Data extraction is the retrieval of data from data sources, typically in the interest of merging this data into a larger repository (like a data warehouse) in order to improve accessibility, correlate with other data or combine different data sources into a single, homogeneous data set.

Data extraction can include data transformation at the point of extraction - for instance normalisation or filtering of data can be applied at the time of extraction, or at the time when it is loaded into the target data repository.
