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.
The third installment in our series on Software Defined Networking (SDN) with Lync continues with an exploration of Quality of Service. In this session we'll explore how UC as an end-user application can automatically program a SDN environment so that the network can self-adapt and provision itself to maximize the performance of real-time traffic like voice and video. Together with our partner HP Networking, you'll get to see exactly how Lync and the network work together to provide optimal quality across the enterprise network.
