Each day, 2.5 million TB of data are generated. This huge quantity of data needs to be stored so that they can be easily accessed later. They are data measured in zettabytes, petabytes and exabytes, which are lesser known terms.
As companies gather rising amounts of data, requirements on infrastructure and technology have become larger. The following 3 Vs describes what Big Data is all about.
Volume
This feature represents the absolute amount of data produced by companies. It includes data from transaction information, social media created information, sensor and machine to machine data. Without technologies to accumulate such large amounts of data, storing it easily would be a problem.
Velocity
Latest technologies allow faster data processing through sensors, RFID tags and other technologies. However, structuring and storing them in real time is a big challenge.
Variety
Data come in a wide variety of formats. It can range from regular databases, unstructured video, audio and email to transaction data.
These three features of Big Data offer a challenge for the companies that need to store data in an integrated, structured, affordable and accessible way.
Social media assure the growth and development of innovation through mass collaboration. Across various industries, companies use social media platforms to promote products and services. They also use it to observe how people respond to brands.

One of the largest Big Data experts is Facebook. It deals with petabytes of data on a regular basis. As the world connects through this platform, it generates algorithms to track those connections.
Whether it’s a wall post or your favorite movies and books, Facebook surveys each and every bit of your data. It does this to provide you superior services each time you log in.
There is a variety of technology working behind this platform. Below are the most significant ones:
Facebook manages the biggest Hadoop cluster. It has beyond 4,000 machines and stores millions of gigabytes. This large-scale cluster provides some crucial skills to developers.
The developers can openly write MapReduce programs in any language.
SQL has been combined to process large data sets, as the majority of data in the Hadoop’s file system are in table format. Because of this, it becomes easier for developers to access smaller SQL subsets.
Beginning with searching, recommendation system, log processing and data warehousing, Hadoop is enabling Facebook in any way possible. In fact, its first user-facing app, Facebook Messenger, is based on Hadoop database.
Encountering a large amount of disorganized data each day, Facebook realized that it requires a platform to speed up its analysis. It developed Scuba to help the Hadoop developers plunge into the massive data set. It also allows them to carry on an ad-hoc analysis in real-time.
Facebook wasn’t meant to run across different data centers. A single malfunction could cause the whole platform to fail.
Scuba enables the developers to store in-memory data in bulk. It’s supposed to help speed up the informational analysis. It executes small software agents to collect data from data centers and compress them into log data pattern. The compressed data are further compressed by Scuba into smaller memory systems which can be promptly assessed.
After the launch of Hadoop by Yahoo for its search engine, Facebook also decided to empower its data scientists. It needed help in storing huge amount of data in the Oracle data warehouse. Thus, Hive came into existence.
This tool enhanced the query capability of Hadoop by using a part of SQL. Eventually, it became popular in the unstructured world. Nearly thousands of jobs are running using this system today.
As Facebook doesn’t run on multiple data centers, it needed the help of Prism. It’s a platform that brings out several namespaces. It helps in developing many logical clusters, too.
It was getting difficult to manage the task trackers and cluster resources. As pull-based scheduling model was causing a delay in handling small jobs, MapReduce came to existence. Hadoop was restricted by its slot-based resource management model. It wasted the slot every time the cluster size was unable to fit the configuration.
Developing and executing Corona helped in establishing a new scheduling framework. It helped distinguish resource management from job coordination.
Today, Facebook has become one of the substantial corporations in the world. It’s all thanks to its considerable data on over 1.5 Billion people on earth. However, security and privacy concerns remain as it isn’t sure whether Facebook will just save its big data on its server or use them in order to make money.
But, one thing is for sure. It’s the Big Data that pushed Facebook, a small-time startup in Harvard, into becoming one of the large corporations of all times.

Music has been with us since prehistoric times in one form or another, growing with human society and culture, and taking new shapes one century after another. Humans have become so accustomed to it that listening to music has become second nature. We take music in our lives so much for granted that we rarely stop to think how it influences our mood or daily actions.
For example, did you know that listening to music at the office can make you more productive?
Here’s how.
Listening to music is not an activity reserved for free time and parties only. In fact, according to the latest surveys, more than half of employees listen to music at work.
Compared to people who do not listen to music, those who do are 90% more productive and, more than that, they provide more accurate work. The habit of listening to music at the office isn’t looked down upon by managers either. Around 77% of them agree that music gives employees a morale boost and almost half believe that it improves their performance in sectors such as sales.
Scientific studies back up what people already instinctively know: music influences the human brain. When listening to music, multiple areas of our brains are activated. This includes the motor cortex (responsible for movement), the nucleus accumbens, amygdala, and cerebellum (responsible for stimulating emotion). The hippocampus (stimulates memories), Broca’s and Wernicke’s areas (language processing) also get stimulated.
When listening to music, the brain releases dopamine, the same chemical released when we eat our favorite food. Apart from making us feel pleasure, dopamine also improves focus. Which leads us to…
Listening to music is a powerful productivity tool. Whether you have an office station or you just put on your headphones, once you hit play, you are bound to work better, faster and make less mistakes. Music helps you focus, blocking external distractions and allowing you to tackle difficult tasks with more motivation. In addition, your favorite tunes can also reduce stress and anxiety. So, for example, if you are coping with personal issues, music could protect your work performance.
Those who work in a challenging, stressful office environment can keep things under control by listening to music. Music produces the same amount of relaxation as a massage, so this is the simplest way to reduce anxiety and overcome negative emotions.
Aside from using music to increase productivity, scientists also say that this activity can increase memory. It’s one of the main reasons why students are constantly recommended to study for exams while listening to music.
The benefits of listening to music at work don’t just apply to the office environment. Workers in just about any field can benefit from these effects.
Apart from boosting performance and productivity, listening to music has been scientifically proven to offer additional health benefits, including:

Apart from these, several studies have also suggested that listening to music while eating could make people consume smaller food portions and have increased blood flow. However, more research is needed.
Not all music influences you in the same way. Some genres are recommended for certain office activities:
• Ambient music seems to be the most effective. According to research, it improves focus, so it’s perfect for tasks that require attention to details, such as data entry. Ambient music is quite neutral, so it doesn’t distract you.
• Pop music is happy and upbeat, so it makes you work faster. One study showed that people who were listening to pop music while doing data entry were 58% faster. Pop music also reduces mistakes by 14%.
• Dance music also helps you work faster, but not just in data entry. For example, if you have a proofreading task, you can complete it 20% faster by listening to dance beats.
• Classical music has a great impact on work accuracy. Pick a classical radio station and your work will be 12% more accurate!
Of course, these are just general studies about the influence of music genres on productivity and results may vary depending on what kind of music you normally listen to. Broadly speaking, scientists recommend workers to listen to music without lyrics if they are doing something that involves linguistic processing. Otherwise, lyrics will become a distraction.
Also, while discovering new music is always fun, the workplace is probably not the best place to explore songs. Discovering new music interferes with your ability to process new information. For improved performance and focus, scientists recommend that we stick to familiar songs we know and love.
