The modern application server is a complex platform that is the linchpin of an enterprise environment that includes a very wide range of technologies-web document formatting, web protocols, server-side scripts, servlets, applets, programming languages, distributed object technologies, security capabilities, directory and naming services, load balancing, system management, and others. As such, it can be a daunting task to try to comprehend these systems. Application Servers for E-Business helps you understand the use of application servers in e-business. The book presents a comprehensive overview of the technologies related to application servers in their facilitation of E-business. These technologies include CORBA, Java, Enterprise Java Beans, Java 2, web servers, and legacy systems. It explores the role these servers play in the modern enterprise IT infrastructure and the environment in which they operate. The material also includes implementation considerations for application servers, including security, scalability, load balancing, and fault tolerance. Chapter one provides an overview of application servers, the evolution of computing that took us from hierarchical, mainframe-centric environments to the web model of computing, and the rationale for E-commerce and E-business. Chapters two through five cover specific technologies, from web browsers and servers to applets and servlets. Chapter three provides an overview of Java technologies, and chapter four covers CORBA. Chapter five discusses application servers in detail. Since application servers are increasingly supporting the key mission-critical processes of an enterprise, it is critical that organizations deploying them build in "enterprise-class" facilities for security, scalability, load balancing, fault tolerance, and management. Chapter six discusses these deployment design issues. The book concludes with chapter seven, a chapter that presents several examples of the advantages of application ser

Chapter six discusses these deployment design issues. The book concludes with chapter seven, a chapter that presents several examples of the advantages of application servers in large enterprises. It also presents two case studies that illustrate the decision process, and an overview of seventeen application servers. The chapters are organized in a straightforward manner, with section and subsections clearly indicated so that they can be easily skimmed. The comprehensive coverage offered in this book makes it an ideal reference for IT management and staff responsible for specifying, designing, evaluating, and implementing electronic commerce solutions.

Die Rontgendiagnostik des Herzens und der GefiiBe hat - in erster Linie infolge des Aufschwunges der Herz-und GefiiBchirurgie - in den letzten 20 Jahren an Bedeutung auBerordentlich gewonnen. Die Ausbildung neuer und die Verfeinerung bereits fruher bekannter Untersuchungsmethoden haben die diagnostischen Moglichkeiten in einem kaum geahnten MaBe erweitert, so daB der heutige Umfang des StofGBPes eine Dreiteilung des Bandes erforderlich machte, in dem die Rontgendiagnostik des Herzens und der GefiiBe handbuchmiiBig bearbeitet ist. Der dritte Teil dieses Bandes liegt nunmehr vor. Er umfaBt die Rontgendiagnostik der GefiiBe des kleinen Kreislaufs, der AbdominalgefiiBe (Aorta abdominalis und ihrer groBen Aste, Pfortadergebiet und Vena cava inferior), auBerdem die peripheren Arterien und Venen und schlieBIich die GehirngefiiBe und das Versorgungsgebiet der A. carotis externa. Wenn - dem Prinzip dieses Handbuches entsprechend - jeder Teilband in sich abgeschlossen sein solI, dann sind gewisse Uberschneidungen mit anderen Biinden un- vermeidbar. So wird natiirlich gerade die Gehirnangiographie im Rahmen der Neuro- radiologie eingehend abgehandelt; sie durfte trotzdem auch in diesem Teilband nicht fehlen. Ahnliche Uberschneidungen liegen aber auch bei anderen GefiiBbereichen in der Natur der Sache. So mussen, um nur noch ein Beispiel zu nennen, Kreislaufstorungen der Lunge sowohl hier als auch im Band uber die Lungendiagnostik besprochen werden. In dieser Tatsache sehen wir jedoch keinen Nachteil, eher vielIeicht sogar einen Vor- teil - vorausgesetzt, daB es gelingt, bei solchen Uberschneidungen die jeweilige Be- arbeitung dem Gesichtspunkt des betreGBPGBPenden Bandes oder Kapitels nach Art und Umfang anzugleichen.

The Scandinavian countries today form a security-community for economic cooperation and the settlement of international controversy by peaceful methods rather than by war. This status was achieved not while Norway and Sweden were amalgamated in a political union from 1814 to 1905, but only after separation. In this book Dr. Lindgren analyzes some of the forces underlying the failure and dissolution of the Norway-Sweden union. Originally published in 1959. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
