1. What’s the role of a Database Administrator?

Database administrators, often known as DBAs, ensure that data analysts can simply use the database to locate the information they require and that the system functions properly. DBAs may collaborate with an organization's management team to understand the company's data requirements and to establish the database's goals.

To become a database administrator, you need to work with databases. And this requires a thorough understanding of complicated systems, where even slight errors can result in huge issues.

For example, if a customer's credit card information is mixed up, he or she may be charged for a purchase that he or she did not make. Database managers employ software to interpret data and arrange and organize it into meaningful patterns. The data is subsequently saved in databases that these employees administrate, test, and maintain. When issues develop with a database, administrators must be able to diagnose and resolve them.

A database administrator's responsibilities include the following:

  • Identifying user requirements for database creation and administration

  • Ensure that the database runs smoothly and without errors.

  • When necessary, making and testing changes to the database structure

  • Updating permissions and maintaining the database

  • Transfer the old database to the new one

  • Preventing data loss by backing up and recovering data

And there are two common specialties of DBA:

- System DBAs: in charge of a database's physical and technical components, such as installing updates and patches to fix bugs. They usually have a background in system architecture and verify that a company's computer system's database functions properly.

- Application DBAs: look after a database that was created for a single application or a group of related applications, such as customer service software. They may write or debug programs using complicated programming languages, and they must be able to handle the components of the applications that interact with the database. They do all of the functions of a general DBA, but only for their application.

2. How can you become a Database Administrator?

To become a database administrator, you can take one of two routes: Starting in a general ICT field at a good recruitment agency like JT1. You can start a career such as help desk support or development and gradually become more adept in database administration, or (more typically) starting in a general ICT field, such as help desk support or development, and gradually becoming more proficient in database administration.

In any case, being a skilled database administrator does not happen quickly. One must first learn specific skills that are also required in most ICT jobs:

  • Curiosity and a strong will to learn: Curiosity and drive will ensure that your database administrator job does not stagnate. Only your ability and will to continue learning new things will keep you from falling behind in the IT profession.

  • Excellent troubleshooting skills: When faced with a problem, especially one you haven't seen before, the ability to think through the potential causes and then eliminate or follow them rationally to the end is critical. A good DBA can spot a problem and immediately figure out what's causing it, as well as alternative fixes.

  • Logic, common sense, and a good memory: It's also vital to have the innate capacity to think logically utilizing an elimination-based technique, as well as a solid recall. This includes the capacity to recall technical information about numerous systems and platforms important to your setup, such as how to expand the size of a table in a SQL Server database, how to add a new drive to a Linux server, and how to delete a user from a PostgreSQL database. Similarly, keep in mind a few unique details regarding your environment (do you work on a LAN or WAN? What are the database administrator passwords? Do you have a large number of users? When is the next database audit scheduled? Where do you store the backup?

3. How long will it take to become a Database Administrator?

You need to look at the math to figure out how long it will take you to become a database administrator. The assumptions below are very broad database administrator education requirements for a new DBA, not for someone who is already a database administrator and wants to change positions:

  • A four-year college degree in an IT discipline is required by most employers.

  • Following that, database administrator training and certifications are required. Technical training and database administrator credentials are also required to become a skilled DBA.

  • It will take at least two to four years of full-time employment in a hectic workplace to become relatively proficient as a DBA.


Becoming a database administrator is not too hard, but you need to keep learning new things every day. A great database administrator is one who has a great memory, great problem solver skills, and if you want to have one of them work for your company in Vietnam, a recruitment agency like JT1 can help!
