Hi, I want to use Oracle Database Enterprise Edition and Oracle Data Mining for my master's degree thesis and maybe we can publish a science paper in the end. I have already downloaded the database and working on it but I need to know if it is all right to use the software for free while preparing my thesis. Is there anything I should pay or should I inform Oracle about it? I do not know anything about using Oracle products for research projects. Any information you provide will be appreciated. Thanks, Hatice
