Data engineering is a field of computer science and information technology that focuses on the design, development, and management of data pipelines and infrastructure to support data-driven applications and analytics. It involves the process of collecting, transforming, and storing data in a way that enables efficient data processing and analysis.
Data engineering is a crucial aspect of the data lifecycle, as it ensures that data is reliable, accessible, and ready for analysis by data scientists, analysts, and other stakeholders. Data engineers work closely with data scientists, database administrators, and software developers to build and maintain data pipelines, databases, and data warehouses.
