Who is Data Scientist?

Data science is a complicated and sometimes perplexing discipline that requires hundreds of different abilities, making it difficult to define the field. A data scientist is simply somebody who collects and analyzes information to conclude. They use a variety of methods to do this. They might well graphically view the data, a process known as “visualizing the data,” that allows a user to search for simple trends that would have been missed if the details were represented in actual figures through a spreadsheet. They also develop highly sophisticated algorithms designed to identify trends and transform data from either a jumble of facts and figures into something valuable to a company or organization. At its most basic level, data science is the process of searching for significance in large quantities of data.

Skills and Qualities of Data Scientist

Technical Skills: Computer Science

  • Python Coding

Python can be used for practically every phase in the data science procedure. It accepts a variety of data types and allows you to import SQL databases into your program effortlessly. It enables you to construct datasets, as well as Google can practically provide you with whatever dataset you require.

  • Hadoop Platform

As a data scientist, you might find yourself in a position where the amount of data you have surpasses the RAM available on your device, or you require to send information to other servers; that’s where Hadoop enters in. Hadoop can be used to send data to different parts of a system swiftly. That’s not all, though. Hadoop is used for information collection, filtration, sample, & summarization.

  • SQL Database/Coding

As a data scientist, you must be fluent in SQL. This is because SQL was created to assist you in accessing, communicating, and working with data. When you use it to query a database, it provides you with information. It has short commands which can save users time & decrease the number of programming required to run complex searches. Learning SQL will improve your understanding of relational database systems & support you in advancing your career as a data scientist.

  • Apache Spark

Apache Spark is quickly becoming the best widely used big data tool on the planet. It’s a Hadoop-like large data computing framework. The sole difference between Spark and Hadoop would be that Spark is quicker. This is because Hadoop reads & writes to storage, slowing it down, whereas Spark caches all calculations in mind.

Apache Spark was created primarily for data science to speed up the execution of complex algorithms. When dealing with a large amount of data, it aids in spreading data processing and so saves time. It also assists data scientists in dealing with large, unstructured data volumes. It can be used on a single machine and a group of machines.

Non-Technical Skills

  • Intellectual Curiosity

Since data scientists invest around 80percent of their time finding & preparing the information, you must be capable of asking queries about it. This is because the subject of data science is rapidly evolving, & you will need to study more to catch the pace. You should keep your expertise updated by studying internet articles and books about data science developments. Don’t be intimidated by the vast amount of material circulating on the internet; you must be able to decipher it all.  

  • Business Acumen

To become a data scientist, you must have a thorough awareness of the industry in which you operate and be aware of the business issues that your organization is attempting to solve. Regarding data science, the ability to detect the problems remains vital to resolve for the organization. Identifying innovative methods the firm might leverage its data is vital. To do just that, you must first comprehend how the issue you are solving may affect the organization. That’s why you must understand how business works to focus your work appropriately.

  • Communication Skills

Companies asking for a competent data scientist want somebody who can effectively and fluently communicate their technical results to non-technical staff, like Marketing and Sales. To manage the data effectively, a data scientist should allow the company to make decisions by providing them with quantitative insights and knowing the demands of their non-technical coworkers. For more about communication qualities for quantitative experts, take a look at our latest flash poll.

  • Teamwork

A data scientist can’t do his or her job by themselves. You’ll have to collaborate with business executives to establish plans, product managers & creators to enhance goods marketers to execute more effective campaigns, and client-server software engineers to build data pipelines & optimize workflow. You’ll have to collaborate with everybody in the company, including your clients. Essentially, you’ll work with your teammates to create user scenarios so that you can understand the business aims & data needed to address challenges.

Salary of a Data Scientist
