Accessing existing data

Previous modules have introduced DataSets and described how to use the XML Schema Definition Language (XSD) to define the structure of a DataSet. This module expands upon previous lessons by describing how you can use XSD and DataSets to access a data source.

GIS has been coming of age. Millions of people use one GIS or another every day, and with the advent of Web 2.0 we are promised GIS functionality on virtually every desktop and web-enabled cellphone. GIS knowledge, once restricted to a few insiders working with minicomputers that, as a category, don’t exist any more, has proliferated and is bestowed on students at just about every university and increasingly in community colleges and secondary schools.

This book will introduce you to one of the most important extensions to PHP that are available, starting with PHP version 5.0—the PHP Data Objects, commonly known as PDO. PHP grew in to a very popular web programming language due to its simplicity and ease of use. One of the key factors of this growing success is the built-in possibility to access many popular relational database management systems (RDBMS), such as MySQL, PostgreSQL, and SQLite, to name just a few.

This paper presents the design and implementation of DOT, a flexible architecture for data transfer. This architecture separates content negotiation from the data transfer itself. Applications determine what data they need to send and then use a new transfer service to send it. This transfer service acts as a common interface between applications and the lower-level network layers, facilitating innovation both above and below. The transfer service frees developers from re-inventing transfer mechanisms in each new application.

Citrix XenApp is the leader of application virtualization or application delivery. Several years ago, when the word Virtualization didn't exist, people used to talk about application hosting. Citrix was founded in 1989 and they developed the first successful product in 1993 called WinView. It provided remote access to DOS and Windows 3.1 applications on a multi-user platform. Citrix licensed Microsoft's Windows NT 3.51 source code from Microsoft; and in 1995 they shipped a multiuser version of Windows NT based on the MultiWin engine, known as WinFrame.

Thus, the study of mutual funds in emerging markets is overdue for those who need a fuller understanding of their investment conditions. In addition, this would allow an out-of- sample test to challenge existing asset pricing models and lead to the development of new empirical models. This study seeks to shed light on mutual fund investment in emerging markets and specifically focuses on three issues: performance, determinants of performance and the role of liquidity on performance and performance measure.

As service demand grows in metro networks, service providers need to be cost-conscious as they expand or evolve networks to meet new demands. They need to extend the value of installed systems, run more services on existing networks, and retain customers by offering on-demand access to a variety of services. And they want to reduce the cost of providing those services. SONET and SDH have been widely deployed by telephone companies and common carriers for more than a decade.

Immunization Immunizations are one of the most important tools we have to protect children from a wide range of diseases, including polio, measles, mumps, rubella, influenza, tetanus, diph- theria, and pertussis. Without immunizations, a much larger number of children in North America would die each year or live with the chronic effects of these diseases. Immunization coverage can also be an indicator of access to primary health care.

In this paper, the problem of analysis and design of large-scale multiple beamforming system is considered by system theory approach. We consider the response of system parameters by set of objective functions in a critical condition, which is unable to access measurement data or the data size is large. The reduced-order model is built and the robust solution is found for a multiple beamforming system. The Monte Carlo simulation results show that the proposed multiple beamforming system yields significant performance against over existing methods.

OpenSSH is an open-source implementation of the SSH (Secure SHell) protocols, originally developed in 1995 by Tatu Ylönen. SSH-based tools provide secure client/server connections and are usually designed to replace older remote-access tools like rsh and telnet. Unlike their predecessors, SSH-based tools encrypt their transmissions, making it difficult or impossible for intruders to “sniff” important information, such as passwords, from the data stream. SSH implementations exist for every major platform including Microsoft Windows. This paper will focus on the OpenSSH implementation....

The main purpose of a computer system is to execute programs. These programs, together with the data they access, must be in main memory (at least partially) during execution. To improve both the utilization of the CPU and the speed of its response to users, the computer must keep several processes in memory. Many memory-management schemes exist, reflecting various
