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.
Xamarin.Forms abstracts UI definition into cross platform Xaml, with all controls rendered natively across iOS, Android and Windows Phone. In this session you will learn how define a multi-platform UI once for each of these platforms, binding to data stored in a local DB using the Mvvm pattern, and synchronising to the cloud using Azure Mobile Services. Learn when it is necessary to dive into platform specific code and how to go about this in code and in xaml.
With the upcoming release of Windows 10, there will be new and updated ways to deploy Windows. In this session, we review new recommendations for upgrading existing devices using a simple in-place upgrade process, provisioning tools for transforming new devices into ones ready for enterprise use, as well as updates to traditional deployment tools and techniques (ADK and beyond). We also talk about application compatibility, hardware requirements, and other common deployment questions.
