Big Data Vs Predictive Analytics

Difference Between Big Data and Predictive Analytics

As one of the most “hyped” terms in the market today, there is no consensus on defining Big Data and Predictive Analytics.

 

 

Big data is high-volume, high-velocity, and/or high-variety information assets that demand cost-effective, innovative forms of information processing that enable enhanced insight, decision-making, and process automation. Big Data has emerged as an important area of interest in study and research among practitioners and academicians. The exponential growth of the internet and digital devices fuels the exponential growth of data. Technology advancements are making it economically feasible to store and analyze huge amounts of data. Big Data includes a mix of structured, semi-structured, and unstructured real-time data originating from various sources.

Predictive analytics encompasses a variety of statistical techniques from modeling, machine learning, and data mining that analyze current and historical facts to make predictions about future or otherwise unknown events. Predictive Analytics provides a methodology for tapping intelligence from large data sets. Many visionary companies, such as Google, Amazon, etc. have realized the potential of Big Data and Analytics in gaining competitive advantage. These techniques provide several opportunities, like discovering patterns or better optimization algorithms. Managing and analyzing Big Data also constitutes a few challenges – namely, size, quality, reliability, and completeness of data.

Key Differences Between Big Data and Predictive Analytics

Below is the list of points that describes the key difference between Big Data and Predictive Analytics :

  1. Architecture

Big Data has to do with the quantity of data, typically in the range of .5 terabytes or more, where the capacity of relational database systems starts to degrade. Hence, the need for cloud-based pipelines like AWS and data warehouses is the need of the hour. On the other hand, Predictive analytics has to do with applying statistical models to existing data to forecast likely outcomes with the churned data sources.

  1. Target Problem

“Big Data” describes the data itself and the challenge of managing it, while “Predictive Analytics” describes a class of applications for the data, regardless of quantity. So, both of them represent mutually exclusive entities.

  1. Social Media Use Cases

Social Media has proven to be the best use for both Big Data and Predictive Analytics. But both of them serve as a sequential chain to each other. As Social Media data comes from multiple sources but eventually gets into an MDM(Master data Management) which can be built via Big Data technologies only on which the Predictive Analytics and other algorithms can be fired to give the outcomes. This new type of data management solution bears the trademark of being highly scalable, massively parallel, and cost-effective.

  1. Technology Ecosystem in Big Data and Predictive Analytics 

The sweet spot for Big Data Platforms and Predictive Analytics, for instance, is dealing with high-value transactional data that is already structured, that needs to support a large amount of users and applications that ask repeated questions of known data (where a fixed schema and optimization pays off) with enterprise-level security and performance guarantee. So to deal with them, we have different tools and technologies.

For Big Data,

AWS, Apache HDFS, Map Reduce/Spark, Cassandra/HBase.

For Predictive Analytics,

R, Statistical methods, forecasting, regression analysis, Data Mining, Data Warehouses.

Big Data and Predictive Analytics Comparison Table

Following is the comparison table between Big Data and Predictive Analytics.

Basis of Comparison Big Data Predictive Analytics
The Basics Big Data has to deal with the cleansing and interpreting vast amounts of information, and it can be used in a broad area of business activities.  Predictive analytics is a method of forecasting business events and market behavior.

 

 
Level of Advancement It’s high. Big Data engines have eventually upgraded themselves throughout the development processes and level of cross-platform compatibility. Medium. Predictive Analytics, on the other hand, has a limited chance of algorithmic patterns as they are giving them better scores from the start with respect to their field and domain-specific work analysis.
Incorporates ML(Machine Learning) and AI(Artificial Intelligence) Big Data engines like Spark and Hadoop come with built-in Machine Learning libraries, but the incorporation with AI is still an R&D task for the Data Engineers. Predictive Analytics, on the other hand, deals with the platform based on probability and mathematical calculation. So it’s kind of feasible to embed ML and AI together with these platforms.
The UI and Dashboards Visualizations Big Data comes with vast backend technology imports for Dashboards and Visualizations like D3js and some paid ones like Spotfire, a TIBCO tool for reporting. On the other hand, Predictive Analytics tools come with built-in integrations of the reporting tools like Microsoft BI tools. So, no need to fetch it from a source or some outside vendors.

 
Data Size and Performance Enormous. It’s not a best practice to use Big Data platforms for lesser data amounts as the performance of Big data platforms is exponential in nature.

 

 Medium. Very large and Very less data sets can contribute to bad predictions and discoveries with respect to models and algorithms.
Popularity and Who uses them? Currently, very hyped. Everyone in the market wants to enter the Big Data domain. All the coding and implementations are handled by the Big Data Engineers and developers only. No, data Scientists are required for such kinds of processes. Popular only but not as Big Data. It depends on the use cases and the type of organization implementing it. For example, It’s very popular with healthcare and fraud detection organizations because of the use case compatibility. On the other hand, Predictive analysis is taken care of by Data Scientists and BA (Business Analyst) people and developers.

Conclusion

Big data vs Predictive Analysis, both are here and here to stay. Despite the hype, Big Data vs Predictive Analytics offers organizations tangible business benefits. It enables enhanced insight, decision-making, and process automation. There is also a so-called paradigm shift in terms of analytic focus. That is a shift from descriptive analytics to predictive analytics. The combination of Big Data and Predictive Analytics in all domains has the great potential to positively affect decision support and operations such as cost management systems and resource allocation.
