the testing
technique that only uses information about something’s
interfaces (i.e., without regard to its implementation).
Contrast withgraybox
testing and
whitebox
testing.
a value that lies on the boundary of a specified range of
valid input, internal, or output values.
Note that defects are often produced by errors
involving boundary values.
Example is the “off by one” defect in the coding of
loop variables.
a test coverage criteria that requires that each decision
point of each possible branch be executed by at least one
test case.
Also known as decision coverage.
Contrast withcondition
coverage,
path coverage, and
statement
coverage.
a
network
connectivity device that connects two networks or physical
network segments by operating at the data link layer of the
OSI model.
Note that bridges are useful for small networks using
protocols that cannot be routed. Bridges selectively
determine the appropriate setment to which to pass each
signal.
a
network
connectivity device that connects two networks or physical
network segments by acting as a
router for routable
protocols (e.g., TCP/IP) and as a bridge for nonroutable
protocols (e.g., NetBEUI).
Note that a brouter thus combines the strength of
both bridges and routers, but are more complex and expensive
than either.
a client software
tool enabling the display and navigation of
webpages and the
execution of associated execuable files (e.g., sound and
video clips, Java applets) over the
World Wide
Web.
either the current or reengineered
architecture of a
business capturing its major components (and their
responsibilities and relationships) as well as its major
mechanisms (i.e., how these components collaborate to meet
the requirements of the business
enterprise).
a
model of the business in
terms of the terminology of the
domain experts and
users without regard to any
specific system or software
application. The
main objectives of a business model are to formally represent
the business in terms of the essential business objects and
how they collaborate to perform the major business processes.
The business model forms the basis for understanding and
engineering (or reengineering) the business and its
processes. The business model typically consists of a
business-level
use case model and
associated
object model.
the architecture work product produced during business
engineering that documents the object model of the customer
organization’s newly architected business.
the second phase of the business engineering cycle during
which the development organization helps the customer
organization optimize all or part of its business enterprise
by implementing, communicating, and continually optimizing
its new business strategies and architectures.
a
server
computer used to handle communication between a data
center and the associated business’ business partners
and suppliers as well as to support partner and supplier
management.
the architecture work product produced during business
engineering that documents the customer organization’s
plans for transitioning their business based on the results
of business engineering.
a
network in which all
computers are connected via a single cable with a terminator
on each end.
For example, an Ethernet network that is connected
with Thinnet coaxial cable.
Contrast withmesh network,
ring network, and
star network.
