Let us start with finding out the answer to the question, "what is Data Science?"

What is Data Science? #

Data science is the discipline that uses the scientific methods, domain expertise, algorithms, knowledge of math and statistics to extract meaningful insights from data.

The emergence of new technologies has resulted a huge increase in data. This has provided an opportunity to analyze this data and derive a meaningful insights from it.

Analyzing such data requires some special experts like Data Scientist, who specializes in Data Science. These Data Scientists use various statistical and machine learning tools to analyze the data drawn from different sectors like social media, e-commerce sites and Internet searches, etc.

Therefore, we can understand Data Science as the study that involves extracting meaningful information from large amount of data using various scientific methods, algorithms and processes.

Why do we need Data Science? #

Now that we have understood what Data Science is, let us discuss why Data Science is important.

Today, Data Science has become a significant factor for the organization’s growth. It helps them to make a better decision to enhance their business.

Organizations with the help of Data Scientists derive the meaningful insights from large amount of data that allow them to analyze themselves and their performance in the market.

Data Science helps the organization to understand its customer requirements better and provide them good service that will help them to grow efficiently.

As more organizations are implementing Data Science into their business strategies, it has resulted in creating a number of jobs in the Data Science field.

Tools required for Data Science. #

Now that we have understood why we need Data Science, let us move on to understanding the tools involved in Data Science.

Data Science has various tools, some of which are discussed below:

R programming language:
- R is a programming language widely used by Data Scientists and many organizations for data analysis
- R language possesses the feature of Object Oriented Programming Language
- R programming language is also used for statistical analysis, graphics representations and reporting.
Python programming language:
- Python is an Object Oriented Programming Language widely used for Data Science and software development
- Python works on different platforms like Windows, Mac, Linux, etc.
- Python can also be used to develop several applications like web applications, Graphic User Interface based applications, Scientific and numeric applications, etc.
Structured Query Language (SQL):
- Structured Query Language (SQL) is used to create new databases, tables and views. It is used to insert and update records in a database
- Structured Query Language (SQL) is also used for deleting records from database and also to retrieve data from a database
- Data Scientist uses Structure Query Language (SQL) for managing and querying data stored in the database.
Hadoop:
- Hadoop is an open source framework used to store and process big data
- Hadoop provides Big data analytics through distributed computing framework
- Hadoop provides flexibilities as the users don’t need to preprocess the data before storing it. You can store as much data as you want and decide later on how much of it you want to use.
