Hi,
May I share my two-cent worth regarding
'retrieval'.
First, what Meriam Webster talks about is
database system management techniques. Its definition has a fault. For example,
'retrieval' has
nothing to do with recovering process, which is designed to restore
original data and database integrity when the system behaves
abnormally, or crashes.
Second, among the other three
dictionaries, the definition of American Heritage is the best one since
data is actually stored on and retrieved from storage devices. Because
storage devices are part of a computer, one can imply that the data is
stored on a computer or computer system. In other words, all three
dictionaries talk about the same thing.
'
Retrieval' or 'data retrieving process' is part of
database management system (DBMS) overall process. While
data storing process helps put data on a computer (system)'s storage devices,
data retrieving process helps users get / read / access the data from the storage devices.
