the visu­al­iza­tion of data. Now we extended that capa­bil­i­ties and added another Out­put Plug-In to the Com­mu­nity Edi­tion. It’s called GraphVis.

And you can down­load it now with our source-code pack­age from our GitHub repos­i­tory.

The best way to show-off the new func­tion­al­ity is by lit­er­ally show­ing it:

A good start for the doc­u­men­ta­tion of the new visu­al­iza­tion options is our ever grow­ing wiki.

For many sce­nar­ios it’s impor­tant to know how a data­base per­forms. Espe­cially these days when the num­ber of data­bases seem to grow by the day and a choice is hard to make.

To demon­strate how sones GraphDB per­forms at given use-cases we cre­ated a bench­mark frame­work and tool which basi­cally divides bench­mark­ing into two steps:

1. Gen­er­ate and/or Import use-case spe­cific data and mea­sure the performance

2. Exe­cute use-case spe­cific algo­rithms on the graph and mea­sure the performance

Because there are many dif­fer­ent use-cases these both steps are made up by plug-ins which can be adressed using the com­man­d­line which is inte­grated into the bench­mark tool.

The frame­work, tool and plug-ins are released as AGPLv3 licensed Open­Source soft­ware and can be down­loaded here.

We dis­trib­ute the source code mainly because it’s the best way for you to repro­duce the results and take a look at what actu­ally is being tested, the other main cause is that we want every­body to be able to bench­mark and test their own algo­rithms on GraphDB.

Because of the high inter­est on our CeBit 2010 demo, here some pic­tures, videos and back­ground information:

Together with UID – a com­pany spe­cial­ized on user inter­face design – we cre­ated a graph data­base demo for the Microsoft Sur­face table. The demo showed the Ger­man Cor­pus based on one mil­lion sen­tences, 812K words and 118K sources and is described in detail here. For the visu­al­iza­tion we used our Visu­al­Graph Tool described here. Each day dur­ing the CeBit we pre­sented it at MSDN Devel­oper Kino.

More Back­ground infor­ma­tion avail­able here, here and here
