This refers to the ability to query and update information regardless of the hardware platform on which the data resides.
A single query from a PC might retrieve information from
- an IBM 3090,
- a local database on the PC, and
- an HP-9000
in a single transaction.
Of course, a Net8 implementation does not care what type of processor is included in the network.
Hardware independence refers to the ability to execute a select statement and update data regardless of the underlying platform on which the data resides.
For example, a single query initiated on a Mac might retrieve information from an
- IMS on a mainframe,
- a Lotus database on a PC, and
- an Oracle database on a midrange host.
