What is the main focus of the discipline known as data engineering?

The main focus of data engineering is primarily on data processing. Data engineers are responsible for building and maintaining the architecture that allows data to be collected, stored, processed, and analyzed effectively. They design and implement systems that handle large volumes of data, ensuring that the data is structured and optimized for analysis and reporting purposes.

Data processing encompasses the workflows and methodologies used to convert raw data into a usable format for analysis, which is a key task for data engineers. This includes tasks such as data cleaning, transformation, and loading into databases or data warehouses, making data accessible and reliable for data analysts and other stakeholders.

While data collection, management, and analysis are integral to the data pipeline, data engineering specifically emphasizes the processes used to handle data and prepare it for further usage, which is why processing is the correct focal point in this context. Thus, understanding how data is processed is crucial for effective data engineering practices.
