ISDS 406; Final Exam; ch. 9Scree - correct answer ✔
Acknowledgement Message - correct answer ✔Messages are the way in
which the system responds to a user and informs him or her of the status of
the interaction. There are many different types of messages, such as error
messages, confirmation messages, acknowledgment messages, delay
messages, and help messages
Aesthetics - correct answer ✔Aesthetics refers to designing interfaces that
are pleasing to the eye. Interfaces do not have to be works of art, but they do
need to be functional and inviting to use. In most cases, "less is more,"
meaning that a simple, minimalist design is the best.
Bar code reader - correct answer ✔An example of SOURCE DATA
AUTOMATION; Stores commonly use bar code readers that automatically
scan products and enter data directly into the computer system.
Batch processing - correct answer ✔With batch processing, all the input
transactions collected over some period are gathered together and processed
at one time in a batch.
Batch report - correct answer ✔Batch reports are those that report historical
information that may be months, days, or hours old, and they often provide
additional information beyond the reported information (e.g., totals,
summaries, historical averages).
Bias - correct answer ✔The problem with bias is that it can be very subtle;
analysts can introduce it unintentionally. Bias can be introduced by the way in
,which lists of data are sorted, because entries that appear first in a list may
receive more attention than those appearing later in the list.
Breadcrumbs - correct answer ✔a listing of the page hierarchy
Button - correct answer ✔A navigation mechanism
Check box - correct answer ✔a graphical user interface element that permits
the user to make multiple selections from a number of options
Check digit check - correct answer ✔There are six different types of
validation checks: completeness check, format check, range check, check
digit check, consistency check, and database check. (Figure 9-20.) Every
system should use at least one validation check on all entered data and,
ideally, will perform all appropriate checks where possible.
Combo box - correct answer ✔a text box that contains a predefined list of
acceptable entries but permits the user to enter a new value when the list
doesn't contain the desired value
Completeness check - correct answer ✔verifies that all required data is
entered; There are six different types of validation checks: completeness
check, format check, range check, check digit check, consistency check, and
database check. (Figure 9-20.) Every system should use at least one
validation check on all entered data and, ideally, will perform all appropriate
checks where possible.
Confirmation message - correct answer ✔When the user is about to perform
a critical function that is difficult or impossible to undo (e.g., deleting a file), it
is important to confirm the action with the user (and make sure the selection
was not made by mistake). This is usually done by having the user respond to
, a confirmation message that explains what the user has requested and asks
the user to confirm that this action is correct.; There are many different types
of messages, such as error messages, confirmation messages,
acknowledgment messages, delay messages, and help messages (Figure 9-
17).
Consistency - correct answer ✔Consistency in design is probably the single
most important factor in making a system simple to use, because it enables
users to predict what will happen. When interfaces are consistent, users can
interact with one part of the system and then know how to interact with the
rest—aside, of course, from elements unique to those parts. Consistency
usually refers to the interface within one computer system, so that all parts of
the same system work in the same way.
Consistency check - correct answer ✔In a database, compares the values of
data in two or more fields to see if those values are reasonable; There are six
different types of validation checks: completeness check, format check, range
check, check digit check, consistency check, and database check. (Figure 9-
20.) Every system should use at least one validation check on all entered data
and, ideally, will perform all appropriate checks where possible.
Content awareness - correct answer ✔Ability of an interface to make the
user aware of the information it contains with the least amount of effort by the
user
Database check - correct answer ✔compare data against a database or file
to ensure they are correct; There are six different types of validation checks:
completeness check, format check, range check, check digit check,
consistency check, and database check. (Figure 9-20.) Every system should
use at least one validation check on all entered data and, ideally, will perform
all appropriate checks where possible.
