1. Thecourse textbook states that “most business initiatives succeed or failbased 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 whenthe data that is collated does not meet standards or when the data lacksinformation which may benefits the enterprise.One of the main reason thatorganizations or enterprises have information deficiency issues is due to thethat there is a vast amount of data available, therefore there is a difficultyfor the organization to pinpoint which data provides the proper information.Moreover, if there is no standardization of data available, one will find it anissue to isolate the correct data, there will only be a good data or a betterdata. Secondly, the data available to the organization are not sorted out intable format which allows better comparison. Imagine attempting to compare thedata in a random alignment, without a table, it will be easy for human error tooccur. Therefore, infrastructure is implemented to help process datacollection, however the collection of data must be in place from the beginningof the start of the enterprise for the infrastructure to work. Another reasonthat most organization have information deficiency is due to some of theworkers in the organization which keeps personal copy of the database, thesewill lead to them changing their personal copy of the data instead of thedatabase system provided by the company. This will lead to the inaccuracy ofthe data, as any changes should be updated in the database system at once.
Lastly, enterprises require large amount of financial funding to enhance theirinformation technologies, and such technologies is not cheap and therefore someenterprises might be running on a more obsolete database which might have flawsor bugs (Sutcliffe and Weber,2003). 2. Hardware virtualization is a widelyutilized technology in the business world for purposes of reducing energy andproviding scalability with load-balancing. Describe three major types ofvirtualization utilized by businesses.Answer: Network virtualization – Thisvirtualization allows the server to operate like several servers by tasking asingle server across the multiple networking equipment.
Which enablesorganization to host numerous operating systems in a remote location. Hence,allowing users to possess versatility of location. Business which requires thesystem to be online round-the-clock with a colossal number of users wouldbenefit from this virtualization. By dividing the network channels, the speedof the network will be enhanced.
Hardware Virtualization – using thesoftware to create multiple hardware to perform like a single system (Traplin,2012) Storage virtualization – This typeof virtualization divides the logical storage from the physical storage, whichincreases the versatility of managing the storage for users. This would allowusers to have freedom to store data from anywhere without the need to use aphysical storage device. The system would process the data and transfer it tothe physical location of the centralized system. This remove the need formanaging numerous different storage devices. There are three ways to achievestorage virtualization; direct-attached storage, network-attached storage andlastly storage area network. 3. Describeat least three functions that a Database Management System (DBMS) performs tohelp create an accurate and consistent view of data throughout an enterprise.
Database management system (DBMS) has five main function; (1) data filteringand profiling, (2) data integrity and maintenance, (3) data synchronization,(4) data security and (5) data access (Turban, Volonino, & Wood, 2015).(3) Data synchronization insureinformation within the enterprise is consistent and properly managed. Datasynchronization also allow ease of managing data, there is only a need tochange the data at one location so that the change will be reflected acrossenterprise. This is extremely helpful for enterprises with numerous branches.For example, changing a customer data will ensure that changes made in thatlocation will be synchronized and updated in every network system of that enterprise,therefore ensuring consistency and ensures that the information of the customeris always up-to-date.(2) Data integrity, DMBS alsoguarantee that data are consistent by rejecting the user for order entry forclients that does not exist.
Therefore, not allowing them to commit fraud orbypassing the system to gain personal gains. According to Tovar (2016), withdata integrity in play, it will ensure that all the data will be guarded andnot compromised.Lastly, DBMS allows multiplepersonnel to access the database. DBMS store data at a central location but canbe shared throughout the enterprise.
To ensure that certain information is keptconfidential in the enterprise, the manager can also define the limits ofaccess in the DBMS system. This is a more consistent way to store data ashaving multiple copies of the data will contaminate the information making itobsolete or even inaccurate.
