What is Data Science?

Data science is a broad field that refers to the collective processes, theories, concepts, tools and technologies that enable the review, analysis, and extraction of valuable knowledge and information from raw data. It is geared towards helping individuals and organizations make better decisions from stored, consumed and managed data.

Data Science blends various tools.  It makes use of algorithms and machine learning principles with the goal to discover hidden patterns from the raw data.

Who is a Data Scientist?

A data scientist basically works with raw data using various tools and algorithms to solve critical data analytic problems.

While other experts take care of building software (which is used to collect data from multiple sources), coding models, and application of data collection tools and methods respectively, a data scientist takes care of collecting and storing data pulled in from several sources, analyzing and visualizing the data, and finally deriving insights from it. 

A data scientist spends a lot of time in the processing, cleaning, and munging data. This process requires persistence, statistics, and software engineering skills.

 

Why We Need Data Science?

Generally, experts generate data from different sources like financial logs, text files, multimedia forms, sensors, and instruments. Simple business intelligence tools are not capable of handling this large volume and variety of data that is why we need data science to help in the processing and analysis of these complex tools. Besides processing huge variety of data, there are still other functions and importance of data science in various domains.  Below are some of the importance of data science.

Precision: The data gathered over time can be used for predictions that will help in decisions making and will help provide better results. Now let’s take business as an example, imagine you can train models more effectively and recommend products to your customers with more precision. How direct and easy it has made business, because you will be able to understand the precise requirement of your customers.

Decision Making: When you have a large variety of data, it can be used for decision making. Let us take a look at a basic scenario, imagine your car has the intelligence to drive you to work, won’t it be amazing? This is how it will work; the self-driving car collect data from sensors, radars, camera, and lasers to create a map of its surroundings. Based on this data, it makes decisions like when to slow down, when to speed up, when to overtake, where to turn to etc. making use of advanced machine learning algorithms.

Predictive analysis: Data science can be used in the predictive analysis that will help predict events or occurrences to come. Looking at the importance of data science in predictive analysis like weather forecast, it is easy for us to appreciate the efforts of data scientist. Data from ships, aircraft, radars, satellites can be collected and analyzed to build models to forecast the weather and predict the occurrence of any natural disaster.

Careers in Data Science

Just like every other career, data science is one career that provides room for growth and development. Many persons think that starting a career in data science is all about being a data scientist, but there are other specializations. So if you are thinking of starting a career in data science, it is also important for you to get familiar with other areas in the field.

Below are the different careers in data science;

Data Analyst

Data Analysis is the art of collecting and analyzing data so that a company or companies can use the said data to perfect their marketing, insurance, political and business practices.

The data analyst is a highly trained professional who sorts and organizes and runs various mathematical calculations to determine how the data samples might best be applied to profit the business.

The typical duty of a data analyst is to; produce a report, spot patterns, collate data and set up infrastructures.

Machine Learning Engineer

Like we said earlier, the main aim of a data scientist is to use different tools and algorithms to solve problems. Problem solving and artificial intelligence is the goal of a machine learning engineer.

Machine learning engineers are computer programmers, but their focus is beyond programming machines to perform specific tasks. They rather create programs that will enable the machine to perform a task without being specifically directed to perform those tasks. A good example of a system that a machine learning engineer would work on is a self-driving car.

Machine learning engineers work on different applications that range from programming services to identifying specific needs and interests. They also customize news feeds and tailored web searches. Machine learning engineers contribute immensely to the daily lives of individuals and how they use technology.

The Data Engineer

Data engineering is another specialized career in data science. Data engineers are the designers, builders, and managers of “big data” infrastructure. They develop the framework or architecture that helps to analyze and process data. A data engineer is an engineer that specializes in building data pipelines to pull information from different source systems. A data engineer integrates, consolidates, cleanse and structure data for individual analytics applications.

A good data engineer should have a good experience in software engineering. Big data engineers should also have the capability to architect highly scalable distributed systems, using different open source tools.

Data Science Generalist

A data science generalist focuses on using big data and algorithms to solve problems. The main job of a data science generalist is to experiment with the latest algorithms and statistics to find the best way to solve a data science problem.

Some of the most important data generalist skills are; familiarity with tools designed for ‘big data,’ and an experience in real-life datasets.
