What is Big Data Science?

Big Data and Data Science are often mentioned together. Alternatively, it is even referred to Big Data Science directly. Here, we briefly describe where the approaches profit most form another.

Why Big Data and Data Science often converge to Big Data Science?

Data Science uses scientific methods, processes, algorithms and systems to extract insights and knowledge from data to generate enterprise value. Thereby the data volume varies, depending on the specific investigation task.

Big Data is about processing data in large volume, variety, velocity and with unknown veracity.

Thus, Data Science can also be executed on top of Big Data. We can also refer to this as Big Data Science.

Logically, the goal of an enterprise is to become data driven with the aspiration to normally to use larger amounts of data.

In addition to its pure volume, an enterprise has plenty of different IT Systems. These data are needed so it can be merged within data driven projects and Big Data Science analysis shall be done.

Therefore, a Data Lake is often used as foundation for a Data Science workbench.

Data Scientists uses a workbench like Jupyter or Zeppelin to access the Data Lake with different languages such as R, Phyton, Scala and others.

We see this in the following picture visualized. There a Big Data infrastucture integrates different data sources and provides access to the data. Data Scientists use the provided data models, a data catalog and do Big Data Science investigations.

Architecture how message queues, databases, documents and open data get processed into a data lake. Subsequently this data gets meshed and indexed into cataloges and masterdata is identified. Data scientists then investigate the data by their data models.
Big Data information is extracted, structured, cleaned and stored into models, enlisted in a repository and flagged as master or transactional data for analysis. Data Scientists use these information to examine and investigate thoroughly to make their catch worthwhile.

Synergies of Big Data Science

In addition to other reasons to combine Big Data and Data Science, there are also synergies.

Big Data preparation, processing and infrasctuture

Most of the time in data investigations are spent to prepare the data.

Data wrangling costs Data Scientists 80% of their time. This means integrating data, filtering, cleaning data or combining data out of different sources need tools for support.

Big Data infrastructures offer the possibilities to store, combine, process and filter data in large amounts; this makes it handy or even necessary to have a Big Data storage and processing and computation infrastructure available.

Big Data volume and scaling

Alternatively, machine learning applications need Big Data foundations and different algorithms like Deep Learning with neuronal networks or other methods require a vast amount of data to work and to be tested.

Alternatively, the issue Big Data have often are missing records or facing other quality issues. One possibility to clean data is to use Data Science methods such as machine learning.

A good example to show this would be machine learning, which can label unstructured data Variety and match it this way to structured data. Similarly, Data Science methods can help to overcome Veracity challenges and determine which records of which system are the truthful one.

Last but not the least, such automated approaches can cope with the large amout of data and execute these actions with high performance to overcome Volume and Velocity of Big Data.


Big Data and Data Science are complementary to each other or even needed together to achieve better dynamics for the analytics in Big Data Analytics results, or to supply Data Science with a larger data amount.

Therefore, one can call the combination of Big Data and Data Science simply Big Data Science
