What is Data engineering?

Data engineering is the field that focuses on designing, building, and maintaining data infrastructures. It involves ETL pipelines, data storage solutions, and database optimization to support analytics and AI-driven workflows.

Data re-identification
Data re-identification is the process of reversing data anonymization techniques to identify individuals within a dataset. It poses privacy risks, as previously de-identified data can be matched with external sources to reveal sensitive personal information. This issue is addressed by privacy regulations such as GDPR, which impose strict penalties for unauthorized re-identification.
Internet of Things
The Internet of Things (IoT) connects physical devices, sensors, and software to exchange data over the internet. IoT is used in smart homes, healthcare, industrial automation, and connected vehicles, driving digital transformation and real-time decision-making.
Data Mart
Data mart refers to a subset of a data warehouse that is focused on a specific business function or department. It provides tailored access to relevant data, improving query performance and decision-making for targeted analytics and reporting.
