DAX is not only an expression language, but also a query language and, when it comes to performance, the xVelocity in-memory engine is second to none. Scanning fact tables and performing leaf-level computation happens in a matter of milliseconds. Nevertheless, as with any other language, you can write good DAX or bad DAX, depending on your understanding of the engine internals. This session introduces DAX as a query language, showing the different ways of querying with DAX using real-world data. Some queries will be fast, others will need optimizations. Many practical examples based on common patterns and an analysis of the query plans will show how to get the best out of DAX.
ASP.NET vNext is a lean and composable framework for building web and cloud applications. ASP.NET vNext is fully open source and available on GitHub. ASP.NET vNext is currently in preview, and in this talk Fowler and Edwards will put it all into Context. vNext apps can use a cloud-optimized subset of the .NET framework. This subset of the framework is about 11 megabytes in size compared to 200 megabytes for the full framework, and is composed of a collection of NuGet packages. What does that mean for compatibility? When would you choose vNext and when would you not? You don't have to use Visual Studio to develop ASP.NET vNext applications. You can develop and run vNext on platforms that Visual Studio doesn't run on. But Visual Studio provides the best development experience, and we'll cover ASP.NET vNext both inside and outside the IDE.
You already know the ingredients: Windows Server 2012 Hyper-V, Microsoft System Center, Microsoft Azure and Microsoft Visual Studio. Now, using real-world customer examples and a comprehensive demo, learn how to weave these technologies together into a practical, end-to-end, turnkey solution. The demo shows you how enterprise IT can create a secure, multi-tenant, policy-driven cloud that spans from your datacenter into Azure. You also learn how application owners and developers can use this cloud to deploy, manage and seamlessly move .NET and Java applications between private and public resources (without code changes!) using a solution from Apprenda and Microsoft.
