This is just one example that I know of.
When analysing epidemiological data from large databases such as the GPRD (a UK database), pulling data refers to a specific "chunk" of data. Let's say you want to study prescription data from 2000 until 2010. You would purchase the rights to pull this data from the database.
After you have pulled the data, you would then filter out what you require
