Geoffrey Banks POS/355 Paul Rouk April 15, 2013 Distributed Systems According to Andrew Tanenbaum “A distributed system is a collection of computers that appear to its users as a single coherent system.” (http://www.cs.helsinki.fi/u/alanko/hj/K06/kalvokopiot/ch1_p6.pdf) Almost every current company uses distributed systems connected to servers and even larger databases. Each of these companies connects their organization and its information through local area networks also connected through server farms managed by administrators. Server side operating systems provide the server or database administrator to manage use on different computers that share information. We use distributed systems to not only make information …show more content…
The only problem with that is that it’s a temporary solution. The objective of business is continual growth. Therefore the system has to evolve and grow with the growth of the organization. Problems like these require quantitative solutions that are implemented meticulously. For instance, your software company is adding a quality assurance section to its database. It runs a server farm that supports a large development and production environment but a relatively small testing environment. Your responsibility is to integrate a new testing environment with new software testing tools and that supports a team of quality assurance testers. That systems growth would be exponential and require a project manager and business analysts to do quantitative research. Your stakeholder will need to know exact numbers of cost and how those implementations would support growth and increased output for the company based on projected growth. Another problem in all information systems is security. The larger the system the more users it supports the more opportunities for malicious intent. Organizations usually spend hundreds of thousands in training employees not to release business intelligence or try to exploit current systems for personal gain. Database administrators have to utilize a database’s database management system to set up privileged access to certain information on specific
Another reason for change might be some new technology that will definitely improve and help develop the business such
The distributed system defines, how the processes to communicate and gives data access for end client to the APIs which are used to manage the distributed data. Every distributed system have identified by communication protocol and address information.
A database administrator role in a company is vital to the future success. According to the Bureau of Labor Statistics, database admins use computer programs and special software to organize data, and turn it into information for its users. Of the three positions at Vigo, a database administrator requires the highest level of education, prior job experience and training. The responsibilities include protecting data from breaches, providing ease of access to users, and be able to work with management to create goals based off the data. The median annual income for database administrators is about $85,000. The projected growth is
Businesses have to adapt to the ever-changing economy. It is not much of a choice for business leaders to change elements of their organization to stay in competition with their peers. The hardest part, most of the time, is changing the people in the organization to develop the necessary outcome or goal. As a business leader getting rid of people or changing their job specifics is one of the many responsibilities they have to be comfortable performing. Organizations have to take into consideration their competitors, customers, shareholders, employees, and the community to make decisions. Change is an aspect that many people are afraid of. In the new millennium, organizational leaders have to embrace
Databases are the heart of the company. This is where all crucial company information is stored and can be accessed. Some databases are stored on site others in remote locations or using clouds. The information within a database can be manipulated in any way that the company needs it to be. Databases help to quickly search and retrieve information, it saves from data redundancy.
For example, let us consider an organization has branches in various locations and the organization has decided to store databases on one node or a central computer and to distribute them to local computers. The central node is the distributed database and it is a single logical database which is spread across different local computers and they are all connected over a network.
Moreover, now days using information system is not as walking as in the park, it has many new security treats that the company might lose their confidential data, financial and personal information.
In the Journal of Alcohol & Drug Education is the letter “Tapping into College Football: The Need for Research Examining the Impact of Stadium Alcohol Sales on Drinking Behaviors and Incidents” written to the editor by Adam E. Barry, Texas A&M; Steven M. Howell, Northern Illinois University; and Steven Salaga, Texas A&M University. Barry, Howell, and Salaga give background information on the alcohol sales and alcohol related incidents. They focus on the West Virginia University Case findings heavily. The research provided shows a decrease in alcohol related incidents in 2010 which was the year before allowing alcohol to be sold in the West Virginia stadium (Tapping into College Football). According to Jenni Carlson, a sports columnist for the Oklahoman, “West Virginia decided to start selling beer at concession stands in 2011. That was its final season in the Big East before jumping to the Big 12. The first year that it sold alcohol in the stadium, sales added $700,000 to the athletic department coffers. But there were more benefits, benefits that should interest other schools. In 2011, the campus police at West Virginia reported an across-the-board drop in game-day incidents. Calls. Cases. Arrests. Charges. All of them went down, including a 35 percent drop in arrests,” (Cheers to Selling Beers at Football Games).
Second, Database is needed to take the collection of all sorts of sensitive data to organize, analyze, and extract data. It is the heart of many functions in today’s world. For example, when a password or user in a program it is checking the information type in against the information it stored in order to open the software. Databases solve most of the data management problems that are encountered.
That means that with the network operating system we can have lots of users all concurrently using resources on our serve.One of the most important aspects about server operating systems is the security. Workstation OS provides great security for end-users, but it's still not as tight as the security offered by the network operating systems. The reason for that is that with the network operating system were providing services to hundred or thousands of concurrent users. Therefore security is critical Workstation operating systems also provide some type of authentication by using user names and passwords which reside on local database on the local
Pyramids, Pharaohs, dynasties; what do these characteristics have in common? These characteristics represents the Egyptian culture. Egypt is known for its famous pyramids and rulers.

Driving under the influence has affected many people's lives and families. Today I would like to talk to you about the problems of drinking and driving, and why it is a concern for all of us. Driving under the influence is one of the most common and dangerous situations you can put yourself or someone else in. The fact is that drinking and driving is a huge deal and can leave a long trail of broken dreams and hearts. If you drink and drive, not only are you putting yourself at risk, but your passengers and the pedestrians outside of your vehicle. According to the most recent statistics by the National Commission Against Drunk Driving states that 17,000 Americans die each year in alcohol- related traffic crashes and 600,000 Americans
Change is inevitable. Changing is not always welcomed but it is necessary for organizations to maintain their place in the world. Successful organizations thrive because they have a vision, a mission
It is generally accepted that information is a vital commodity for the successful operation of today’s organizations. Nowadays modern business organizations are using computerized information systems in order to obtain such information. However as the technology advances rapidly the main issue is how can an organization should effectively use such an information system - which its management sometimes can be unpredictable - in order to effectively help the whole organization structure to improve and take the most out of it.
Database security is vital for any and every organization which uses databases. Without proper security, the databases can be breached and the breaches can lead to confidential information being released. This has happened to many organizations whether they are large or small; for example, in the past few years Target and Sony both fell victim to database breaches. To make matters worse both Target and Sony were actually warned about the flaws in their security, but neither took any action to resolve the flaws. Looking into these breaches and how they were handled could lead to designing better databases. Organizations should also look within themselves to assure all employees know good security practices. Simply following regular procedures such as installing antivirus software and firewalls can help create more secure databases. An organization should look at all of their databases to ensure the same top level security is established for all of their databases.
