With the boom of Information Technology, a life Changing Revolution in Human History, people started using Word Wide Web and Web 2.0. That technology created a large amount of data. But, from the late 19th century, more and more people started using Global Network System – the Internet. In these decades web 2.0 changed the lifestyles of the majority of people outside the selective elite.

With the revolution of Mobile Technology, people started using the internet as their daily life need. Almost on average more than 45% of the time people use the internet or interact with the digital world. This is because of social connectedness in the form of social media. People started creating huge amounts of data as at every step of the digital world data is generated. To properly use this Data for Business benefits and growth, the transformation of Data into Information become necessarily important, and this job is done by Data Analysts.

The role of the Data Analyst is to pick useful insights from raw Data and make visual representations of these insights. Hence, Data Analytics is important for businesses to utilize Big Data for their corporate and business benefits.

Further, Online businesses use this data to acquire their customers through either Social Media Marketing or Advertising. In other cases, such as on Netflix, past interactions are used to guess the choice for web series etc. Amazon uses a machine learning model to suggest products to increase converts. All these tasks are done by using Machine Learning Models and Modelling. This job is done by the Data Scientists.

The role of a Data Scientist is to make machine learning models, to help business to increase their reach and obviously grow their businesses. Therefore, Data Science is essential for handling raw data and utilizing this big data for business and other predictions.



What is Data Analytics and who is Data Analyst?

Data Analytics:

Data Analytics is the subject of Computer Systems which uses knowledge of programming and visual frameworks or software to convert different data points of business surveys or weather reports etc into visual insights for businesses to take measured decisions. It is a sub-subject of Data Science, as Data Analytics is part of the Data Science Cycle. Modern Day Businesses use big data to categorize their customers, and mould business strategies as per insights of big data.

Hence, the demand for Data Analytics is increasing day by day in business industries. Stock brokering companies uses data insights, generated by data analytics, to guess market trends. Managers of Hotels at Touristic Place of Sindh, see the insights of customers coming to the Hotel month by month. He can provide discounts on the months when fewer number visitors come to the hotel.


Data Analyst:

Data Analyst is a technical person, who is responsible for picking out useful data insights from the given raw and unorganized data in form reports etc. All small-size companies like stock brokering agencies and startups hire Data analysts for summarizing their business directions. The demand for these technical jobs is increasing day by day as every next company measures their market and evolves itself accordingly.

Hence, the role of a Data Analyst is an important part of modern-day companies. They are highly paid for their unique skills i.e., Python Programming, Mathematical Statistics and Data Visualizing Software.

Data Science is an umbrella of multiple technological subjects like Data Analytics, Machine Learning, and other big data-related subjects. Data Science utilizes the Advanced Mathematical Statistics, High-Level Programming Language Skills, needed for Big Data i.e., Python or ‘R’ and Machine Learning Algorithms to design Automated ML Models.

Linear Regression Line is drawn on available past values. This Line is used for future guessing.

For Example, A Real State Website uses this kind of Machine Learning model to guess the price of the property based on certain conditions.


Data Scientist:

Data Scientist is an individual who is responsible for doing all the tasks of Data Science to enhance the experience of users and helps businesses to grow rapidly. They are highly skilled people. They must have strong knowledge of Statistics, Python or ‘R’ Programming Language and Modelling.

Hence, the role of a Data Scientist is very important in modern-day companies, especially in the digital world. Instagram, Facebook and Youtube etc, use Data Science to train models for showing posts or videos based on past user preferences.
