SQL Developer vs. Data Engineer: What Are the Differences?

Learn about the two careers and review some of the similarities and differences between them.

SQL Developers and Data Engineers are both in high demand due to the increasing popularity of data-driven decision making. Though their titles are similar, these positions have different responsibilities. If you’re interested in a career in data, understanding the key differences between these roles can help you decide which one is right for you. In this article, we discuss the duties of a SQL Developer and a Data Engineer, and we explain how their skillsets differ.

What is a SQL Developer?

SQL Developers are responsible for designing, developing, and maintaining the databases that power the applications we use every day. They work closely with application developers to ensure that the data stored in the database is well organized and easy to access. SQL Developers write and optimize SQL queries that are used to retrieve data from the database. They also design database schema that define the structure of the data stored in the database. In addition, SQL Developers often develop tools and scripts to automate various database tasks.

What is a Data Engineer?

Data Engineers are responsible for developing, testing and maintaining the data systems that allow organizations to effectively store, process and use data. They work with Data Architects to design data models, and with Data Analysts to understand business needs. Data Engineers build the ETL processes that extract data from various sources and load it into the data warehouse. They also develop data integration solutions, data quality control mechanisms and data security measures. Data Engineers typically have a strong background in programming, databases and data mining.

SQL Developer vs. Data Engineer

Here are the main differences between a SQL developer and a data engineer.

Job Duties

One of the biggest differences between a database developer and a data engineer is the type of duties each role carries out. Database developers are more focused on creating, maintaining and repairing databases that companies or organizations use. They’re also responsible for ensuring that the databases function properly and meet the needs of the people who use them. Data engineers work alongside other engineering teams to implement the databases developed by database developers. Additionally, they often help with the design of databases and ensure that the systems in which they’re implemented remain effective and efficient.

Job Requirements

SQL developers and data engineers typically need a bachelor’s degree in computer science, information systems or another related field. They also need to have experience working with SQL databases and developing software applications. Some employers may prefer candidates who have a master’s degree in computer science or a related field. Additionally, many SQL developers and data engineers pursue certifications through the International Association for Computer Information Systems (IACIS) or the Institute for Certification of Computing Professionals (ICCP). These organizations offer training programs that teach professionals how to use SQL databases and other tools they might need on the job.

Work Environment

Both data engineers and SQL developers work in an office setting, but their work environments can differ. A data engineer may spend most of their time working on a computer to create new programs or update existing ones. They also may travel to different locations to meet with clients and collaborate with other employees.

A SQL developer typically spends more time sitting at a desk writing code than a data engineer does. However, they may also need to attend meetings with clients and colleagues to discuss projects and receive feedback.

Skills

Both SQL developers and data engineers use their technical skills to develop databases that meet the specific needs of their company or client. They also both use their analytical skills to understand the data that will be stored in the database and how it can be used.

SQL developers typically use their programming skills to write code that will create the structure of the database, as well as the queries that will be used to extract data from the database. Data engineers usually use their engineering skills to design and oversee the construction of the database. They may also use their coding skills to automate some of the processes involved in maintaining the database.

Both SQL developers and data engineers need to have strong problem-solving skills to be able to troubleshoot issues that arise with the database. They also both need to be able to work well independently and as part of a team.

Salary

SQL developers earn an average salary of $90,207 per year, while data engineers earn an average salary of $113,717 per year. Both of these salaries can vary depending on the size of the company, the location of the job and the level of experience you have prior to pursuing either position.
