Data

A New Look on Displaying Stock Data {1}

by Alexander H
Interpreting the information that is relayed on the stock market can be a daunting task for any user. A screen full of numbers and arrows may be difficult for many to extract the information they need quickly. However, the StockTouch app is aiming to change the way stock data is visualized by streamlining the most important elements of the stock markets into one interface that almost any user can utilize efficiently. An article by Allisa Skelton provides a solid overview of the features this program and how easy it is to navigate. As described, the app covers “nearly 75% of all global trading activity” and displays 50,000 tiles that are organized into “colorful squares”. The green colored tiles represent stocks that are gaining in value while red tiles convey losses. In addition, the user can tap on certain stock regions, and then tap on a specific stock to show a “statical graph, information on the stock, and links to news articles about the stock”. The experience is so streamlined that the company claims that “StockTouch tells you more in five seconds than you would learn reading financial news today.
In relation to the subject of database, Chapter 1 illuminates the importance of utilizing information in such a way that it is beneficial to users and managers. When most users access stock information, they are bombarded with a stock ticker slowly spitting out numbers and scrolling across the screen. Being a more visual person, it becomes intimidating to see various streams of numbers and information that is irrelevant to me. This application seeks to generate a new way of visualizing stock information so that it is more applicable to users. The main idea behind this application is to allow users to access relevant information quickly and obtain a snapshot of the stock market just as fast. In this modern day, users live a fast paced lifestyle and want to be able to obtain the information they need swiftly and can therefore utilize this app to keep track of their investments and trading activities.
By providing multiple graphical displays, the user can perceive various levels of the stock market in an easy to use interface. Therefore, decisions can be more readily made and the stock market climate can be easily gauged. Any experienced stock trader can vouch the importance of being able to view the stock market quickly and utilize the right timing in order to gain maximum stock value. This method of graphically representing stocks is streamlined to maximize stock decisions and provide all the tools a trader needs to make educated decisions. StockTouch’s innovation enlightens that data historically presented in usual manners can still be altered and enhanced in new ways that can actually raise the bar on understanding and perception of information. read more...

Megaupload Cloud Data {3}

by Mike Y

Dvorak’s article talks about the seizure of Megaupload’s domain and website by the U.S. government and the negative effects to the movement of cloud computing. The data in the servers still exist but is planned to be deleted but has not yet happened as of March, 23, according to Information Week. The problem, stated by Dvorak, is that there were 50 million users held by Megaupload and contacting every single one of them would be impossible. The reason this is so bad for cloud computing is because it create uncertainty in the objective of cloud based services. It would not be used if any cloud based service could be taken down or deleted on the federal government’s wim. Cloud computing is relevant to our class because it is the current trend in the IT industry and web based services. Currently, there is a site for social networking, one for pictures, another for video, and many other sites to fill consumer needs. Eventually, it will be condensed to one single site in the place where it used to take many sites to fulfill user needs. As hardware becomes more powerful and less expensive, websites can charge for premium services or even be free. As the features of websites increase, so will the competition between websites offering similar services. I believe cloud computing is the future. At first I was skeptical of the services and had many questions. How reliable is it? How much down time? How long will my data be there? My mind was completely changed when I used Google Docs. In an age where individuals have multiple points of online access, the convenience cloud based services is almost a requirement. Having a single access point for files is very user friendly. There is no need to need to make sure every laptop, phone, or desktop has all the same and updates files; it’s all in one place. Of course, secondary and local backups should be made for important files as no service is 100% is reliability.

What is the Cloud? {2}

by Nelson T
In an article that I have read from PC Magazine Online, cloud computing is the next big thing coming to consumers and businesses. Cloud computing allows people to have complete access to their personal data as well as data from other users as well. This is called Personal Cloud Computing. An example of one of the many benefits of the personal cloud is automatic sync. If a user searches for music using their mobile device, purchases a piece of music from their favorite artist, the mp3 file downloads not only on their mobile device but also downloads automatically to their home computer and other devices that are linked that cloud account. Other items include the user’s address book, email and documents.  Having access to the cloud is fairly cheap and this is attracts business. Businesses can use the cloud to do some serious data mining on the fly. Having access to information coming from their users. A way that a cloud can be distinguished is from key attributes such as it being from a third party vendor that is usually off site, accessed over the internet, minimal IT knowledge are a few attributes. Cloud computing is very useful for a connected consumer and for the success of a business. As an owner of an Apple iPhone, I am a user of their cloud service named iCloud. I find this service to be very useful. Just like my example from earlier, anything i do on my mobile smartphone is sync automatically to cloud servers and then pushed to my laptop and other devices that are connected to the iCloud service. I have personally realized the benefits of this service and its been great since the start. I rely on it almost everyday to make sure I get what i need from anywhere I am connected. read more...

