При стремительном росте устройств с touch-дисплеями уже стыдно не думать о пользователе, как о человеке с руками. Мы разберем основные принципы, которым нужно следовать при проектировании интерфейсов, рассмотрим элементы интерфейса, которые должны быть адаптированы под пальцы человеческих рук. Доклад будет особенно полезен тем, кто все и так прекрасно знает.
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.
You may think that there is much in SQL Server that appears to work as if by magic? And you would be right! But despite this magic, everything is actually quite easy to understand. This 500-level report contains information about the internal data storage format in SQL Server (MDF files), as well as about how you can work with the data using only a hex editor. You will learn about how SQL Server stores internal metadata for objects and about how you can find and read the data on the disk.
In this session we cover different aspects of Hyper-V Recovery Manager, an enterprise-scale Disaster Recovery solution to provide a single click failover in case of disaster (e.g., automation of overall DR workflow using with sequencing, manual actions, etc. to provide both application and site level DR). We cover the most frequently asked end-point support from our customers: Azure to help save precious CAPEX. Learn how to enable Azure as a Disaster Recovery point in a secure manner and seamless management of failover, failback type activities using Azure IaaS VM. Network connection—back to datacenter and to the clients—is one of the top challenges in setup of your DR infrastructure and we cover how to simplify networking for disaster recovery setup. The session also covers enhancements to the solution for the private datacenter to the private datacenter scenario.
