In our days, the production of huge amounts of data and information in every aspect of the economy as a whole, has led many industries and organizations to exploit this unused information, because this exploitation generated enormous insight and profits. This led to the creation of new data analysis techniques and technologies and gave birth to the broader field of Big Data. In this paper, we present the capabilities of new Big Data technologies that help us analyze huge datasets and export helpful results based on them. More specifically, we make our computer ‘learn’ by processing files that present past user preferences in movies (based on their ratings), suggesting, based on this analysis, movies that we may like.
