Data leaks

Where Are Your Data Leaks?

It has been almost impossible to avoid reading about the numerous large-scale data breaches reported on a seemingly daily basis. Stories of bad actors getting their hands on personal data are terrifying and always result in bad press for the breached company. However, not all data exposure scenarios make the news, and many can go unnoticed or unreported for years. Data leaks…


PASS Summit 2018

Speaking at PASS Summit 2018

I am honored to have been selected to be a presenter at this year’s PASS Summit coming up this November. I will be presenting a half-day talk entitled Build a Metadata-Driven ETL Repository with Biml and SSIS: Your boss tells you that a new field will be added to one of your vendor’s data files, and asks how long it will…


Temp Tables in SSIS

Temp Tables in SSIS

Temp tables are very handy when you have the need to store and manipulate an interim result set during ETL or other data processing operations. However, if you use SQL Server Integration Services as your ETL tool, you may find some challenges when trying to work with temp tables in SSIS packages, especially in the SSIS data flow. In this…


Business Logic

Managing Business Logic

Encapsulating business logic into data movement and presentation is a critical part of a stable information management strategy. Too often, though, business logic is built and added late in the process, forcing it into whatever nooks and crannies are available.

Trading Data For Convenience

If data is the new oil, then the web is the world’s biggest gas station. Every day a few billion people visit this marketplace and trade some of their personal data for convenience. We tell Google Maps or Waze where we are and where we intend to go. We share (and sometimes overshare) with FaceTwitRedditGram the essential details of our lives…

Using SQL Server Management Studio Projects

Within Management Studio, one can create code projects that make organizing SQL scripts much simpler, and more easily integrate with source control systems. In this brief post, I’ll show the essentials of using SQL Server Management Studio projects for T-SQL code management. T-SQL Code Management…

A Business Lesson from an Oil Change

When I first moved to the city where I now live, I found an oil change place just a couple of miles from my house. The location was convenient and I never had any major issues with the service there, so it became my go-to shop for automotive oil changes and other light maintenance tasks. One day, when I was…


Making a Difference: Andy Warren

Since I started working as a data professional some 15 years ago, I’ve had an enjoyable and successful career. I attribute the successes I’ve had to hard work, a good bit of luck, and having help from others who have walked the same path before me. Today, I want to recognize one of those folks in particular. A Long Line…


Real Time

Do You Really Need Real-Time?

It wasn’t so long ago that the first day of the month was the most common trigger event for updating key metrics. Indicators such as profit, efficiency, bonuses owed, and other markers would be published monthly after that month’s data was tabulated (which may be days or even weeks into the new month). In some organizations, the work required to calculate…

My SQL Server Management Studio Setup

We’re all creatures of habit, and work more efficiently when we know exactly where to find the tools we need. The same holds true with digital tools, and those of us who work with SQL Server will spend a lot of time using SQL Server Management Studio. SSMS has a lot of features, but each data professional will likely use…
