I recently had a student conducting a career study/project contact me with questions about my career and the choices I made to get where I am. I'm certainly not perfect by any stretch of the imagination, but I give it my all. I hope that my answers to his questions helped inspire him to go after his dream, whatever it may be (even if it's not to be a DBA).
Student: What is the title of your career?
Me: My career title is essentially Database Administrator. My current job title is Tier III Database Administrator (Senior DBA), and I specialize in architecture/infrastructure engineering for Microsoft SQL Server.
Student: How many years have you had on the job?
Me: I've been working with databases in general for about 15 years, and specifically SQL Server for over 10 years.
Student: What attracted you to this career? Did you have an experience that influenced your decision to choose this field?
Me: I started out my professional career in a small call center providing phone support. I gradually worked my way into more of an IT/Help Desk role and then up to Network Engineer. When I started working as a Network Engineer, I happened to be the only one on the team that wasn't scared of the database servers. As I learned more about SQL Server, I realized that I really liked working with it and I wanted to learn more about it. There is a bit of an infinite cycle there, the more you learn about a subject, the more you realize how much more there is to learn about it. Once I realized that I was more passionate about working with data and SQL Server than anything else, I made that my primary focus.
One thing that has really solidified my decision in my career is the tremendous sense of community and even family when you work with SQL Server. There are plenty of people who are more than happy to take some time out of their day to help you out if you have a problem, or just want to chat. Check out the #SQLHelp and #SQLFamily hash tags on Twitter for just a couple examples of what I'm referring to here.
Student: What type of education or training is required for your job?
Me: A strong foundation on math, and logic/analytical thinking
comes into play when working with SQL Server. There are multiple
different job roles/responsibilities/career paths in working with SQL
Server (and even more if you consider other database platforms like
Oracle, MySQL, Hadoop, etc...). Programming classes (specifically T-SQL
classes would be ideal) would also help you to prepare for working with
SQL Server. Almost every aspect of SQL Server requires some
familiarity with T-SQL code and the logic behind structuring a query and
getting it to perform. While it's pretty obvious that a SQL developer
needs to have strong T-SQL coding skills, as a DBA, I also need be very
familiar with T-SQL coding so that I can tune queries that no longer
perform well.
One way to get free training is to attend local events or online training. I am the president of the Rochester PASS SQL Server User Group and we have monthly meetings during most of the year (I skip Summer and December).
More
online training can be found in the form of virtual chapters (periodic
webinars/meetings online). More virtual chapter information can be found
here: http://sqlpass.org/PASSChapters/VirtualChapters.aspx And finally,
there is a one day SQL Server mini-conference (appropriately named SQL
Saturday) coming to Rochester on Saturday, May 16th.

Student: What specific skills are needed to do the job?
Me: I think my previous comments speak to this well, but I will also add
that there are times that you need to have tenacity and focus in order
to solve problems (this applies to many other careers than just a career
in SQL Server). I am a highly distractable person, and I find it hard
to focus on a problem at times, but I still manage quite well. It is
just more difficult for me to go heads-down and focus solely on a
specific issue.
Student: What are your major daily tasks?
Me: Major daily tasks for me include reviewing alerts (backups, critical
errors, performance issues, failed scheduled jobs, etc...) from the
database servers (and other infrastructure alerts like storage and
network). Typically our Junior and Mid-level DBAs handle those tasks,
but I will also keep an eye on these so that I have a good understanding
of the health of our servers. I am an escalation point for major
issues and incidents. And my typical role (outside of problem/incident
response) is project based. We recently migrated to a new SAN and I was
responsible for migrating all the database files from the drives
associated with the old SAN to the drives/paths on the new SAN. I'm
also working on a project to upgrade our infrastructure to SQL Server
2014 (our last production servers will upgrade this weekend and next
week). I also provide specifications for ordering new server hardware
and balancing server loads and a host of other tasks. No two DBA jobs/roles
will be exactly the same, but the career is extremely rewarding.
Student: What do you like most about your job and why?
Me: I love working with other people and learning new things. I learned a long time ago that even after you graduate and you are "done"
with school, you never stop learning. The best employees make sure
they're staying up to date on the technologies that they work with so
that they can provide the best solutions to the problems that they
face. I love working with data! I was a math and science geek in
school and college, and that really helped me prepare for a career
working with data, servers and code.
Student: What are some dislikes or frustrations you have and why:
Me: One of my biggest frustrations is that when you work with people, you will always
find that one person that just does not understand how things really
work, and won't take no for an answer. Like if someone puts in a
request that would require a week worth of work (and that's assuming that you drop everything else and focus on just this one request, which is likely never the case), and
then asks if it can be done in a day or two. Poor planning on their
part doesn't always necessitate an emergency on mine, but sometimes it
does. This gives me an opportunity to discuss the situation with the
person requesting the task, and we can set proper expectations (that's a
critical point, make sure that you understand what is required of you
and that the person requesting it understands what and when they can
expect a response). However, you're always going to need to work with
other people (management, team members, customers, etc...), so
interpersonal skills are a must.
Student: How do your perceive the future of this field in terms of expanding opportunities and security?
Me: Technology is always changing, and you need to continually learn
about the products you're working with (that way you don't become obsolete). SQL Server is not going away any time soon, but it is
adapting to fit more modern business needs. I go to the premier SQL
Server conference every year, the PASS Summit.
There have been a lot of security improvements in SQL Server over the
years, including integration with Windows Active Directory, encryption,
and multiple methods to protect your data while in-flight (in memory) or
at rest (on disk). I am a big advocate of least privilege. Only give
the minimum amount of people the minimum permissions that they need.
However, depending on the situation, that is not always easy, or
possible (there are exceptions to every rule). If you work with any
sensitive data (credit cards, Social Security numbers, Dates of Birth,
etc...), you will be audited on how you handle and protect the data.
The more important the data, the more steps you need to take to protect
it (and the more paperwork you need to fill out to prove that it is
protected).
Student: Has the job changed since you began? if so please elaborate:
Me: There isn't much in the technology field stays the same for very long,
and SQL Server is no exception. Apart from the product changes already
mentioned, one of the biggest changes is that the amount of data that I
work with has done nothing but grow. When I first started working with
Databases, they would fit on a floppy disk (just a few hundred KB).
Currently, I'm working with databases that are multiple terabytes (our
largest single database is almost 4TB, but I know others that work with much larger databases), and this results in a lot more
data flying around when you're querying the database. You have to do a
lot more tuning to queries that are hitting large amounts of data in
order to get them to perform well.
Student: Is there anything I currently can do to prepare for this career?
Me: I'd
recommend you check out this blog series for the accidental DBA:
https://www.sqlskills.com/help/accidental-dba/ Gaining an understanding
of relational databases and their structures will definitely help.
Personally, I had no clue when I first started working with SQL Server,
but I was able to learn as I went along.
Student: Is there other information that may be helpful?
Me: The bottom line is to find something you love to do. To do that,
you have to try a lot of things. I didn't discover my passion for SQL
Server until over a decade into my professional career. Don't be afraid
to try new things. Don't be afraid to learn new things. And don't be
afraid to make mistakes. That's how we all learn.
One of my favorite quotes by Albert Einstein is, "Anyone who has never made a mistake has never tried anything new." Don't be afraid to give it all you've got to follow your dream. You
may make mistakes, but you'll never wonder, "What if I had just..."
No regrets! I know I can certainly say that about my career.
To my new friend Hunter, I wish you the very best of luck in whatever you do. Find your passion and give it your all!
