There are numerous tools associated with data science. If you are someone who is new to the field, you will be overwhelmed and intimidated by the number of data science tools. This article is for those who are looking to move to a data science field or have just started and want to know which tools can help them start their career as a data scientist.

Data science has become one of the most attractive tech profiles in the present day. You will find various news reports and articles stating how data science is the career that you should go for. However, most articles won’t give you an idea of how you can start your career and just throw some random tool names at you.

To learn more about data science, read our blog on – What is data science?

When you are just starting out to become a data scientist, this question will surely haunt you, “which tools should I learn first?” You will be inundated with various suggestions to learn a long list of tools. But when it comes to most data scientists, they all have a similar learning pattern. If you learn more than four to five of the common tools that we are going to mention here, you should have a good career start, earning a salary near to the industry median. You will also get a good idea of how to start your learning if you are wondering to take up professional data science courses.

Before starting with the tools, I hope you have a good concept of basic statistics and mathematics. Otherwise, just the knowledge of tools won’t be enough.

You don’t require any programming or coding skills to work with these tools. These data science tools offer a constructive way to define the entire Data Science workflow and implement it without any coding bugs or errors. 

This article is divided into two segments –

Segment 1 – Basic Data Science and Machine Learning Tools

Segment 2 – Advanced Data Science and Machine Learning Tools

 

Segment 1 – Basic Data Science and Machine Learning Tools

Let us look at the various types of basic yet important tools used in data science. We will use the tool ecosystem as described in a report by O’Reilly, which will help us to understand the data science environment better.

Cluster 1 (Microsoft-Excel-SQL)

Corresponding preferred role: Business Intelligence

  • Excel – The basic database and data analysis tool that most data scientists started out with. As you move to a higher role in data science, this tool won’t find any significance but it will still remain core to your work profile.
  • VBA – It is essential for those who work with Excel most of the time. With VBA, you can move one step into the field of automation. You can create your own complex functions that otherwise cannot be done simply through Excel’s library functions.
  • MS SQL Server/SQL – As your data grows, it might be difficult to store in Excel files as it can become slow and difficult to manage. MS SQL Server is an RDBMS (regional database management system) that offers good functionality in storing and retrieving data. SQL is the language that is used to manage data in an RDBMS.
  • SAS/SPSS – SAS and SPSS are both analytical software suites with proprietary licenses. SAS has been developed by SAS Institute while SPSS has been developed by IBM. Due to the popularity of R and Python, SAS and SPSS usage have gone down. However, it is still used by many industries as they are easy to learn and implement.

Cluster 1 is popular among those who have just started their career in data science as it gives them a good learning curve. Excel, SAS, SQL, and VBA are all easy to learn and does not require extensive programming skills.

 

Cluster 2 and Cluster 3 (Hadoop-Python-R)f

The corresponding preferred role for:

Cluster 2 – Hadoop and Data Engineering

Cluster 3 – Machine Learning and Data Analytics

  • Python/R – Both Python and R has been gaining popularity over the years as the go-to programming language for data scientists. R is hugely popular for its complex problem-solving capabilities. Python, on the other hand, is easier to learn if you have basic knowledge of object-oriented programming languages.
  • Hadoop – With the growing importance of big data in analytics, Hadoop is an important tool for process huge datasets.
  • Cassandra/MongoDB/NoSQL – RDBMS supports structured and predictable data. This becomes a disadvantage while working with big data. Cassandra, MongoDB, and NoSQL are useful for storing and managing unstructured data.
  • NumPy/SciPy – They are libraries for Python which can be used for high-level mathematical, scientific, and technical computing. It is one of the widely-used tools in Python programming.

 

Cluster 4 (Mac OS-JavaScript-MySQL)

Corresponding preferred role: Data Visualisation

This is a relatively new cluster and is more or less centered on the Mac OS.

  • JavaScript – In terms of data science, JavaScript is the least popular programming language but is highly useful for data visualization. It lacks the number of libraries in comparison to R and Python.
  • MySQL – It is important for server-side queries and helpful in extracting datasets from a relational database.
  • js – If you want to improve your data visualization through JavaScript, you can use the D3.js library. It offers stunning and powerful data visualization in web browsers.

 

Segment 2 – Advanced Data Science and Machine Learning Tools

 

RapidMiner

RapidMiner is a data science tool that offers an integrated environment for various technological processes. This includes machine learning, deep learning, data preparation, predictive analytics, and data mining. 

It allows you to clean up your data and then run it through a wide range of statistical algorithms. Suppose you want to use machine learning instead of traditional data science. In that case, the Auto Model will choose from several classification algorithms and search through various parameters until it finds the best fit. The goal of the tool is to produce hundreds of models and then identify the best one.

Once the models are created, the tool can implement them while testing their success rate and explaining how it makes its decisions. Sensitivity to different data fields can be tested and adjusted with the visual workflow editor.

Recent enhancements in RapidMiner include better text analytics, a greater variety of charts for building visual dashboards, and sophisticated algorithms to analyze time-series data.

RapidMiner is used widely in banking, manufacturing, oil & gas, automotive, life sciences, telecommunication, retail, and insurance. Some of the most popular RapidMiner products are –
