homogeneous environment encountered in traditional mini and mainframe
programming.
2.8)
An information system is a part of the database system.

The verification process does not includes the integration of all the different end-user
views of the database, each with its own set of requirements and transactions.
2.14)
The ODBC middleware provides the applications programmer with a generic format for
data access.
2.15)
