Statistics and advanced analytics techniques knowledge are crucial for implementing successful data analytics projects. The Data Science course covers these topics in a comprehensive manner with applications of R programming. Typically an analytics project consists of various phases such as manipulation, preparation, exploration, and visualization of different kinds of business data. Along with training modules on these phases, predictive analytics techniques like regression models, clustering, and decision trees are covered using real-time case studies. Additional training modules around time series techniques and text analytics are also covered which helps in processing specific kinds of data such as text and social media content.

In the Big Data course, the emphasis will be more on handling and analyzing huge volumes of data to generate insights through summarization and visualization techniques. Instead of advanced analytics techniques, this course puts more emphasis on BI aspects such as exploratory analysis, building dashboards, and visualizations. Since Big Data technologies like Hadoop is a complex system compared to traditional SQL based systems, most of the learning modules will focus on data handling and processing using various components of Hadoop ecosystem such as MapReduce programming using Java, querying using HiveQL or scripting using Pig.


Since Big Data skills are a hot skill to have now and every business is actively looking out for the right talent, both the Big Data and Data Science courses consist of learning modules specific to working with Hadoop. The Data Science course provides an overview of Hadoop technology and writing MapReduce programs through R and Hadoop integration using RHadoop library. These libraries are designed and developed by Revolution Analytics majorly for R programmers who can interact with the Hadoop cluster through R syntax whenever such a need occurs. On the other hand, the Big Data course is all about Hadoop data processing and further how one can integrate tools such as R and Tableau with Hadoop for performing data analysis. More than half of the learning modules provide both technical and hands-on knowledge related to configuration and data processing using Hadoop and its various components such as HBase, Hive, Flume, and Sqoop.

Regards the case studies dealt with in the courses, both the Big Data and Data Science courses differ in terms of end applications, with the former focusing more on massive datasets and the latter focusing more on predictive analytics problems. In the Data Science course, the concepts of predictive analytics techniques using R software across industry verticals such as retail, finance, and telecom are used. Some of the examples of these business problems are a prediction of telecom churn, the sale price of cars, credit risk behavior, and marketing mix modeling. Even in the Big Data course, the emphasis would be more on analytics-related problems across various domains such as exploratory analyses and visualizations along with installation and configuration aspects of the Hadoop cluster. On the analytics side, text mining would be covered extensively as Hadoop technologies are more popular in dealing with unstructured data problems. Some of the problems that will be covered are social media analytics with Twitter data, web analytics on clickstream data, and financial analysis using stock data.

Which course suits your career aspirations better?

In terms of career fit, the Data Science course would be beneficial for those who want to learn extensive R programming to use it for executing analytics projects, whereas the Big Data course is for those who are looking at building Hadoop expertise and further using it in collaboration with R and Tableau for performing standard data analysis tasks and building dashboards. If you are looking to build stronger expertise around implementing statistical and predictive analytics techniques then the Data Science course would be the right choice whereas the Big Data course would benefit those looking to become competent in processing data using Hadoop and also work with R and Tableau to create BI reports and dashboards.

Generally, the Data Science course would best suit professionals working as data analysts, business intelligence engineers, business analysts, and IT application engineers who want to build advanced skills for making a successful career in the data analytics field. Even the Big Data course would be a good fit for these professionals if they are planning on building big data skills around working with Hadoop and move ahead in their existing career paths. Alternatively someone working as a database administrator, or IT software and application engineer, or data warehousing professional can do the Big Data course to learn about big data technologies and also understand the concepts around working with Hadoop using analytics software’s such as R and Tableau and to develop a comprehensive data product or data flow meeting the end-to-end business needs.
