What makes data a precious commodity?
The answer to these questions lies in the way companies have sought to transform their products.

Data Science is a very recent terminology. Before Data Science, we had statisticians. These statisticians experienced in qualitative analysis of data and companies employed them to analyze their overall performance and sales. With the advent of a computing process, cloud storage, and analytical tools, the field of computer science merged with statistics. This gave birth to Data Science.

Early data analytics based on surveying and finding solutions to public problems. For example, a survey regarding a number of children in a district would lead to a decision of development of the school in that area. With the help of computers, the decision-making process has been simplified. As a result, computers could solve more complex statistical problems. As Data started to proliferate, companies started to realize its value. Its importance reflected in the many products designed to boost customer experiences. Industries sought experts who could tap the potential that data holstered. Data could help them make the right business decisions and maximize their profits. Moreover, it gave the company an opportunity to examine and act according to customer behavior based on their purchasing patterns. Data helped companies boost their revenue model and helped them craft a better quality product for clients.

Data is to products what electricity is to household gadgets. We need data to engineer the products that cater to the users. It is what drives the product and makes it usable. A Data Scientist is like a sculptor. He chisels the data to create something meaningful out of it. While it can be a tedious task, a Data Scientist needs to have the right expertise to deliver the results.
