What Technology Tools Can Help Data Scientists?
To say the field of Data Science is exploding is truly an understatement. It only takes one statistic to be convinced. Did you know that by 2025, an estimated 463 exabytes of data will be created each day which is the equivalent of 212,765,957 DVDs? Studying such volumes of data requires a range of data science tools.
The sources and categories of data include the internet, social media, communications, services, digital photos and the Internet of Things. The stats are staggering. Here’s one example: Venmo has 40 million users and processes $68,493 in transactions EVERY minute.
Raw data in and of itself isn’t meaningful. Organizations need data insights to achieve business goals that range from improving the customer experience, gaining a competitive edge, facilitating product innovation, making scientific discoveries, predicting or preventing equipment failures, and much more.
Data scientists interpret data and extract insights that get shared with stakeholders who use them for decision-making purposes. Before the most relevant insights can be extracted, data must be prepared, processed and analyzed.
To accomplish the discovery and delivery of key findings, data scientists need the right technology tools and services for each phase of the data science life cycle.
But First, What is Data Science?
Data science is the study and interpretation of data to discover insights that organizations use for making business decisions. Whether it’s a digital transformation initiative, research project or effort to improve the customer experience, studying and understanding data to discover what it’s revealing is essential to moving forward intelligently.
That’s where data scientists come in. They work across the data science life cycle that starts with data collection and cleaning, then continues with dashboard and report creation, data visualization and statistical interpretation. Finally, data scientists are responsible for communicating results to key stakeholders and convincing decision-makers about the validity of insights based on their knowledge of the business.
It’s important to note that one doesn’t have to be a data scientist to contribute to the discovery of data insights – particularly in large organizations. Data engineers may manage tasks associated with data preparation. Data analysts often play a key role in data visualization and communicating the data insights and their validity to key stakeholders.
Due to the significant skills gap in the field of data science, another role has emerged. It’s the Citizen Data Scientist.
Data science tech tools have evolved to the point that much of the data preparation can be automated as well as certain steps of the analysis. There have also been rapid developments in both the open-source ecosystem of tools as well as commercial, productized data science tools. All of these advancements in tools make it easier for citizen data scientists to play a key role in the various phases of the data science life cycle.
Data Science Technology Tools and Services
Tools used by data scientists may be all-inclusive or apply to specific phases of the Data Science Life Cycle. There are platforms, core programming languages, frameworks, and standalone technologies.
The list is inclusive of machine learning (ML) technologies since ML is one of two paths that data science follows, the other is based on statistical analysis. Finally, those tools that can be used without having programming skills will be noted.
There are several platforms data scientists can use to manage, analyze, visualize and model data. Several of these platforms also provide machine learning capabilities that can be used by data scientists or other stakeholders – with or without programming skills.

Programming for data science is unique in that it is data-centric and designed to help users process, analyze and generate predictions from their data as well as carry out algorithms specific to data science. Data scientists must master one or more data science programming languages to become proficient in their role.
Python is a high-level programming language with five key features: object-oriented, functional, procedural, dynamic type, and automatic memory management. It provides a large standard library as well as packages for natural language process and data learning.
Python is used by 83% of the nearly 24,000 data professionals who responded to a Machine Learning and Data Science Survey conducted by Kaggle in late 2018. Notably, 3 out of 4 of those same data pros believe that aspiring data scientists should learn Python first.
R is a programming language that is used with a UNIX platform, Windows, or Mac OS by statisticians and data miners for developing statistical software, performing data analysis and data visualization. This highly extensible language provides a wide variety of statistical and graphical techniques.
While open-source R is considered a more difficult language to learn, it is better-suited for ad hoc analysis and exploring datasets than Python.
Java is another programming language that is object-oriented and includes these key features: architecture-neutral, platform-independent, portable, multi-threaded, and secure. It is fast and scales easily for larger applications and has specific libraries and tools for machine learning and data science.
SQL is a domain-specific language data scientists use to manage data stored in a relational database management system (RDBMS). Data scientists must know how to work with data in database management systems which makes it essential that they understand SQL tables and know how to use SQL queries.
Hadoop and Spark are big data frameworks that include some of the most popular tools for performing basic tasks. While there is some crossover between the two, the frameworks also perform different tasks.
Hadoop uses a distributed approach to store substantial amounts of data and process the data in parallel across clusters of commodity hardware which is far more efficient than running data on a single device.
The newer and more advanced Spark is a fast, flexible framework data scientists use for large-scale SQL, batch processing, stream processing, and machine learning. While Spark does have the advantage of working much faster than Hadoop, it does not have a distributed data storage system.
There are use cases for using one of the frameworks or both. For example, Hadoop will be sufficient if a big data project is focused on analyzing a structured dataset. The project does not require the advanced streaming analytics and machine learning functionality provided by Spark.
Here’s another example. Since Spark does not have its own system for distributed data storage, Spark will need to be installed to run over Hadoop for specific types of big data projects. This allows the Spark analytics applications to access data stored using the Hadoop Distributed File System (HDFS).
Spark has emerged to be the front-runner of the two frameworks as it is considered to be a more advanced product than Hadoop. Designed to work by processing data in chunks “in memory” instead of using physical, magnetic hard discs, data processing can be completed more quickly – up to 100 times faster in certain circumstances.
