Providing key information on how to work with research data, Introduction to Data Technologies presents ideas and techniques for performing critical, behind-the-scenes tasks that take up so much time and effort yet typically receive little attention in formal education. With a focus on computational tools, the book shows readers how to improve their awareness of what tasks can be achieved and describes the correct approach to perform these tasks. Practical examples demonstrate the most important points The author first discusses how to write computer code using HTML as a concrete example. He then covers a variety of data storage topics, including different file formats, XML, and the structure and design issues of relational databases. After illustrating how to extract data from a relational database using SQL, the book presents tools and techniques for searching, sorting, tabulating, and manipulating data. It also introduces some very basic programming concepts as well as the R language for statistical computing. Each of these topics has supporting chapters that offer reference material on HTML, CSS, XML, DTD, SQL, R, and regular expressions. One-stop shop of introductory computing information Written by a member of the R Development Core Team, this resource shows readers how to apply data technologies to tasks within a research setting. Collecting material otherwise scattered across many books and the web, it explores how to publish information via the web, how to access information stored in different formats, and how to write small programs to automate simple, repetitive tasks.

Introduction to Data Networks describes the different types of data networks, how they operate and the services they can provide.Data networks are telecommunications networks that are installed and operated for information exchange between data communication devices such as computers and voice gateways. Although data networks can transfer any type of digital media (voice, data or video), the type of network, services used and optional configurations can dramatically affect the performance of data services.This book provides a functional description of the key data network parts including hubs, routers, bridges and gateways. You will discover the differences between personal area networks (PANs), premises distribution networks (PDNs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs).The basic operation of Ethernet is provided along with how Ethernet has evolved and the different types of Ethernet systems that are available today. Discover how data networks are configured and managed using simple network management protocol (SNMP). Learn the basic operation of gateways and firewalls and how firewalls operate to protect networks from the unwanted transmission of information. The operation of different types of data systems and how they operate is explained including Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay, and the Internet. Find out how data networks can be configured to allow many users to share the same data network using virtual private networks. You will lean about the common types of data services such as CBR, ABR, UBR and their typical service costs. Some of the most important topics featured are:?Functional parts of data networks ?Descriptions of hubs, routers, bridges and gateways.?The differences between PAN, PDN, LAN, MAN, and WAN Networks?How Ethernet and other types of data networks operate?How packets are automatically routed in IP networks?How gateways and firewalls operate?Overviews of Ethernet, Token Ring, FDDI, PON, ATM, Frame Relay and the Internet?Introduction to virtual networks (VPNs)?Data services including CBR, ABR and UBR

Web technologies are increasingly relevant to scientists working with data, for both accessing data and creating rich dynamic and interactive displays. The XML and JSON data formats are widely used in Web services, regular Web pages and JavaScript code, and visualization formats such as SVG and KML for Google Earth and Google Maps. In addition, scientists use HTTP and other network protocols to scrape data from Web pages, access REST and SOAP Web Services, and interact with NoSQL databases and text search applications. This book provides a practical hands-on introduction to these technologies, including high-level functions the authors have developed for data scientists. It describes strategies and approaches for extracting data from HTML, XML, and JSON formats and how to programmatically access data from the Web. Along with these general skills, the authors illustrate several applications that are relevant to data scientists, such as reading and writing spreadsheet documents both locally and via Google Docs, creating interactive and dynamic visualizations, displaying spatial-temporal displays with Google Earth, and generating code from descriptions of data structures to read and write data. These topics demonstrate the rich possibilities and opportunities to do new things with these modern technologies. The book contains many examples and case-studies that readers can use directly and adapt to their own work. The authors have focused on the integration of these technologies with the R statistical computing environment. However, the ideas and skills presented here are more general, and statisticians who use other computing environments will also find them relevant to their work. Deborah Nolan is Professor of Statistics at University of California, Berkeley. Duncan Temple Lang is Associate Professor of Statistics at University of California, Davis and has been a member of both the S and R development teams.

Managing Data in Motion describes techniques that have been developed for significantly reducing the complexity of managing system interfaces and enabling scalable architectures. Author April Reeve brings over two decades of experience to present a vendor-neutral approach to moving data between computing environments and systems. Readers will learn the techniques, technologies, and best practices for managing the passage of data between computer systems and integrating disparate data together in an enterprise environment. The average enterprise's computing environment is comprised of hundreds to thousands computer systems that have been built, purchased, and acquired over time. The data from these various systems needs to be integrated for reporting and analysis, shared for business transaction processing, and converted from one format to another when old systems are replaced and new systems are acquired. The management of the "data in motion" in organizations is rapidly becoming one of the biggest concerns for business and IT management. Data warehousing and conversion, real-time data integration, and cloud and "big data" applications are just a few of the challenges facing organizations and businesses today. Managing Data in Motion tackles these and other topics in a style easily understood by business and IT managers as well as programmers and architects. Presents a vendor-neutral overview of the different technologies and techniques for moving data between computer systems including the emerging solutions for unstructured as well as structured data types Explains, in non-technical terms, the architecture and components required to perform data integration Describes how to reduce the complexity of managing system interfaces and enable a scalable data architecture that can handle the dimensions of "Big Data"
