Data Science - sometimes referred to as Data Mining or Big Data Analytics - is the advanced analysis of data in order to extract critical insights that allow us to understand the past and to more accurately predict the future. It is a multidisciplinary approach that integrates standards and practices from the fields of mathematics, statistics, measurements, man-made reasoning, software design.

At its core, data science is about learning behaviors, processes and performance through the analysis of data. This involves understanding the structure of the data, deriving patterns and insights from it, and finally communicating these findings to others so that fact-based decisions can be made. Data Science is a tool for businesses to make better decisions. It can help you understand your customers better, optimize and prioritize your efforts, predict future trends and much more.

Why Data Science is important?

There is typically no shortage of data in any organization. The value of Data Science is the ability to analyze multiple sources and types of data (which may not have much value individually) in order to create a more profound understanding of what is actually happening. Data Science provides us with great insight to understand behaviors (of employees, customers, the marketplace), processes (understanding patterns and trends, causes and effects) and performance. With a deeper understanding of reality, we are much better poised to make decisions, to predict future behaviors and performance, to focus and prioritize much more efficiently and effectively.

Uses of Data Science Across Industries

Data Science has proven extremely valuable across industries. Below are just a few examoles of Data Science in some of the industries that have benefited the most from Data Science: 

1. Retail

The main objective - and greatest challenge - for retailers is to accurately predict what their customers will want to purchase, and then to provide those items. If the retailers cannot accomplish this, someone else will. Data Science provides retailers with the information they need in order to have an advantage over their competitors. Retailers use Data Science to create targeted personal shopping experiences that keep customers very engaged and satisfied, which means they are much more likely to make the decision to purchase.

2. Healthcare

The healthcare industry has experienced a multitude of benefits from Data Science, including better models for predicting disease or outbreaks, getting life-saving drugs to market more rapidly, early detection of diseases, identification of risk factors for chronic conditions, and improved patient care (based on individual patient data). Patients are now able to use wearable trackers that provide important real-time information to physicians. Data Science provides medical professionals much more actionable data that allows them to focus more on the patient's well-being, to prescribe more appropriate treatment plans, and it allows facilities to improve care and reduce waiting times.

3. Banking and Finance

As one of the most data-driven and transactional industries, banking and finance have vast opportunities for better understanding of their data. Banks are now using natural language processing and predictive analytics to create virtual assistants to help customers with inquiries and basic transactions. Using Data Science, these virtual assistants "learn" more with each transaction by analyzing patterns and behaviors.

4. Construction

This might be a surprising industry for Data Science, but construction is one of the biggest growth areas, and here's why. Construction companies track (or should be tracking) absolutely everything; from the thousands of tasks that need to be done, to the timeline, the dependencies, the materials, labor and everything in between. Data Science is being used to reduce the amount of unnecessary or unforeseen expenses and wasted time and delays. Overall, Data Science allows for much better decision-making by keeping projects on track.

5. Transportation

Getting to the right destination at the right time is always important. Data Science is used in the public and private Transportation industries to increase the performance of on time and accurate journeys. Statistical data is used to understand customer routes, unexpected situations and to provide travelers with personalized travel details. Predictive analytics are used to prevent issues and to detect causes of delay as early as possible. Substantial data gathered from travelers worldwide allows Data Scientists to analyze the data to prevent, detect and mitigate any travel obstacles. 

6. Entertainment and Media

As consumers, we all expect rich media in diverse formats on various devices. Data Scientists are collecting, analyzing and utilizing these insights. Social media and mobile content is now being leveraged to understand real-time patterns. With Data Science techniques, organizations can create higher quality content for a variety of target audiences, they can measure the performance of the content and then recommend on-demand content. An example of this is on-demand music streaming that analyzes data from millions of users to provide a better experience for each individual user.

Benefits of Data Science

There are many benefits of data science. It can help you make better decisions, understand your customers better, and improve your business operations. Additionally, data science can help you save time and money by automating tasks that would otherwise be done manually. Finally, data science can also help you improve your decision-making processes by providing insights that you may not have otherwise considered. In this day and age, information is being created at a mind-boggling rate. Consistently, loads of information is created; be it from the clients of Facebook or some other person-to-person communication site, from the calls that one makes, or the information that is being produced from various associations.

Data Science helps associations know how and when their items sell best, and that is the reason the items are conveyed consistently to the ideal locations and perfect opportunities. Quicker and better choices are taken by the association to further develop effectiveness and procure higher benefits. By analyzing customer data, businesses can develop more targeted marketing campaigns. Additionally, data science can help businesses improve their operations by identifying inefficiencies and areas for improvement. Furthermore, data science can be used to develop new products and services. Businesses can identify trends and patterns that can be used to create new offerings that meet customer demand. Finally, data science can help businesses reduce risk. They can find or predict potential risks and take steps to avoid them. Ultimately, Data Science can help businesses improve their bottom line by increasing revenues and reducing costs. Data Science for You?

Data Science is an exciting field in which each of us is participating on a daily basis. And it is growing rapidly in popularity for good reason. Data Science can be used to tackle problems that are too complex or difficult for traditional methods, and it can be used to find hidden patterns and relationships in data.

Data Science Process and Tools

Data science is a process that uses data to solve problems. The first step in Data Science is to gather required data. This data can come from anywhere, but it must be accurate and reliable. Once the data is collected, it must be cleaned and organized so that it can be analyzed. Next, the data is analyzed to find patterns and trends. Finally, the findings are reported so that they can be used to make decisions.

Data Science uses scientific methods, processes, algorithms and systems to extract knowledge and insights from data in various forms, both structured and unstructured. There are many different tools that data scientists use to perform their tasks effectively. Some of the best popular ones include:
