It is the process of using data to understand different things, to understand the world.

Data science is the art of uncovering the insights and trends that are hiding behind data. You can say its like storytelling to generate insight. And with these insights, you can make decisions for a company or an institution. “Data science is a field about processes and systems to extract data from various forms of whether it is unstructured or structured form.” 

Data science has always fascinated me before I even knew what it really was. I would see my elder brother work with data and analyze it with such ease that it would look like magic. How could one deal with such a large data so easily?

Now why do we need Data Science in today’s world?

In the past, the data that we had was mainly structured and small in size, which could be analyzed by using the simple analysis tools. But today most of our data is unstructured or semi-structured (More than 80% data is unstructured.)

Dealing with huge amount of unstructured data has only been possible due to data science and has helped in so many other real life applications such as understand the precise requirements of your customers from the existing data like the customer’s past browsing history, purchase history, age and income and build recommendation systems accordingly; weather forecasting using the data from ships, aircrafts, radars, satellites which can be collected and analyzed to build models that could help in predicting the occurrence of any natural calamities and help save many precious lives.

The above examples are just the tip of iceberg. Data science is used in a ton of other applications and has made life so much easier. No wonder the majority of students oday aspire to be a Data Scientist.

This is an example post, originally published as part of Blogging University. Enroll in one of our ten programs, and start your blog right.

You’re going to publish a post today. Don’t worry about how your blog looks. Don’t worry if you haven’t given it a name yet, or you’re feeling overwhelmed. Just click the “New Post” button, and tell us why you’re here.

Why do this?

• Because it gives new readers context. What are you about? Why should they read your blog?
• Because it will help you focus you own ideas about your blog and what you’d like to do with it.

The post can be short or long, a personal intro to your life or a bloggy mission statement, a manifesto for the future or a simple outline of your the types of things you hope to publish.

To help you get started, here are a few questions:

• Why are you blogging publicly, rather than keeping a personal journal?
• What topics do you think you’ll write about?
• Who would you love to connect with via your blog?
• If you blog successfully throughout the next year, what would you hope to have accomplished?

You’re not locked into any of this; one of the wonderful things about blogs is how they constantly evolve as we learn, grow, and interact with one another — but it’s good to know where and why you started, and articulating your goals may just give you a few other post ideas.

Can’t think how to get started? Just write the first thing that pops into your head. Anne Lamott, author of a book on writing we love, says that you need to give yourself permission to write a “crappy first draft”. Anne makes a great point — just start writing, and worry about editing it later.

When you’re ready to publish, give your post three to five tags that describe your blog’s focus — writing, photography, fiction, parenting, food, cars, movies, sports, whatever. These tags will help others who care about your topics find you in the Reader. Make sure one of the tags is “zerotohero,” so other new bloggers can find you, too.