Big Data helps drive Math Ph.D.’s to IBM {Comments Off on Big Data helps drive Math Ph.D.’s to IBM}

by Hassib K
IBM is the largest employer of mathematics Ph.D’s in the nation.  They hire alot of mathematicians for help with analysis of big data.  They develop proofs that take anywhere from 2 months to some times 2 years.  The one for an US based oil company took 2 years and then allowed them to open up 24 additional sources of income, so it was well worth the effort.  IBM finds that mathematics and statistics Ph.D. holders tend to have the analytic and quantitative skills they’re looking for these days.  The push towards big data is driving alot of this demand for mathematicians.  Having huge of amounts of data to analyze will require someone who is comfortable with numbers, and this is clearly the mathematicians habitat.  Steve Mills, a senior vice president “We are the largest employer of Ph.D. mathematicians of any company in the world,” (Thibodeau, 2012).  A researcher on the topic recently said that he even sees grocery stores hiring more mathematicians, so it’s definitely a field to consider. read more...

Data is Power {1}

by Cole O’C
Since we are looking into linking database with websites via ASP.NET, and Google just consolidated their database for all their users, I thought it would be worth talking about. Last Thursday, March 1, Google removed the barriers that legally stopped them from linking all of a person’s electronic data together. Before, it kept things separately, such as your Google searches, the videos you have watched on YouTube, where you have gotten directions to on Maps, and so forth. Now, all of that data is mingled together in order to let Google sell you what they think you most want. “If you watched football clips on YouTube, an ad for upcoming matches might appear beside your [Gmail] inbox.” This gives Google a tremendous amount of power over the web experiences of literally countless amounts of people. One of the largest concerns to crop up since these changes is, “What if Google got hacked?” It is now safe to assume that every intelligence agency in the world wants access to the Google data servers. The amount of information that Google has in its servers is completely ridiculous, but in and of itself is not worth a cent more than the servers storing the data. Using data correctly is a staple of being a successful business in the modern world, no matter the amount of data available. read more...

MIS Wars II: Attack of the Data {2}

by Brian T
A recent PC Mag article I discovered discussed information management systems and the plight of data storage/manipulation for today’s IT field.  The study cited stated that data volume is currently increasing at approximately 59% per year and that it costs companies triple the amount to store data as it does to attain it. The study analyst Mark Beyer asserts that “unstructured data” (data content) goes largely ignored despite it’s majority presence in organizations over structured data. He then goes on to say that information overload cannot be possible and it is up to those IT professionals to maintain control. Mr. Beyer also believes that there are 12 “dimensions” regarding the upkeep of data upon entering the 21st century’s information challenges: Perish-ability, Fidelity, Validation, Linking, Classification, Contracts, Technology, Pervasive Use, Velocity, Volume, Variety, and Complexity. (To see the appropriate logic regarding these dimensions, see the figure in the article). read more...

Government Data Quality {1}

by Mike Y

            The Information Week article goes into the Open Government Directive which “requires federal agencies to take steps to improve data quality.” The directive not only improves quality, but also the objectivity, internal control, and accountability for financial data in agencies. Every agency will have to designate a high-level official that will oversee the directive. It is also believed that having accurate data will improve government efficiency. read more...

This app is also available  for the ipad/iphone. read more...

What to Expect in Data Warehousing {2}

by Penny P
Data warehouses play a critical role in corporation/institutions. They allow users to quickly retrieve data to be used for data mining or for data analysis tools. The results that they get from these tools are then used to support business decisions that would be made. The authors of the article designed a case study that would help beginners understand the basics of data warehousing. Using the enrollment data from Universities, the main objective was to prepare the data for a mining system that would be used for predicting student enrollment. read more...

Data Types {2}

by Jamal A
The article I read talks about the most important contemplations of selecting correct data types when designing a SQL Server database. It talks about how choosing a correct data type in the database design phase can have a significant impact on the efficiency and performance. According to the article, the SQL Server offers six sets of data types. First and formost commonly used data types that stores numeric information are called “The Exact Numeric Data Types” that includes: int, decimal, and money.  The next data type is called “The Approximate Numeric Data Types”, this data type are not as commonly used as the exact numeric data types. The approximate numeric data type includes: float, and real. Moving on, the next data type that is mentioned in this article is called “Date and Time Data Types”, this data types allow designers to easily work with time zones. After that, the next data type in the category is called “Character String Data Types”, it is used to store text values in Microsoft SQL Server databases, and this includes: char, nchar, varchar, nvachar, and text.  The next data type that is mentioned in this article is called “Binary Data Types”, it allows DBAs to store any type of binary data, this includes: bit, binary, varbinary, varbinary(max), and image. Finally, the last data type that is mentioned in this article is called “The Other Data Types”, it includes: cursor, sql_variant, table xml, and uniqueidentifier. read more...
