The SQL Server community is really engaged. They are an active bunch on Twitter, Facebook and LinkedIn, they help each other on forums, they attend conferences. But that isn’t enough interaction – the community started a grass-roots effort to hold local conferences on a Saturday. Free conferences. Odds are there’s one near ...

A new term - well, perhaps not that new - has come up and I’m actually very excited about it. The term is Data Scientist, and since it’s new, it’s fairly undefined. I’ll explain what I think it means, and why I’m excited about it. In general, I’ve found the term deals at its most basic with analyzing data. Of course, we all do that, and the term ...

Last week Microsoft announced several new offerings for “Big Data” - and since I’m a stickler for definitions, I wanted to make sure I understood what that really means. What is “Big Data”? What size hard drive is that? After all, my laptop has 1TB of storage - is my laptop “Big Data”? There are actually a few definitions for this term, most ...

I got an e-mail from someone that has an interesting situation. He has 15,000 customers, and he asks if he should have a database for their data per customer. Without a LOT more data it’s impossible to say, of course, but there are some general concepts to keep in mind. Whenever you’re segmenting data, it’s all about boundary choices. You have ...

Database Schemas are just containers – they aren’t users or anything else – think of a sub-directory on the hard drive. In early versions of SQL Server we “hid” schemas, placing all objects under “dbo”, which gave the erroneous perception that Schemas are users. In SQL Server 2005, we “un-hid” or re-introduced schemas within the database. Users ...

I do a presentation (and a class) called ''SQL Server for the Oracle DBA''. It's a non-marketing overview that gives you the basics of working with SQL Server if you're already familiar wtih how Oracle works. This class and these links DO NOT help you with ''Why should I use Oracle/SQL Server instead of Oracle/SQL Server'' - I'll assume you're ...

Don’t be afraid of that title – I’m not talking about Six Sigma or anything super-formal here. In many organizations, there are more folks in other IT roles than in the Data Professional area. In other words, there are more developers, system administrators and so on than there are the “DBA” role. That means we often have more to do than the ...

I was working this weekend with a fairly simple Excel spreadsheet, and I had to decompose one cell in it out to three columns in a SQL Server table. There are tools within SQL Server Integration Services (SSIS) that should be able to do that, but I just couldn’t find my way around them properly. I’m not as familiar with SSIS as I would like to be ...

Saturday I volunteered at a work-day at our church. Our building is one of the first buildings built in this area of Washington, so it’s a beautiful old structure, which of course means there’s lots of maintenance. I’m fairly decent with tools, I’ve done some woodworking in my day, and I’ve even rebuilt a car or two. But working on a structure ...

I’m a big fan of code that writes code – most of the time. For instance, whenever you use the “templates” feature in SQL Server Management Studio (SSMS) or the Maintenance Wizard, you’re using code that writes other code. There’s even a trick of writing Transact-SQL (T-SQL) code that in turn creates other code. But there is a class of code ...
