Key Facts & Information
|Overview||Databases are collections of similar records, like the products a company sells, information on all people with a driver's license for a state, or the medical records in a hospital. Database administrators have the important job of figuring out how to organize, access, store, search, cross-reference, and protect all those records. Their services are needed by law enforcement, government agencies, and every type of business imaginable. Management of large databases is also critical for scientific research, including understanding and developing cures for diseases.|
|Key Requirements||Logical, focused, detail-oriented, and able to communicate well and work in teams|
|Minimum Degree||Associate's degree|
|Subjects to Study in High School||Biology, chemistry, algebra, geometry, algebra II, pre-calculus, English; if available, business, computer science|
|Projected Job Growth (2010-2020)||Much Faster than Average (21% or more) In Demand!|
Training, Other Qualifications
Rapidly changing technology requires highly skilled and educated employees. There is no single way to prepare for a job as a database administrator.
Education and Training
Some jobs may require only a 2-year degree. Most community colleges, and many other technical schools, offer an associate's degree in computer science or a related information technology field. Many of these programs are geared toward meeting the needs of local businesses. They are more occupation-specific than 4-year degree programs.
Many employers seek workers who have a bachelor's degree in computer science, information science, or management information systems (MIS). An MIS program usually is part of a university's business school. MIS programs differ quite a bit from computer science programs. MIS programs focus on business and management-oriented coursework and business computing courses. Now, more than ever, employers seek workers with a master's degree in business administration (MBA) and a concentration in information systems.
Despite employers' preference for those with technical degrees, people with degrees in a variety of majors find computer jobs. One factor affecting the needs of employers is changes in technology. Employers often scramble to find workers who know the latest new technologies. Many people take courses regularly to keep up with the changes in technology.
Jobseekers can improve their chances by working in internship or co-op programs at their schools. There are many internships where you can learn computer skills that employers are looking for.
Certification is a way to show a level of competence. Many employers regard these certifications as the industry standard. One way to acquire enough knowledge to get a database administrator job is to become certified in a specific type of database management. Voluntary certification also is available through various organizations associated with computer specialists.
Database administrators may advance into managerial positions. For example, a promotion to chief technology officer might be made on the basis of experience managing data and enforcing security.
Database administrators must be able to think logically and have good communication skills. Because they often deal with a number of tasks simultaneously, the ability to concentrate and pay close attention to detail also is important. Although database administrators sometimes work independently, they frequently work in teams on large projects. As a result, they must be able to communicate effectively with computer personnel, such as programmers and managers, as well as with users or other staff who may have no technical computer background.
Nature of the Work
Watch this video to meet Leland Chee, the keeper of a secret database called The Holocron, a digital encyclopedia of all the characters, planets, ships, and events in the Star Wars Universe.
The Internet and electronic commerce (e-commerce) generate lots of data. Computer databases that store information on customers, inventory, and projects are found in nearly every industry. Data must be stored, organized, and managed. Database administrators work with database software to find ways to do this. They identify user needs, set up computer databases, and test systems. They ensure that systems perform as they should and add people to the system as needed. Database administrators often plan security measures. Data integrity, backup, and security are critical parts of the job.
Database administrators work in offices or labs. They usually work about 40 hours a week, but evening or weekend work may need to be done to meet deadlines. Telecommuting (working from home) is common for computer professionals.
Like other workers who spend long periods of time in front of a computer, database administrators can suffer eyestrain, back discomfort, and hand and wrist problems.
