Vs of Big Data

Vs of Big Data Big data based on the word itself means data which is big but how much big is considered as big? For a small business, big data might be few gig while Facebook processes 100s of Tb data every day [6]. So, the definition of big data will slightly differ from organization to organization. Few years back big data meant the huge size of data which is beyond the ability of normal software to process and handle it. Big data was defined using the 3 Vs : Volume, Velocity and Variety but now that has changed and now four more Vs were added which consists of [1] : Variability: This means the data does not have same meaning every day and is constantly changing Veracity: Making sure the data we have is accurate Visualization: Visualizing the data so it can be easily interpreted by readers Value: The final goal is to get some value out of data University of California, Berkley asked forty thought leaders in data science field about the definition of Big Data. John Akred the founder and CTO of Silicon Valley Data Science described big data as, Big Data refers to a combination of an approach to informing decision making with analytical insight derived from data, and a set of enabling technologies that enable that insight to be economically derived from at times very large, diverse sources of data [5].While David Leonhardt who is an editor for The New York Times defines big data as, Big Data is nothing more than a tool for capturing reality just as newspaper reporting, photography and long-form journalism are [5].ÂÂ   As we can see different people from different industry has different definition of Big Data but one thing in common is that it follows the basic three Vs defined before and the end product is different. Microsoft defines big data as patterns which can be used with proven practices for predictable results. Further they defined big data as Data often produced at fire hose rate, that you do not know how to analyze at the moment but may provide valuable information in future [4]. Then they ask the readers if they know what the visitors to their website are really thinking? Or if they are business owners and if they know what the customers think of their products? They ask these questions and then tell them that the answer is hidden in the pile of data which is hidden away and if you can find it still it might be difficult to process it and get meaningful insights out of it. Microsoft then further defines big data as Big data typically refers to collections of datasets that, due to size and complexity, are difficult to store, query, and manage using existing data management tools or data processing applications. We notice here that they are trying to focus on the difficulty of storing, querying and managing data and can expect a solution or product for it. So basically, Microsoft is trying to connect with their readers by asking them if they have a big data problem and then providing an example of what techniques data analysts and business managers are following and how Microsoft can help them. Then they describe Big Data with the text book definition using the three Vs and links the readers to their product called HDInsight [4]. HDInsight is a Hadoop- based solution which Microsoft offers. It is an all in one solution which can store data, process data and executing data analysis. Tableau is one of the biggest company and provider of visualization techniques which can help companies visualize data from any source. They define big data as structured or unstructured, petabytes or terabytes, millions or billions of rows, you can turn data into big ideas[1]. They try to focus on the visualization part as Tableau is used discover and understand their data. So, if we compare it to Microsoft definition they are missing the part about storing the data, retrieving it and the problems behinds it.ÂÂ   While explaining the meaning of big data tableau keeps pointing out the importance of visualizing the data regardless of the size of data and how organizations can leverage this to their benefit. They also iterate that storing, preparing and iterating data is costly and Tableaus vision is to help companies apply best practices to get the most out of their data. SAS uses the three Vs of big data (Volume, Velocity and Variety) to define it and say its not the amount of data that is important but what to do with it and how to use it to make better decisions. SAS adds two more dimensions Variability and Complexity to its definition of big data. They define variability as inconsistency in the amount of data that flows which cannot be controlled [3]. Complexity is defined as different types of data coming from different sources and connecting and combining it to get meaningful insights out of it. When we compare, the definitions provided by these companies it is obvious the core definition of big data remains the same but then these companies tailor tit according to the products they offer. Microsoft which provides end to end solution for big data talks about storing of data which is skipped by Tableau as it provides solution for visualizing the data and not storing. So, we can conclude that there is no authority on the exact meaning of Big Data and its solutions. Works Cited [1] Understanding Big Data: The Seven Vs. Dataconomy. July 23, 2014.

