1.      The
course textbook states that “most business initiatives succeed or fail
based on the quality of their data” (Turban, Volonino, & Wood, 2015,
p. 37). With excellent information technology available today to manage data,
why do organizations still have information deficiency problems?

Information deficiency occurs when
the data that is collated does not meet standards or when the data lacks
information which may benefits the enterprise.

One of the main reason that
organizations or enterprises have information deficiency issues is due to the
that there is a vast amount of data available, therefore there is a difficulty
for the organization to pinpoint which data provides the proper information.
Moreover, if there is no standardization of data available, one will find it an
issue to isolate the correct data, there will only be a good data or a better
data. Secondly, the data available to the organization are not sorted out in
table format which allows better comparison. Imagine attempting to compare the
data in a random alignment, without a table, it will be easy for human error to
occur. Therefore, infrastructure is implemented to help process data
collection, however the collection of data must be in place from the beginning
of the start of the enterprise for the infrastructure to work. Another reason
that most organization have information deficiency is due to some of the
workers in the organization which keeps personal copy of the database, these
will lead to them changing their personal copy of the data instead of the
database system provided by the company. This will lead to the inaccuracy of
the data, as any changes should be updated in the database system at once.
Lastly, enterprises require large amount of financial funding to enhance their
information technologies, and such technologies is not cheap and therefore some
enterprises might be running on a more obsolete database which might have flaws
or bugs (Sutcliffe and Weber,
2003).

Hardware virtualization is a widely
utilized technology in the business world for purposes of reducing energy and
providing scalability with load-balancing. Describe three major types of
virtualization utilized by businesses.

Answer:

Network virtualization – This
virtualization allows the server to operate like several servers by tasking a
single server across the multiple networking equipment. Which enables
organization to host numerous operating systems in a remote location. Hence,
allowing users to possess versatility of location. Business which requires the
system to be online round-the-clock with a colossal number of users would
benefit from this virtualization. By dividing the network channels, the speed
of the network will be enhanced.

 

Hardware Virtualization – using the
software to create multiple hardware to perform like a single system (Traplin,
2012)

 

Storage virtualization – This type
of virtualization divides the logical storage from the physical storage, which
increases the versatility of managing the storage for users. This would allow
users to have freedom to store data from anywhere without the need to use a
physical storage device. The system would process the data and transfer it to
the physical location of the centralized system. This remove the need for
managing numerous different storage devices. There are three ways to achieve
storage virtualization; direct-attached storage, network-attached storage and
lastly storage area network.

 

3.      Describe
at least three functions that a Database Management System (DBMS) performs to
help create an accurate and consistent view of data throughout an enterprise.
Database management system (DBMS) has five main function; (1) data filtering
and profiling, (2) data integrity and maintenance, (3) data synchronization,
(4) data security and (5) data access (Turban, Volonino, & Wood, 2015).

(3) Data synchronization insure
information within the enterprise is consistent and properly managed. Data
synchronization also allow ease of managing data, there is only a need to
change the data at one location so that the change will be reflected across
enterprise. This is extremely helpful for enterprises with numerous branches.
For example, changing a customer data will ensure that changes made in that
location will be synchronized and updated in every network system of that enterprise,
therefore ensuring consistency and ensures that the information of the customer
is always up-to-date.

(2) Data integrity, DMBS also
guarantee that data are consistent by rejecting the user for order entry for
clients that does not exist. Therefore, not allowing them to commit fraud or
bypassing the system to gain personal gains. According to Tovar (2016), with
data integrity in play, it will ensure that all the data will be guarded and
not compromised.

Lastly, DBMS allows multiple
personnel to access the database. DBMS store data at a central location but can
be shared throughout the enterprise. To ensure that certain information is kept
confidential in the enterprise, the manager can also define the limits of
access in the DBMS system. This is a more consistent way to store data as
having multiple copies of the data will contaminate the information making it
obsolete or even inaccurate.
