Large corporations like IBM and Oracle are using Excel dashboards and reports as a Business Intelligence tool, and many other smaller businesses are looking to these tools in order to cut costs for budgetary reasons. An effective analyst not only has to have the technical skills to use Excel in a productive manner but must be able to synthesize data into a story, and then present that story in the most impactful way. Microsoft shows its recognition of this with Excel. In Excel, there is a major focus on business intelligence and visualization. Data Visualization with Excel Dashboards and Reports fills the gap between handling data and synthesizing data into meaningful reports. This title will show readers how to think about their data in ways other than columns and rows.
Most Excel books do a nice job discussing the individual functions and tools that can be used to create an "Excel Report". Titles on Excel charts, Excel pivot tables, and other books that focus on "Tips and Tricks" are useful in their own right; however they don't hit the mark for most data analysts. The primary reason these titles miss the mark is they are too focused on the mechanical aspects of building a chart, creating a pivot table, or other functionality. They don't offer these topics in the broader picture by showing how to present and report data in the most effective way.
What are the most meaningful ways to show trending? How do you show relationships in data?

This book includes dozens of real-life complex Enterprise IT problems and how they were resolved. This book was also designed to support a college course developed and taught by the authors. In support of this course, the authors created a set of tools that are collectively called “Clouducate”. Clouducate includes Amazon Web Service Command Line Interface scripts (AWL/CLI), and .NET code to create an environment (basically a small datacenter – AWS Virtual Private Cloud) whereby the skills taught in this book could be exercised. There are also custom assignments that break these applications such that the student can work at resolving the problem in a simulation of what happens in real Enterprise IT shops. These tools are freely available for download and explained in the final chapter.

Windows 10 is the engine that powers all of those next-generation devices, as well as the large population of the traditional personal computers (PC), designs that are in use today. On a touchscreen, you swipe and tap to interact with objects on the screen and use an onscreen keyboard to enter and edit text. For devices with detachable keyboards, Windows 10 includes unique features designed to ease the transition between the traditional PC way of working and the new Tablet Mode. In the case of PCs that aren’t touch- enabled, Windows 10 offers the familiar keyboard-and-mouse experience, with no compromises. We offer details on how to master the new user experience on traditional PCs and touchscreen-equipped devices in Chapter 3, “Using Windows 10.” Our coverage of customization options is in Chapter 4, “Personalizing Windows 10.” The new generation of hardware isn’t just defined by just peripheral features anymore. Modern devices designed for Windows 10 incorporate new features that enhance the security of the startup process. If you’ve mastered the ins and outs of BIOS setup on a legacy PC, you need to learn how to configure its replacement, the Unified Extensible Firmware Interface (UEFI). That hardware design, in turn, enables an additional security feature called Secure Boot, which protects your Windows 10 PC from an insidious form of...
