A database, or alternatives such as the file system, can be used as data tier.

AT&T revised their cellular data plans to create data tiers for specific types of usage.

Cleveland does not include an explicit data tier, but defines information as "the sum total of...facts and ideas".

In three tier architecture, application tier and data tier will be in different hosts.

The data tier is not exposed to the client tier; only the application tier is.

The data tier and application tier can exist on different physical or virtual servers as well, provided they are running Windows Server 2003 or later.

Team Foundation Server works in a three-tier architecture: the client tier, the application tier and the data tier.

Three-tier architectures typically comprise a presentation tier, a business or data access tier, and a data tier.

In the latter, the data tier of the DIKW model is preempted by an assertion of neutral monism.

The data tier is queried by the logic or business tier when information is needed using a data retrieval language like SQL.

Another benefit may be adding an integration tier that separates the data tier from the rest of tiers by providing an easy-to-use interface to access the data.

IE 3G is now the norm, when "4G" is the norm will the unlimited data tier become 3G?

The negative effects on testability in the active record pattern can be minimized by using mocking or dependency injection frameworks to substitute the real data tier with a simulated one.

Such a tight coupling between the application tier and the data tier introduces knowledge of the underlying NAS to the application servers which should be avoided.

In a typical multi-tier or N tier architecture information is maintained in a data tier where it can be stored and retrieved from a database or file system.

Some would additionally point out that the inclusion of OO language functionality in the back-end simply facilitates bad architectural practice, as it admits high-level application logic into the data tier, antithetical to the RDBMS.
