Sommario/riassunto |

Middleware is the bridge that connects distributed applications across different physical locations, with different hardware platforms, network technologies, operating systems, and programming languages. This book describes middleware from two different perspectives: from the viewpoint of the systems programmer and from the viewpoint of the applications programmer. It focuses on the use of open source solutions for creating middleware and the tools for developing distributed applications. The design principles presented are universal and apply to all middleware platforms, including CORBA and W |

Sommario/riassunto |

The World Wide Web has now been in use for more than 20 years. From early browsers to today's principal source of information, entertainment and much else, the Web is an integral part of our daily lives, to the extent that some people believe 'if it's not online, it doesn't exist.' While this statement is not entirely true, it is becoming increasingly accurate, and reflects the Web's role as an indispensable treasure trove. It is curious, therefore, that historians and social scientists have thus far made little use of the Web to investigate historical patterns of culture and society, despite. |
