Databases are common to most modern businesses. There isn't anything on the Internet without a database; anything that requires e-commerce has a database. Technology is always growing and companies in all industries around the globe need database administrators (DBAs) to make sure all information stored on their computers is secure and only available to authorized users.
Armed with the knowledge and experience to write and install computer programs and debug software issues, database administrators are the people who help companies of any size set up, maintain, and secure large volumes of information.
Imagine what you can do by gaining real-world, hands-on experience in database administration. You can develop the skills and knowledge you'll need to create a fulfilling career in this growing high-tech field of developing and managing databases, with a special focus on the popular and top-rated Oracle database solutions.
What Is Database Administration?
Database administration enables you to help companies create new or update existing databases based on their internal data collection needs. A database administrator position offers you a chance to be creative and solve problems in database development and testing by writing software scripts, testing database functionality and keeping company data clean and secure.
In a TechRepublic article titled, "What does a DBA do all day?" Bob Watkins summarized the DBA responsibilities clearly. "It's been said that the database administrator (DBA) has three basic tasks. In decreasing order of importance, they are: protect the data, protect the data, and protect the data."
As a DBA, your first responsibility is always going to be to maintain the integrity of the company's data - because even if a database is fast and accessible, it's useless if the data being accessed is distorted.
In an entry-level role, you'll work closely with managers to learn about the type of data to collect, the form the data should be stored in, and how to make the data available for exporting into reports, for example. You'll learn the ways to verify that the database's integrity isn't compromised and how to keep the data secure. When starting out, you'll receive guidance on implementing data models and database designs by following policies and procedures and be able to grow your expertise through daily experience.
As a DBA, you'll also focus on monitoring and maintaining a high level of system performance. Database administrators are responsible for performing regular system backups so no data is lost during a power outage or other type of disaster. You'll also work to ensure that the data being captured is reliable, error-free and available at any time.
Online system security is important, particularly when it comes to companies that capture personal and financial customer information, which is almost every e-commerce business. In your position as a database administrator, you'll have a chance to develop applicable security measures when designing new, or helping to update existing, databases.

If you love the idea of building or administering system databases for an organization, and have the desire to learn more about computer software, focusing on database administration will give you a chance discover what you enjoy most.
If you're already in a role that allows you to play with technology and learn about software programming and databases, obtaining advanced education and hands-on experience can give you the boost you need to help you seek advancement in your current company or help you transition into a new company.
It's sometimes true that the more you learn, the more you'll find you want to learn. Once you start learning more about databases, you can expand your horizons with additional classes that interest you. "Definitely explore all of the options available," Tofteroo said. "Take additional IT classes as electives. The deeper your understanding, the more enjoyable the classes will be."
As a DBA, your ever-expanding knowledge will help you troubleshoot issues as they arise by learning how to identify the problem and learning how to correct it without losing data. As a DBA, you won't be bored if you enjoy solving problems or puzzles particularly in regard to learning how data is collected, processed, reported and maintained.

Charles Fulgham's degree in database administration took him all the way to the FBI. Because of that he can't say much about what he does there beyond "database-related work on behalf of the Department of Justice." But he said studying online immediately paid dividends at work. He remembered one meeting at work focused on issues on the office's computer network. He'd learned in a course he was taking at the time about a tool called WireShark and suggested using it to read the network's data packets and was able to find and solve the networking problem.
"That more than anything is really valuable stuff," Fulgham said. "I know that i was able to take what I learned a pretty much apply it immediately on the job. I'm really glad I did it."
You may also choose to continue your education by pursuing an Oracle certification, advance through a master's degree in IT, or even transition into a related field, such as cyber security. You'll have options to choose from and new interests to pursue.
