Definition - What does Data Repository mean?
Data repository is a somewhat general term used to refer to a destination designated for data storage. However, many IT experts use the term more specifically to refer to a particular kind of setup within an overall IT structure, such as a group of databases, where an enterprise or organization has chosen to keep various kinds of data.
Some experts refer to a data repository as a partitioning of data, where partitioned data types are stored together. It is also commonly called data warehousing.

One of the simple premises for this kind of setup is that by keeping different kinds of data together, yet separated by a database or other container, business leaders can facilitate data mining and related research that can help with overall planning.
One issue in pursuing the construction of a data repository is security. It may make sense to have massive amounts of data collected in one physical space, but in some cases, remote backup may be a critical aspect of securing data.
