The course is addressed to managers of all levels and business users, including analytics. Its participants will be given the practical overview of the most important, but often forgotten newest Microsoft Bi technologies — Power Query.


The basic training is comprised of 8 modules. Just like all the other courses on our offer, it has been designed by our experts, therefore we can freely customize it to suit the individual needs of the participants.  We would like to encourage you not only to choose modules which you find relevant for your needs, but also to feel free to contact us with your suggestions and questions you would like to hear answered during the course.
Our trainings are unique also because we limit the time set aside for laboratory type classes customarily conducted after the completion of each module, to the benefit of exercises done with the assistance of the trainer and demonstrations. We believe in this manner we can equip you with substantially more practical information and tips, and focus on dealing with the issues directly within your scope of interest. However, each day of the training is finished with a laboratory class of approximately 1hr, so that you can do self-practice and do exercises of your choice.
