A i l l d d b ild hi d t t fi th d t i i d lA simple user can upload and build his datasets, configure the data mining modelsavailable, execute different experiments in service mode, load graphical views ofpartial/final results.Y t id i lf i l ? Ok thi k t bYou are not considering yourself as a simple user? Ok, so you think to be aDeveloper. Or at least a scientist who wants to upload and use his application (andpossibly to share it with others).
B h t d ’t t t l ’ li ti Be honest, you don’t trust someone else’s application. So You want to extend our framework?
DM Models DevelopmentDownload our DM Models library;
Add new low level/DM shared libraries and related new wrapper;Add new low level/DM shared libraries and related new wrapper;Extend the DM class hierarchy;
Model/Driver Plugin DevelopmentD l d SDKDownload our SDK;
Implement and test the DMPlugin abstract class;Provide a method to produce the plugin description and Submit for Registration;

The same if you want to develop a new driver for a specific environment or storage system. Just implement the Driver Plugin Interface and register it;
