What is "data transformation" in the context of Power BI?

Data transformation in the context of Power BI refers to the process of changing data into a more usable format. This can involve a variety of actions, such as cleaning the data, filtering out unnecessary information, changing data types, aggregating data, and reshaping the data structure to suit analysis needs. The goal of data transformation is to prepare and enhance data, making it more suitable for analysis and visualization, which is a core aspect of utilizing Power BI effectively.

The other options, such as visualizing data outcomes, storing data securely, and creating automated reports, do not specifically address the core concept of data transformation. Visualizing data pertains to the generation of graphs and charts from datasets, securely storing data relates to data governance and protection, and creating automated reports focuses on streamlining report generation processes. Each of these functions is important within Power BI, but they do not encapsulate the transformative processes that data undergoes to be effectively analyzed.
