This overview article explores the implications of big data in education, focusing by way of example on data generated by student writing. We have chosen writing because it presents particular complexities, highlighting the range of processes for collecting and interpreting evidence of learning in the era of computer-mediated instruction and assessment as well as the challenges.

Information System Development and Database Development In many organizations, database development from the beginning of enterprise data modeling, data modeling enterprises determine the scope of the database and the general content. This step usually occurs in an organizations information system planning process, it aims to help organizations create an overall data description or explanation, and not the design of a specific database. A specific database for one or more information systems provide data and the corporate data model (which may involve a number of databases) described by the organization maintaining the scope of the data. Data modeling in the enterprise, you review of the current system, the need to support analysis of the nature of the business areas, the need for further description of the abstract data, and planning one or more database development project. Figure 1 shows Pine Valley furniture companys enterprise data model of a part. 1.1 Information Syste

CHAPTER 1 Android Overview In this chapter, you will learn how Android came about. Wersquo;ll take a look at its history to help us understand its future. As this mobile environment enters a make-or-break year, we look at the key players in this ecosystem, what motivates them, and what strengths and weaknesses they bring to the table. By the end of this chapter, you will better understand the ecosystem from a business point of view, which should help clarify the technology choices and how they relate to long-term advantages for various platforms. Android Overview Android is a comprehensive open source platform designed for mobile devices. It is championed by Google and owned by Open Handset Alliance. The goal of the alliance is to “accelerate innovation in mobile and offer consumers a richer, less expensive, and better mobile experience.” Android is the vehicle to do so. As such, Android is revolutionizing the mobile space. For the first time, it is a tru

Hello Android Chapter 1 Quick Start Android combines the ubiquity of cell phones, the excitement of open source software, and the corporate backing of Google and other Open Handset Alliance members like Intel, TI, T-Mobile, and NTT DoCoMo. The result is a mobile platform you canrsquo;t afford not to learn. Luckily, getting started developing with Android is easy. You donrsquo;t even need access to an Android phone—just a computer where you can install the Android SDK and phone emulator. In this chapter, Irsquo;ll show you how to get all the development tools installed, and then wersquo;ll jump right in and create a working application: Androidrsquo;s version of “Hello, World.” 1.1 Installing the Tools The Android software development kit (SDK) works on Windows, Linux, and Mac OS X. The applications you create, of course, can be deployed on any Android devices. Before you start coding, you need to install Java, an IDE, and the Android SDK. Ja

A point xo euro; E C lR is called a local maximum (resp. local minimum) and the value of a function f : E →R at that point a local maximum value (resp. local minimum value) if there exists a neighborhod UE(xo) of xo in E suchthat at an pointxeuro;UE(xo)we have : Definition 2 If the strict inequality f(x)0 lt; f(xo) (resp. f(x) gt; f(xo)) holds at every point x euro; UE (xo) xo = UE(xo), the point xo is called strict local maximum (resp. strict local minimum) and the value of the function f : E →R a strict local maximum value (resp. strict local minimum value). Definition 3. The local maxima and minima are called local extrema and the values of the function at these points local extreme values of the function. EXAMPLE 1. . (see Fig. 5.8). For this function x = - 1 is a strict local maximum; x = 0 is a strict local minimum;
