When someone goes on a rant about something they truly feel strongly about – good or bad, my typical joking response is “You’re being a little wishy-washy about this. Tell me how you really feel.” I recently had a conversation with co-workers about surrogate primary keys and realized I need to use that line on myself.
So let me tell you how I really feel about surrogate primary keys. Where’s my soapbox?

It’s another T-SQL Tuesday. Thanks to Wayne Sheffield (b|t) for hosting this month. His T-SQL Tuesday challenge is to write about Brick Walls we have faced. (If you are unfamiliar with the T-SQL Tuesday party, check out the website for the full backstory.)
It took me a bit to figure out what to write about for this topic. But that’s not the type of brick wall I want to post about today.
The Brick Wall:
I was working with a highly transactional system. The table with the most writes was also the table with the most reads. To add to the problem, the data being updated the most was the same data we need to read the most. The next set of popular tables, i.e. the next most read and updated tables, had triggers that used the most popular table for some of the data needed. As you can guess, we had a lot of deadlocks in our system. Oh, did I mention that this was running SQL Server 2000?

I want to talk a little about database design patterns. When working with a relational database, there are a couple of patterns that exist to help you normalize your data. I think one of the most useful patterns in this is the supertype-subtype relationship.
You don’t see a supertype-subtype relationship defined as such when you’re looking at the physical database. You’ll only see it explicitly in the logical data model. So what is the pattern and how do you know that you have one in your database?

Happy T-SQL Tuesday #102! The challenge for this month is from Riley Major (b|t). His challenge is to think about how we can give back to the community. (Check out his blog invite or the T-SQL Tuesday website to find out more details about this monthly blog party.)
The list of suggestions that Riley put together is quite an impressive one. It’s a great reminder that there are so many ways to get involved in the community.
I’ve started doing several things on the list over the past year – speaking, taking on the T-SQL Tuesday challenges, getting involved with the local user group – so I’m definitely going to commit myself to doing more of that. Maybe I can “up my game” and submit to a SQL Saturday in a city that I have to fly to or even submit a session to present for a virtual user group or a bigger event like GroupBy or 24 Hours of PASS.
At my new job, I’ve been told there are opportunities to do “lunch and learns” and I’ve been told to encourage my co-workers to join me at the local user group meetings. It’s kind of a no-brainer to do those.
But of all the things on the list, I definitely would love to find a way to pay forward the support I’ve gotten from members of the community to others who need it. A few people have come to me asking for advice or to be sounding board. As happy as I am to help out, I still feel like there’s more that I could do in this area. One concrete thing I think I can do is volunteer to help the first timers at PASS Summit as part of Buddy Program, if they continue that program again this year. But I’m going to keep looking to find other opportunities to help support others as they need it and in general feel like I’m being a better citizen of our #sqlfamily. I know they’re out there, but I just need to find the way that I can contribute.
As I was putting this list together, I realized that these examples are little things that I can do. And that’s OK that they’re little things. I think that’s important thing to note for those who are thinking about how they can start to give back to the community. One of the great things that Riley’s original list proves is that not every way to give back to the community requires big gestures. If you’re not someone who’s comfortable stepping into the limelight or jumping in with both feet (or whatever other catchphrase fits), there are still a lot of behind the scenes ways to contribute. There is a place in this community for that special passion you have and this community wants you to share with us.
Thanks to Riley for hosting this month’s topic! And thanks to all those who are currently doing so much to support our community and those are going to take on the challenge to step up their involvement! And if there is something I can do to help out, please let me know….
I was talking with some people after a user group meeting and over the course of conversation, I was asked what I do. I said my official job title was Senior Database Architect. It then turned to why my blog is called “Deb the DBA” if I’m a database architect. Perhaps “Data by Deb” would be a better name? It’s not the first time the “DBA” part of the blog title has gotten attention. But all of this definitely got me thinking…
As I write this post, my title is no longer a Senior Database Architect. I’m about to start a new job with the title of Senior Database Developer. My title the last time I switched jobs was Senior Database Administrator. Continue reading “Insert Title”
It’s T-SQL Tuesday. But it’s not your ordinary, normal T-SQL Tuesday – it’s the 100th T-SQL Tuesday, which is a pretty significant milestone. This month, our host is the creator of this monthly blog party, Adam Machanic (b|t). Adam, thank you for introducing something that has inspired the community for so long.
Our challenge this month is to think about what the world would be like for T-SQL Tuesday #200. I can barely predict what’s going to happen in the next 10 days and I definitely don’t have the insight of “The Simpsons” writers, but I thought I’d give this a try – in terms of databases at least.

Just call me Jon Snow, because like him, I know nothing.
Or at least, that’s how I feel. In many ways, I feel like a light has gone on over my head. Recently, I’ve been looking something that I’ve been working with for a long time and I feel like I’m really able to understand it.
I’m talking about execution plans. I use them all the time. But lately, I feel like I’ve not been using them correctly at all. I always try to go to as many different sessions that cover execution plans to make sure I know how to read them properly. Despite my best efforts, I’m not sure where I went wrong. But I feel like I should share where I’m starting to get things right.
