MIS 301 Ch. 5 - Data and Knowledge
Management
Data Degradation - correct answer ✔customers move to new addresses,
change their names, etc.


Data Rot - correct answer ✔refers primarily to problems with the media on
which the data are stored. Over time, temperature, humidity, and exposure to
light can cause physical problems with storage media and thus make it difficult
to access the data.

documents

experiences


External Data Sources - correct answer ✔commercial databases,
government reports, and corporate Web sites

across an entire organization involving a formal set of unambiguous rules for
creating, collecting, handling, and protecting its information.

Data redundancy - correct answer ✔The same data are stored in multiple
locations.


Data isolation - correct answer ✔Applications cannot access data associated
with other applications


Data inconsistency - correct answer ✔Various copies of the data do not
agree


Data security - correct answer ✔Because data are "put in one place" in
databases, there is a risk of losing a lot of data at one time. Therefore,
databases must have extremely high security measures in place to minimize
mistakes and deter attacks.


Data integrity - correct answer ✔Data meet certain constraints; for example,
there are no alphabetic characters in a Social Security number field.


Data independence - correct answer ✔Applications and data are
independent of one another; that is, applications and data are not linked to
each other, so all applications are able to access the same data.


Relational Database Model - correct answer ✔is based on the concept of
two-dimensional tables and is usually designed with a number of related
tables with each of these tables contains records (listed in rows) and attributes
(listed in columns).
