Frequently Asked Questions About Database Administrators
Currently, the world generates a staggering 2.5 quintillion bytes of data every single day, and that amount will only increase as the number of connected devices continues to grow.1 Skilled professionals who can collect, store, and make sense of all that data will find themselves in high demand for years to come. Database administration schools can help you get the strong technical foundation you'll need to stand out in this rapidly expanding field.
Think a career in database administration might be right for you? Read on to get answers to common questions about job duties, DBA certification, and earning potential!
What Is a Database Administrator's Job Description?
A database administrator uses software tools to store, manage, and safeguard an organization's data, which can be anything from medical records and payroll details to purchase orders and banking information.
DBAs must make sure that systems are available to those who need access but remain secure from hackers and other unauthorized users. DBAs are also responsible for backing up data so that the information can be recovered if there is ever a power outage, security breach, or hardware failure. They monitor databases and make proactive adjustments to optimize performance and keep things running smoothly.
Some examples of database management systems (DBMSs) include IBM DB2, Microsoft SQL Server, Oracle Database, and MySQL. A DBA uses a DBMS to create and manage databases.
DBAs may specialize in a particular platform; Oracle and SQL Server are the most common. But while the specific knowledge required to work with each platform may differ, the daily activities of SQL Server DBAs and Oracle DBAs are essentially the same.
So, what exactly does a DBA do? Typical tasks include:
- Installing and configuring database servers and software
- Adding and managing user access permissions
- Backing up and archiving data
- Developing and testing disaster recovery plans
- Installing updates and patches
- Transferring existing data to new or upgraded systems
- Tracking database storage usage and planning for future capacity
- Modifying database structures based on business needs
- Troubleshooting issues and devising solutions
In some companies, database professionals may have more specific roles. For instance, some DBAs help design and create databases for specific software applications. Others focus on day-to-day maintenance or performance tuning. The actual job duties can vary depending on each organization's needs.
There isn't just one database administrator career path. Some people start out in programming or help-desk support before moving into a DBA career. As administrators gain experience, they might take on responsibilities such as determining database hardware and software requirements or helping project teams analyze data to help guide business decisions. Some go on to become IT managers.
What Training Is Required?
The qualifications you need to be a database administrator can vary. Becoming a DBA generally requires getting a bachelor's degree in computer science, information systems, or a related field. However, some entry-level roles are open to candidates with associate degrees or certificates. Programs are widely available at vocational schools, colleges, and universities.
A DBA program is designed to give students the technical knowledge that successful database administrators need. For instance, all aspiring DBAs need to be comfortable with Structured Query Language (SQL). DBA training programs can help you become proficient in this database management language. They can also help you learn about networking, database design, performance analysis, and security.
When not part of a degree program, a DBA course is typically focused on teaching administration skills related to a specific platform, such as Oracle or SQL Server. Such courses often prepare students for vendor-specific certification exams, which can enhance your employability (see below).
What Database Certifications Are Available?
Specialized database administrator certification can boost your career prospects. A DBA certification is looked upon favorably by many employers because it demonstrates that you have a certain level of competence in a particular technology.
Certifications are available for a wide range of database management systems. The most popular certifications relate to Microsoft SQL Server, Oracle, and IBM DB2.
Microsoft SQL Server
Microsoft's database certifications come in three tiers:
- Microsoft Technology Associate (MTA)—This beginner-level certification includes a Database Fundamentals exam that covers the basics of storing and manipulating data. It's aimed at people who are new to technology, and it is not required for higher-level certifications.
- Microsoft Certified Solutions Associate (MCSA)—At this level, there are multiple certification options in database administration and development, each of which requires two or three exams. The MCSA can open the door to entry-level roles in IT. You must earn this credential before you can qualify for the MCSE.
- Microsoft Certified Solutions Expert (MCSE)—This advanced level includes SQL database certification called Data Management and Analytics. You will need to have an MCSA designation and pass an exam.
The latest version of the Oracle Database is 12c, although Oracle 11g training and certifications are still available. Keep in mind that when Oracle no longer supports an older version of the database, you will need to upgrade your certification to a version that is supported.
Here are a few of the most common Oracle certifications for database administrators:
- Oracle Certified Associate (OCA) for Database 11g or 12c—This certification focuses on basic operational management skills. To get it, you must pass two exams: one on SQL and one on database administration, specifically for either 11g or 12c.
- Oracle Certified Professional (OCP) for Database 11g or 12c—You must have an OCA credential before you can take the higher-level OCP certification. You must also complete an Oracle-approved training course and pass an advanced administration exam related to the database version you choose.
- Oracle Certified Professional, MySQL 5.6—Becoming certified in the installation, maintenance, and optimization of this open-source technology requires passing one exam. There are no prerequisites, but Oracle offers (and recommends) an exam prep course.
IBM offers three database administration credentials related to its DB2 line of products:
- IBM Certified Database Associate—This entry-level certification focuses on the fundamentals of creating and securing DB2 databases. It involves passing one exam. Optional training courses are available.
- IBM Certified Database Administrator—Aimed at intermediate-level professionals who have experience supporting and administering DB2 databases, this certification requires passing two exams. There are no prerequisites, but training courses are available.
- IBM Certified Advanced Database Administrator—This certification is designed for senior DBAs with significant experience in advanced tasks related to performance, networking, and security. A total of three exams are required.
What Is a Typical Database Administrator Salary?
According to the Bureau of Labor Statistics, the average annual salary for database administrators was $92,030 as of May 2018. Top earners in this field made $138,320 or more.2
The amount you earn can vary depending on where you live. For instance, average DBA salaries are over $100,000 in Washington, California, and Connecticut. New Jersey is the highest-paying state, with an average DBA salary of $110,160.2
