With a changing landscape in the workforce, many people are either changing their careers or applying to different companies after being laid off. Some of those people are data analysts who want to become data scientists, or some of them are data scientists who are changing companies and will need to focus some of their time on learning or refreshing their data analytics knowledge.

You could assume that data analysis is already taught in data science programs, but in my experience, I have seen an immediate jump to data science, or more specifically, machine learning algorithms. Just like how it is easy to assume now that a data scientist would already know data analytics, so do some universities or online courses that jump right into the meat of common machine learning concepts. This assumption can lead to some data scientists struggling in data analytics. Although it seems that it might be more simple at first, data analytics is the foundation of data science. You must understand your business, your data, and your metrics. This information is ultimately what feeds your statistical methods and data science models.

Below, I will summarize data analytics and data science, and give some examples of why data analytics is so important to data science.

Data Analysis

Data analytics is oftentimes referred to as business intelligence, BI development, or product analytics. This field is found at nearly every tech business, and most other businesses as well. It is essential to practice data analytics at a company to ensure visibility of company finances, customer data, and areas for improvement where a future machine learning model could be applied. Data analytics can be found using tools like:

Tableau, Looker, Google Data Studio, SQL, Excel, and sometimes Python.

Examples of data analytics can be:

  • finding the top users of a product
  • gathering key demographics of those users
  • summary metrics for a product
  • finding seasonal trends in user behavior
  • highlighting anomalies in financials

As you can see from the above examples, all can be applied to the data science process in some way. These examples can also serve as features or attributes that will be inputted into your model.

Data Science

Data science is becoming more and more popular as a career path for many people to take. It is essentially a career where you automate otherwise manuals processes with the use of programming languages and statistics. Its foundation is based on data analytics and mathematics. Common tools that data scientists can expect to use are:

Data Analysis, SQL, Tableau, Python, R, SAS, Terminal, Jupyter Notebook, AWS, GCP, sklearn and TensorFlow libraries (as well as many more).

There are several parts of the overall process in data science that can include data analysis, such as data formation/creation, data cleansing, exploratory data analysis (especially this part), feature engineering, and interpretation of suggestions/predictions/results.

Examples of data science can be:

  • clustering for customer behavior
  • categorization of clothing styles
  • face image detection and categorization
  • a chatbot utilizing natural language processing (NLP)
  • automatic anomaly detection for fraud

Most, if not all, of these examples, are based on data analysis firsthand, as well as after the data science process.

How Are Data analysis and Data science Different From Each Other

With possibly everything that one can think of which revolves around data, the need for people who can transform data into a manner that helps in making the best of the available data is at its peak. This brings our attention to two major aspects of data – data science and data analysis. Many tend to get confused between the two and often misuse one in place of the other. In reality, they are different from each other in a couple of aspects. Read on to find how data analysis and data science are different from each other.

Before jumping straight into the differences between the two, it is critical to understand the commonalities between data analysis and data science. First things first – both these areas revolve primarily around data. Next, the prime objective of both of them remains the same – to meet the business objective and aid in the decision-making ability. Also, both these fields demand the person be well acquainted with the business problems, market size, opportunities, risks and a rough idea of what could be the possible solutions.

Now, addressing the main topic of interest – how are data analysis and data science different from each other.

As far as data science is concerned, it is nothing but drawing actionable insights from raw data. Data science has most of the work done in these three areas –

  • Building/collecting data
  • Cleaning/filtering data
  • Organizing data

How To Build A Data Science Career In 2021

For this week’s data science career interview, we got in touch with Dr Suman Sanyal, Associate Professor of Computer Science and Engineering at NIIT University. In this interview, Dr Sanyal shares his insights on how universities can contribute to this highly promising sector and what aspirants can do to build a successful data science career.

With industry-linkage, technology and research-driven seamless education, NIIT University has been recognised for addressing the growing demand for data science experts worldwide with its industry-ready courses. The university has recently introduced B.Tech in Data Science course, which aims to deploy data sets models to solve real-world problems. The programme provides industry-academic synergy for the students to establish careers in data science, artificial intelligence and machine learning.

“Students with skills that are aligned to new-age technology will be of huge value. The industry today wants young, ambitious students who have the know-how on how to get things done,” Sanyal said.

Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.

'Commoditization Is The Biggest Problem In Data Science Education'

The buzz around data science has sent many youngsters and professionals on an upskill/reskilling spree. Prof. Raghunathan Rengasamy, the acting head of Robert Bosch Centre for Data Science and AI, IIT Madras, believes data science knowledge will soon become a necessity.

IIT Madras has been one of India’s prestigious universities offering numerous courses in data science, machine learning, and artificial intelligence in partnership with many edtech startups. For this week’s data science career interview, Analytics India Magazine spoke to Prof. Rengasamy to understand his views on the data science education market.

With more than 15 years of experience, Prof. Rengasamy is currently heading RBCDSAI-IIT Madras and teaching at the department of chemical engineering. He has co-authored a series of review articles on condition monitoring and fault detection and diagnosis. He has also been the recipient of the Young Engineer Award for the year 2000 by the Indian National Academy of Engineering (INAE) for outstanding engineers under the age of 32.

Of late, Rengaswamy has been working on engineering applications of artificial intelligence and computational microfluidics. His research work has also led to the formation of a startup, SysEng LLC, in the US, funded through an NSF STTR grant.
