With the rapid growth and advancement in information technology in the late 20th century, businesses were accumulating reams of data for historical records. At first, few saw the value of this data, but soon it became widely understood that organizations were amassing an extremely useful and valuable resource. Once that realization spread, the construction, storage, manipulation, and management of huge databases became a pivotal function in every organization. Database administrators were at the very heart of this new reality, as they still are today.
Database administrators are information technology professionals that ensure the optimal storage and access to an organization’s data. This is done by ensuring software programs are designed, managed, and maintained to permit rapid access whenever and however needed by authorized personnel. Database administrators also work with cybersecurity professionals to safeguard the data from unauthorized access and damage. Alternatively, database developers are responsible for the design, programming, and construction of new databases. Some organizations treat these two posts as one job, but for the purposes of this discussion, we have separated them as distinct careers. A career guide for database developers can be viewed here.
This guide provides an overview of the database administrator role and lists the steps required to begin and maximize a career as a database administrator. Included is a detailed list of job responsibilities, background, education, and experience required to be successful professional, as well as salary information, and the future outlook for the database administrator job market.
What is a Database Administrator?
Let’s start at the beginning. What exactly is a database administrator? In essence, database administrators (occasionally known as DBAs) have ultimate responsibility for designing and maintaining all aspects of an organization’s data storage facilities.
Database administrators are often tasked with building a new database from the ground up, beginning with the design and construction of application specific customizations to a database platform, and the implementation of the new database. This would transform the role into more of a database developer, with which its often combined. Data input and accumulation methods and protocols must be designed, access permissions granted and monitored, security protocols put in place and monitored, data integrity constantly analyzed, damage repaired, backup methods determined and maintained, program updates implemented, new data sources and data points integrated into the existing database, and new reporting requirements satisfied.
What does a Database Administrator do?
Database administrators are responsible for the storage, organization, presentation, utilization and analysis an organization’s database and database management software. Whatever the information storage needs of a company are, a database administrator strives to meet them. This can include setting up new computer databases or integrating data from old systems to new systems. A good database administrator also needs to respond to the (sometimes constant) change of informational needs, whether it be new types of data being accumulated or different reporting or presentation needs of management. The database administrator must adapt the database software to accept new data points and produce new reports whenever necessary.
Responsibility for maintaining a fully functioning database also lies with the database administrator. Database administrators must regularly perform routine tests and modifications to ensure that a database is performing and running correctly. If a problem occurs, a database administrator must analyze the programs and hardware to determine the problem, and then perform the necessary repairs or alterations. Database administrators also must monitor access privileges, any unauthorized use, and making changes to permissions when required. Coordinating with infosec staff members, database administrators also must update security measures as internal security protocols are adjusted.
Four Steps to Become a Database Administrator
Step 1: Education
Database administrators must be knowledgeable of all aspects of designing, organizing, and maintaining information storage needs for any particular company. A strong generalized background in relational database management systems, including an understanding of structured query language (SQL), is a basic prerequisite for all database professionals. More specific and advanced database skills and knowledge are required to operate specific platforms, including various Oracle products (such as the open source MySQL environment and Oracle itself), Microsoft SQL Server, IBM DB2 and more.
Database administration job openings will usually require an undergraduate degree. Degrees in information technology are the norm, and probably the most appropriate course of study. Bachelor’s degrees in computer science, engineering and even business administration can also gain a candidate entry into database management. Taking as many courses in database administration or management as possible will make the college transcripts more attractive to prospective employers. This may include coursework in several specific database packages, such as Oracle, IBM AS/400, SQL, and ETL. Some employers will hire entry-level database administrators who have a two-year associate’s degree in database administration, or possibly even a certificate in database management or a related IT subject. Some certificates can be acquired even before or during college. And a trade association for IT professionals in training is also available for students – CompTIA Student Membership.
A number of certifications for database administrators are offered by some of the biggest names in tech, like IBM, Microsoft, and Oracle. Most of the vendor-specific certifications available are dedicated to the platforms offered by these three companies because they are by far the most popular database software producers today. Some of the certification programs for specific software frameworks include:
- Microsoft Certified Database Administrator (MCDBA)
- Microsoft MSCE Certified Data Management and Analytics
- Microsoft Certified Solutions Expert: Data Management and Analytics
Oracle has multiple certifications and multiple expertise levels available for each certification. IBM also has several certifications available, primarily for the DB2, and various levels as well. Even if a current job doesn’t require knowledge of Oracle or Microsoft database programs, future opportunities may, so it’s always a good idea to expand technical horizons and enhance the resume with more certifications.
Vendor-neutral certifications, those not tied to a particular database software product, are not plentiful, but there are a few available. Some examples are:
Several colleges and technical schools also offer similar vendor-neutral database administrator certificate programs, as well as undergraduate and graduate certificate programs.
Step 2: Career Path
Entry-level positions are available for candidates with a bachelor’s degree, and sometimes even an associate’s degree or database administration certification. Sometimes called associate database administrator, these entry-level positions can kick off a career in several directions, not just database administrator. If database administration turns out to be the favored path, it can also lead to advancement into these careers:
- information systems manager
- computer systems analyst
- data or database architect
- database engineer
- database developer
- chief information officer
Step 3: Build a network of information technology professionals
As with nearly every profession, networking among industry professionals can be an invaluable aid in building a successful career. This may be especially true in computer science professions due to the constantly changing technologies. Networking and being a member of various industry trade associations can provide countless opportunities to keep current, including conventions, seminars, and other educational offerings often afforded by such organizations. Some of the trade associations relevant to database administration include the following:
- CompTIA Professional
- International Association of Computer Science and Information Technology (IACSIT)
Step 4: Keep up with a changing world
Database administrators must always be acquainted with the latest of innovations in computer programming and database frameworks in order to be effective managers of data storage facilities. The abovementioned trade associations provide excellent access to advancements in technology, as will networking with other professionals. Keeping tabs on the latest announcements and product introductions from the primary database management framework providers, including IBM, Microsoft and Oracle, will mean no surprises with what’s available on the market. Professional certifications may also require period refreshing as products and technologies evolve, so it’s essential to update certifications whenever practical.
