Complex Data Analysis


The purpose of this program is to help students learn the skills required to work as a data analyst or data researcher and build a career in data science. This master covers three type of knowledge required in the field:

(1) Programming languages required for data management and construction of data warehouses: SQL (1 course), Python (4 courses), R (three courses); Power Query (1 course).

(2) Visual data exploration tools: types of graphs, dashboards, infographics and types of reporting using specialized tools such as Excel, PowerBI, Tableau, ArcGis.

(3) tools for predictive statistical and dimensional analysis: R, JASP, Excel, ArcGIS, RapidMiner.

(4) mastery of machine learning algorithms (3 courses in Python): algorithms for data reduction and prediction, natural language processing, neural networks.

The courses provided by this master’s program will cover aspects of population segmentation theory at urban, regional, national and global levels, as well as theories of segmentation processes.


The courses require logical thinking;
No prior knowledge of statistics is required;
No knowledge of mathematics is required;
No prior knowledge of programming languages is required.

Over the past fifteen years, the service sector has recorded gradual growth, so today it generates a quarter of Romania’s gross domestic product. Services exports have quadrupled in the past ten years. The fastest growing subsector in this sector is information technology, which accounted for 9% of  GDP in 2019 and is the second largest contributor to GDP growth  (1%). In 2017, the field had about 120,000 employees. Cluj and Bucharest centralize half of the country’s IT operations.

The field of data analytics is increasingly important in these service activities. Both those with knowledge of programming languages ​​and database queries (hard statistics) as well as those with skills in computer science and soft statistics work in this field. There are three types of data science-related careers available, and this program prepares students to work as data analysts and data researchers.
