Data engineering is a skill that's used to collect and analyze data. Then, it can be used to understand the data's quality and make predictions about it. This makes it an essential skill for cyber intelligence professionals to ensure that their systems collect good quality information to make accurate predictions.
Data science is a large field with many different sub-specialties, and data engineering is one such specialty. Its focus on understanding how systems work means that these professionals have an affinity for building things from scratch; this includes programming languages like Python or R rather than just using pre-existing software packages available via third-party vendors (such as Google Analytics).
