| definition | Collection of generally unrefined or pre-processed (or raw) data captured and consolidated from multiple sources. It contains data with limited structure where data models are applied a posteriori, that is, after loading data into the lake. That is also known as data-first or schema on-read. Data in the lake might not be harmonised or integrated, and curation and quality assurance are not required. | ||||||
