What is the focus of data engineering?

The focus of data engineering primarily revolves around the development and management of the architecture that enables data collection, storage, and processing. This process ensures that data is efficiently gathered from various sources, organized in a meaningful way, and made available for analysis. Data engineering encompasses a broad range of activities, from building data pipelines to data warehousing, which ultimately supports data analysis and decision-making efforts.

While data visualization techniques are important, they represent a later stage in the data lifecycle, where the engineered data is displayed for insights. Identifying data outliers is a specific task often performed during data analysis, typically focusing on the integrity and quality of the data already collected. Data cleaning processes, while essential as part of preparing data for analysis, are just a component of the overall data engineering process, rather than the primary focus. Thus, the correct answer highlights the comprehensive role of data engineering in setting up the entire framework for effective data flow and utility.
