Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

1. Identify the area of impact the scenario relates to. Business 2. Identify all ITGS terminology and phrases (IT and social/ethical). Botnets, worm, malware, 3. Describe one ITGS social/ethical concern in the article. Security is the main issue in this article since it is dealing with worms, which infects and damage computer files. 4. Describe the relationship of the main stakeholders to the IT system. The main stakeholder, Facebook, is combating Koobface worm, which is, a malware (malicious software) to prevent it from infecting its users PC. 5. Explain the relationship between the IT system and the social/ethical issue identified in question 3. Koobface worm is a malware that could infect Facebook's users' computer, which is a security issue. It is estimated that the group earned more than $2 million from June 2009 to June 2010 by delivering the victims of its worm to unscrupulous marketers and makers of fake antivirus software. 6. Discuss at least one problem that relates to the impacts of the social/ethical issue. A Koobface attack starts with an invitation to watch a video and a message about updating the computer's Flash software. Clicking to get the update begins the download of Koobface, which gives criminals control of the computer, while the worm tries to spread itself further through the victim's social network contacts. This is a security breach to Facebook's users computer. When the criminals have control of the computer, they can do anything they want with it like, stealing personal information, etc. 7. Evaluate one solution that addresses the problem identified. Facebook need to step up their security for their users safety. To halt Koobface, Facebook uses algorithms that can detect suspicious posts and hijacked accounts, looking for unusual behavior like log-ins from odd places and a surge in messages sent. Facebook also keeps a blacklist of malicious Web links to prevent them from being shared on the site. When Koobface posts find a
