Database Architects and Database Administrators (DBAs) have essential roles in managing and organizing data systems, but their duties differ a lot. Database Architects design and structure the databases, while DBAs handle daily maintenance and performance.
The Bureau of Labor Statistics reports that DBA jobs will increase by 9% from 2021 to 2031. This number shows the growing need to manage data in today’s business scene.
As businesses grow worldwide and handle huge amounts of data, it’s essential to understand these roles to optimize database design and maintenance. Whether you’re hiring locally or tapping into the global talent pool, knowing the right position for your data management needs can have a big impact on your company’s productivity.
Not sure which role is the best fit for your company’s data needs? In this article, we’ll explain the main differences between Database Architects (DAs) and Database Administrators (DBAs) to help you make the right choice.
Database Architect vs. Data Architect – The Key Differences
While there is some overlap between both jobs, there is a major difference between database architects and database administrators.
Database architects (DAs) plan, design, and develop the architecture of a database system, focusing on the strategic implementation of new technologies and systems. Database administrators (DBAs), on the other hand, maintain and operate the existing database systems.
Database architects must have a high level of technical expertise, as they are responsible for ensuring the most efficient and secure data systems. Database administrators, however, must have the ability to manage and use the system, as well as troubleshoot any technical issues that may arise.
Let’s go into more detail about each role.
Put simply, a DBA manages and optimizes the performance of existing databases, while database architects design and implement new database systems.
What is a Database Architect?
If your data isn’t organized or secure, it’s impossible to make use of that data efficiently. This is where a database architect steps in.
A database architect’s role involves creating and designing a database that meets a company’s specific needs. They begin by studying and analyzing their employer’s objectives, goals, and current data infrastructure, identifying areas for improvement. To achieve this, they:
- Developing the models needed to ensure both scalability and security and then implement and test them.
- Ensuring that the database meets any industry regulations and data security standards when dealing with sensitive data.
- Creating technical documentation pertaining to a database’s functionality, its ancillary tools, and how they work together to provide all the needed functionality.
In simpler words, they map out how the database should look and work.
