  • The owner of a company looks over your design and sees that you are using database centralization. He questions why you would do this since it violates the rule that data should be managed and stored in close proximity to its users. Explain to him your reasoning for using database centralization.
  • Explain whether and why you feel that the rule is important or outdated

To improve data preservation

Centralized database storage improves data preservation. PC computers and laptops rarely offer fault tolerance -- the capacity to continue functioning after hardware failure. Fault tolerance requires duplicate components, which drives up costs. The lack of fault tolerance places any data stored only on a PC or laptop at risk for permanent loss. Centralized storage often includes a fault-tolerant setup and redundant storage that preserves the data, even in the event of a catastrophic hardware failure in a hard drive.


Locally stored data represents an ongoing physical security risk. Laptops and notebooks get lost or stolen. An unattended PC presents an opportunity for anyone to access, steal or damage locally stored data. Centralized database storage and proper server room security restrict direct physical access to a single location and a small group of people.
Improves Data Security
As businesses now maintain vast quantities of sensitive consumer information, data protection is a mission-critical issue. Providing data security with central database storage creates fewer challenges than ensuring data security across multiple local storage sites. Data access policies limit the damage one compromised computer can do, as does implementing encrypted virtual private networks, firewalls and rigorous password protection.
Reduces costs 
Centralized storage requires the business to invest heavily in the server technology, such as fault tolerance, but also allows it to cut overall costs. The maintenance to the central server proves less costly than maintenance to multiple computers, especially if the business operates in multiple locations. Centralized storage also reduces overall space requirements for data storage and processing.

conclusion

The centralized systems thrive on the use of authority. The concept of authority and subjugation inhibits the treatment of all humans as equal, which is against the principle of a truly democratic system. These systems emphasize the vertical relationship and weaken the horizontal ones. Consequently, the mutually-beneficial communication and collaborations among local authorities do not exist. On the contrary, distributed systems operate inherently in the principle of justice and equality of all. And this has been the ultimate goal of democracy, which in-practice has ironically been ridiculed by most of the existing systems in the world.
