You’ve probably heard the expression, “Data is the new oil.” It’s a nod to the reality that data is incredibly valuable as the fuel that drives our modern economy. Working behind the scenes are the skilled, in-demand database developers who help make our data-driven world go ‘round.
With salaries that often reach six figures, the database developer career path is an outstanding opportunity for those with the right aptitude, education and experience. Read on to explore database developer responsibilities, career and salary outlook, key skills, certifications, education and more.
What is a Database Developer?
A central role of the database developer is to help organizations improve the way they utilize data to enhance operational efficiency and uncover valuable business insights and potential opportunities.
To extract optimal value from internal and external data, the data must be organized and made accessible using systems that require both creativity and technical skill to build and maintain. This is where the database developer enters the picture.
According to Database Star, “A database developer is an IT professional who is responsible for creating databases and database software.” Furthermore, “They design databases and work on the code that sits between an application and the data in a database.”
What Does a Database Developer Do?
While the roles and responsibilities of a database developer vary depending on the position and employer, there are standard processes that most database developers can expect to be a part of when working in this field.
The fundamental role of a database developer is to research and analyze an organization’s information needs and, subsequently, to convert the findings into an efficient programming code that accommodates those needs.
Oracle Corporation explains, “A database developer creates databases to suit business needs and improves existing databases by expanding their range or functionality,” adding that professional database developers may also be tasked with making decisions “related to appropriate database languages and technologies, while ensuring development projects comply with database rules.”
According to Oracle, typical database developer responsibilities may include:
- Retrieving data for reports
- Creating, modifying and removing data as required by a specific application
- Designing or updating databases
- Developing new database applications
- Converting legacy applications to work with a specific database setup
Database Developer vs. Database Administrator
Database configuration and management often include a team of professionals who carry out different functions. Closely related to the database developer role is the database administrator (DBA).
Discover Data Science reports that “at the center of almost every organization’s information storage and data mining operations are the database developer and database administrator.” Although these two positions both work closely with database systems, their day-to-day responsibilities are quite different.
What’s the Difference Between a Database Developer and a Database Administrator?
While database developers are responsible for developing new database applications and improving the functionality of existing databases, DBAs are primarily focused on maintenance tasks that ensure databases are secure and run smoothly on a daily basis. Developers are less concerned with those daily maintenance tasks and more focused on optimizing the way the organization uses data.
A database developer can expect to carry out the following tasks daily:
- Designing new databases to satisfy customer and user needs
- Developing database code to carry out specific tasks, such as extracting data for reports, implementing updates or removing data
- Updating existing databases
- Generating business reports based on database insights
- Enforcing database standards and requirements for new IT and business applications
- Establishing IT documentation for new and existing databases
|Job Title||Database Developer||Database Administrator|
|Education Requirements||Bachelor’s degree in computer science or related field, master’s degree required by some employers||Bachelor’s degree in computer science or related field|
|Median Annual Pay||$92,686||$91,249|
|Job Focus||Developing databases and modifying existing databases to better serve business needs||Maintaining database functionality and monitoring daily operations|
|Job Growth Outlook (2020-2030)||9% (faster than average; includes all database administrator and architect roles)||9% (faster than average; includes all database administrator and architect roles)|
Please note that salary numbers will fluctuate based on the latest data.
Database Developer Education Requirements
When hiring database developers, most employers prioritize applicants who have earned a post-secondary degree. Zippia reports that 68.5% of database developers hold a bachelor’s degree, and 19.2% of database developers have earned master’s degrees. While it is possible to become a database developer with an associate’s degree or even a high school diploma, the overwhelming majority of database developers hold bachelor’s degrees or higher.
Selecting the right major is an important step in becoming a professional database developer. According to Zippia, bachelor’s degrees in computer science are the most popular route, with 30% of database developers holding this type of degree. However, it is common for database developers to have bachelor’s degrees in other related fields, such as engineering, information technology, mathematics and even business administration.
No matter which route you take when selecting your major, you should complete as many courses in database-related subjects as possible to impress potential employers. The most beneficial course of study will consist of classes in various database packages and programming languages, including Microsoft, Oracle, IBM, SQL and ETL.
If you’re hoping to climb the career ladder in the database development industry, consider graduate studies. Keep in mind that more advanced positions in this field may require a master’s degree, and sometimes even a doctoral degree.
A master’s degree in data science, such as the online Master of Science in Applied Data Science, provides students with a solid foundation and technical skills vital to the success of a prospective database developer.
