Description: Active data refers to data that is currently being used or processed in real-time within a system or application. This data is essential for decision-making, analysis, and daily operations of an organization. Unlike inactive data, which may be stored without immediate use, active data is dynamic and constantly updated. Its relevance lies in its ability to provide up-to-date and relevant information, allowing businesses to quickly react to changes in the market or customer behavior. In the context of technologies such as ETL (Extract, Transform, Load), Data Lakes, NoSQL, Data Engineering, Databases, and Big Data, active data is fundamental for analysis and reporting. This data can be structured or unstructured and can come from various sources, such as enterprise applications, IoT sensors, social media, and more. Efficient management of active data is crucial to maximize its value and ensure that organizations can make the most of the available information.
