Definition: "ETLpost" stands for "Extraction, Transformation, Loading, Processing". This term describes how information from a database or other data source is processed in order to extract useful insights or reports. The process typically involves three main steps: extraction (processing the data), transformation (convert it into something useful), and loading (into a suitable format for further analysis). It's often used to describe processes like Data Warehousing, where raw data is converted and transformed before being integrated with business logic.
