  2. May Meeting: APPLY Yourself

    May 05, 2016

    May 05, 2016

    Presented By: Kevin Feasel

    Microsoft introduced the APPLY operator in SQL Server 2005. This under-used, non-standard operator can help us solve a number of common (and not-so-common) problems with elegant code which performs well. We will look several problem spaces in which the APPLY operator shines, such as joining to table-valued functions, getting the top N child records for each parent record, string splitting, and word matching. With the use of these examples, we will gain a deeper understanding of when to use the APPLY operator.

  3. April Meeting: Managing the Internet of Things, Ingesting Data at Scale

    April 07, 2016

    April 07, 2016

    Presented By: Sidney Andrews

    Our web services and applications can now be connected to millions of devices simultaneously and are still expected to perform admirably. For line-of-business data, this is an exercise where we scale our database. What about our other smaller, more frequent data? How do we handle billions of telemetry transactions from millions of devices? In this talk we will explore the Lambda Architecture design and how we can split the processing of our data so that we have both immediate feedback from our telemetry and long-term analysis. We will first explore the Event Hubs service as an endpoint to capture our telemetry. For speed, we will look at how we can use Stream Analytics to create a slice of our telemetry averaged over time and then dump that data into SQL Database. For completeness, we will look at options such as SQL Data Warehouse and how they can allow us to perform advanced analytics over our complete, raw data.

    February 04, 2016

    February 04, 2016

    Presented By: Kevin Griffin

    Does your ASP.NET application run slowly? Don't worry, you are not alone. Over the past 15 years, ASP.NET has grown to make some of the most mundane web development tasks non-issues. Applications are rapidly built and deployed, but often there is not any time to evaluate the performance indications you might be missing. Sometimes the smallest tweak to an application can have the largest effect. In this presentation, you will learn about 20 "quick wins" for almost instantly making your ASP.NET applications more performant. Some of these tips are so simple, you could push them live into production before the talk is over.
