Started with SQL 6.0 Became the DBA because I was the only person who knew “SELECT * FROM TABLE” First job in IT was an entry level developer at 17k per year. Three years later I was Director of IT with a staff of 45. Making a little more than 17k! I wish I had more time to write again. And more money for longer vacations! Been there, done that!

SQL Saturday Pittsburgh What is a DBA? What does that mean??????? IT Professional - The key word here is professional. Great DBA’s rarely do things “good enough”. It’s not in their vocabulary. Installation - You need to perform capacity planning, needs analysis, future requirements, security requirements and obsolescence before you put a disk in and double click “setup.exe” Configuration – What needs to be done to fulfill all of the various requirements? If I change A to 10, and B to 20, will C need to be changed to x? Upgrading – Will the changes affect the existing environment? Will the changes satisfy ever-changing requirements?

SQL Saturday Pittsburgh How does a DBA think? A good DBA considers the problem. A great DBA considers the whole. Training issues The whole database All databases All servers Regarding advice, if you’re last, you’re good. If you’re first, you’re great. Know how the system works under the hood and help people at their own level, but don’t be afraid to stretch knowledge. Teach others and mentor people, but don’t bury people who aren’t ready. Approach DBA tasks with the heart of a developer. SQL Saturday Pittsburgh September 30th 2017
