Before exploring more about these trending professions in our blog on Data Engineer vs Data Scientist, let’s look at the topics covered in this blog:

What is a Data Science Engineer?

Data Engineers are the professionals who prepare large sets of data for analysis by Data Scientists. They are typically responsible for building data pipelines and collecting reliable data from various sources. Data Engineers form the base of the entire analytical architecture of an organization. These professionals are known for closely working with Data Scientists and assisting them in data analysis and operational tasks. They are skilled in Data and web service integration, database knowledge, data warehousing, and tools like Hadoop and Spark, etc.

Key Differences between Data Scientists and Data Engineers

Now let us understand what are the points of difference between Data Scientists and Data Engineers.

Data Engineer vs Data Scientist: Job Roles and Responsibilities

In the comparison of Data Engineer vs Data Scientist, you need to remember that both the roles have their respective responsibilities in the field of data, but a Data Engineer handles the first operation on the raw data before transferring it to the database of the organization.

Data Engineer vs Data Scientist

Let’s now check out the difference between Data Engineer and Data Scientist roles.

What does a Data Engineer do?

Data Engineers are often sort of Data Architects. They are the masters of designing, building, testing, integrating, and optimizing the raw data for operational or analytical purposes from a variety of sources.

For example, in a car manufacturing firm, a Data Engineer figures out the data that is to be stored in a data schema. Then, he looks for the storage space, also known as Data Warehouse, which is secure, accessible, and reliable. The role performed by a Data Engineer can be divided into 3 categories:

  • Design
  • Build
  • Arrange

Design: They design the entire data architecture on which the Data Scientists work. They work on structured as well as unstructured data and create the base for data scientists to perform analysis and interpretations.

Build: Data Engineers build data pipelines by collecting data from various sources. They are responsible for converting the data into a usable format and implementing and maintaining analytics databases.

Arrange: Data Engineers organize the data so that it can be used in specific analytics applications. Also, they are responsible for performing data cleaning and consolidation.

To be precise, the role of a data engineer can be summarised as follows:

  • Performing data extraction from various reliable sources such as official websites, journals, etc.
  • Transform the data by converting it into an appropriate format and cleaning it by dropping the unnecessary and unwanted elements
  • Store the data in the warehouse

A Data Engineer works on the improvement of data based on the following criteria:

  • Reliability
  • Efficiency
  • Availability
  • Quality

Certification in Bigdata Analytics

What does a Data Scientist do?

After getting the processed data, the role of a Data Scientist comes into play. The Data Scientist uses techniques such as clustering, decision trees, neural networks, etc. that will bring magic to the whole process and, eventually, aid the organization as it will directly impact the decisions and help identify new trends and opportunities and know about customers and the areas of improvement. These professionals indulge in conversation with business leaders to understand specific demands and work with their domain expertise to achieve the desired goals.

The role of a Data Scientist is explained in the following steps:

  • Analyze
  • Test
  • Derive Insights
  • Present

Let us now understand them one by one.

Analyze: Data scientists perform analysis on large sets of complex data to recommend and prescribe the right course of action for significant solutions to business problems.

Test: Data Scientists are also involved in testing whether the applications or models are meeting the business needs and requirements.They monitor the performance of the models to identify whether the goal is being met or not.

Derive Insights: Data Scientists make sense out of the data by identifying trends and hidden patterns in relation to the business goals or problems.These derived insights are used by the management for a data-driven business decision-making process.

Present: A part of the job role of Data Scientists also includes data visualization. Data Scientists communicate the insights and findings to the management in a lucid and understandable language. These skills are collectively called data visualization skills.

Let us understand the roles of Data Scientist through an example. Consider a Data Scientist in an oil and petroleum company who wants to work on the data about the availability of expanding the industry to the Middle West. So the first step that he would take will be to approach the Data Engineer for information regarding geographical topology, government policies, etc. After that, he would apply certain data techniques to generate insights from this data and present them to the top management so that they can make a decision whether to go on with the expansion or not.

Data Engineer vs Data Scientist: Education Background

As both job profiles complement each other, there is one thing in common: If you want to pursue any of these profiles, you should have a background in computer science.

There used to be a requirement for a dedicated skillset as both fields required domain expertise, but now, it is uncommon as there are ample examples of people coming from various other backgrounds, such as biologists, meteorologists, or physicists, making a career in the field of data.

Education Background

Data Scientists often have skills in mathematics, statistics, econometrics, and operations research. They are more inclined toward the business-oriented side than Data Engineers.

Data Engineers usually have a pure engineering base as they are responsible to store and manage data efficiently in systems.