The Act of Blogging:Creating an Online Home :: Blogs

The Act of Blogging:Creating an Online Home A phenomenon has taken place on the internet. This phenomenon is called blogging. Blogging is nothing more the journal of people published on the internet. The interesting thing is, other people around the world can share in this journal with you. Another interesting note that might be commonly over looked, is the resemblance of a blog site and a real home, metaphorically speaking. Whether or not a blogger is intentionally giving his site a homely look to it, the resemblance is there nonetheless. Items you might come across on a blog site are pictures, a portfolio of the blogger, and links to other blog sites. For the bloggers that take this seriously, it is important to have this information to create an environment that you are comfortable with and you are comfortable with others to view. You want for the viewers to feel welcome to your site and enjoy what they see and read. For the viewers, they are looking for a connection with other people with similar likes and dislikes. An individual named Andy does a lot of traveling, and has created a blog site to tell about his travels. Because of his extensive travels, Andy has chosen to make an online home. In several e-mail conversations I had with Andy, he told me that his web site is a place where he can go for some familiarity. He was intrigued at the comparison that I had made between the two types of homes. When you enter this site you are greeted with a different picture about once a week. Pictures are important; they add life to the web site. Pictures are also important because they give character to the web site, and in some cases can even tell a story. Pictures on a web site are a lot like pictures on the wall of a house, for the same reasons. Pictures or paintings I feel are a necessity for a house or web site. Throughout a house you will find books, magazines, newspapers, and all sorts of other little nick nacks. These items are there for enjoyment and education. They also describe what kind of person it is that lives there and what his likes and dislikes are. In the blog world, you might find a personal profile of the blogger. For the serious bloggers, it is almost a guarantee that you will find one.

Womens Place in Our Society

Today women are enjoying high place in our society because Islam has given them great respect. In the near past women were considered inferior to men. They were debarred from taking part in social life. Their sphere of activities was limited to domestic work. Up to the 19th century it was believed that women were the servants of the homes of their husbands. In those days women were not allowed to take part in political and social life and administration.Rousseau the French philosopher who never married once said The dignity of woman consists in being unknown to the world her glory is the esteem of her husband her pleasure the happiness of her family. Quite recently women have come to take more and more prominent part in many spheres of life In some respects they have excelled men. In sports intellectual and artist pursuits in office and industry they have set a new record of honesty and efficiency.They have succeeded marvelously as teachers and nurses goldsmith the famous poet and wr iter made a complaint two centuries ago Women famed of their valour their skill in politics or their learning have left the duties of their own sex in order to invade the privilege of ours. This is what the women are doing today. Now women are enjoying that place in society. Which they could never think of it past. There is particularly no field where women are not competing with men. In professions outdoor life and law they claim equality with men.In business trade industry in the learned professions in politics administration, scientific research literary and artistic activities. Eve is making herself felt everywhere. They are police and military officers. They are working as sale girls as air hostesses and as clerks and steno typists. They are turning out men from the posts of personal secretaries. As the days pass we have to get more and more used to the idea of seeing women working side by side of men riding driving, flying, playing even fighting. Even in Pakistan we have women athletes writers, leaders, administrators.They are fast discarding purdah and taking to active outdoor life. Law has given a woman a status equal to that of man. In nearly every democratic country women have the right to vote. Not only this now women got a chance to become the head of he state. The selection of Benazir Bhutto as Prime Minister twice in a great example of women's place in society. Many other women are also serving at key posts. Many thinkers including most of the Muslims do not like their idea of woman liking an active part in public life and in the professions.They argue that biologically woman's function is different from man's she has to be a mother. Women are not suitable for every job. They are too delicate to perform arduous duties of life. The real greatness of a woman lies in her role as mother. It is rightly said the hand that rocks the cradle rules the world. The mother who can bring up the right sort of children is really a great benefactor of society. Is lamic society gives a very respectable position to woman. The Holy Prophet has said â€Å"Verily the paradise lies under the feet of your mother†.

Stress and Its Management - 1857 Words

Stress Introduction Zajacova et al. (2005) state that stress refers to the non-specific response of the body, to anything that makes a person feels threatened or upset. Stress prepares the body to meet situations which are tough with focus, stamina and strength. It can be caused by positive or bad experiences. Stress is provoked by events called stressors. There are two kinds of stress. Negative stress (distress) and positive stress (eustress). Eustress affects our activities in a positive way (Striker et al., 1999). It is a short-term stress which increases the bodys strength immediately. Positive stress affects us during periods of physical activity, excitement or creativity. It motivates and inspires a person to finish a certain task and also helps one think critically towards an assignment (Spector, 2002). Negative stress is the most popular type of stress. It arises when the normal routine of the body is altered. It causes negative effects such as anxiety, depression, fatigue and unhappiness. When a person is distressed, the body becomes unable to return to a relaxed state even when the stressors are absent. Physical stress comes about when the body responds to physical stressors such as work, exercise, noise, or an illness (Ritchie and Brindley, 2007). Psychological stress refers to an emotional experience where the mind perceives the inability to cope with a problem.
