Big Data Processing: Techniques and Tools


The main goal of the course is to introduce students to modern techniques, systems and platforms for efficient management and processing of large-scale data. Emphasis will be placed on issues related to scalability, efficiency and error tolerance in the full lifecycle of large-scale data, from data collection to data completion and interpretation. In addition, issues related to the processing of multi-source data using processing services streams will be analyzed, with the aim of combining the information generated by the aforementioned data processing by the different flow services. Through this course, students are expected to acquire important technical skills in large-scale data management and learn to design and implement large-scale data processing algorithms.
