A career in data science is blooming and has been in high demand in recent years. Companies continuously generate, collect, and analyze big data to run their business effectively with data-driven insights. The two significant aspects of data science are data analysis and data engineering. These data science fields offer better salaries, job positions, benefits, and career growth.

Both cover big data visualization concepts and derive meaningful insights to make informed decisions for business. Therefore, the importance of data analysis and engineering increases. Understanding the critical differences between these roles is essential, and you should be able to comprehend the full potential of both professions. To understand data analyst vs. data engineer, have a look at this top comparative guide.

Data Analysis Overview

Data analysis is a process of analyzing big data and deriving actual patterns from it. Those patterns are further analyzed and used to obtain meaningful insights. These insights are used in business operations, competitors’ strategy building, and obtaining customer information.

Once the company obtains this information, it can easily choose the best course of action for its existing problems. This will lead to greater business revenue and growth. Data analysis is a highly sought-after skill that many companies require.

Who is a Data Analyst?

A data analyst is a professional who analyzes data and performs data analysis techniques to help a company gather meaningful information. They collect and store big data on market research, logistics, and sales numbers. They use their technical ability to maintain data accuracy and quality. With data analysis, facts and trends of data are identified and processed.

The business stakeholders use these insights to make informed decisions for the company. As a data analyst, it is your duty to scrutinize information from different analytical tools like Apache Spark, Tableau, Power BI, and Excel. If you prepare to clear the data analyst certification exam, you can learn about it and its tool through the PL-300: Microsoft Power BI Data Analyst CCSLA prep course.

Data Engineering Overview

Data engineering is also very similar to data analysis but has certain differences. Data engineering is the process of digging and collecting information from data. Data analysts analyze these data, but first, it is the responsibility of data engineers to convert big data sets into ready-to-analyze format.

The data engineering process is more of a practical application-based concept. This concept is slowly getting popular, and today, many companies use it for their functions. For example, automobile companies use this concept in developing automatic vehicles, where self-driving cars make decisions to take turns or read road signs. Data engineering helps recognize traffic and interpret the vehicle’s movement and pedestrians by choosing the appropriate option.

Who is a Data Engineer?

It is important to understand data analyst vs data engineer roles since they are two different professionals. Data engineers’ job is to transform data into ready-to-analyze format. This involves various steps and processes like compilation and installation of database systems, building strategies for disaster recovery management, and writing complex queries. Data engineers create data set processes like mining, acquisition, modeling, and verifications.

To become a data engineer, you must understand better scripting languages and tools like MySQL, MapReduce, Pig, PostgreSQL, and Hive. These tools will help enhance your skills.

However, one can classify the role of a data engineer into three categories, such as:

• Generalists: They are employed in small companies, and they work in data processing and managing big datasets.
• Pipeline-centric: Data engineers work in mid-sized companies and handle complex data sets. They closely monitor data and help data scientists transform it into useful formats.
• Database-focused: Data engineers of this category work in large companies where they manage the flow of data and data warehouses (multiple databases).

Data Analyst vs Data Engineer: Key Comparative Highlights

To understand data analyst and data engineer differences, you must know their individual roles and responsibilities along with the required skillsets, career paths, and salary payout. Let’s discuss all these aspects one by one in this guide.
