GENERAL AND REUSABLE COMPONENTS FOR DEFINING NET-CENTRIC APPLICATION PROGRAM ARCHITECTURES

摘要

A robust toolkit provides facilities that can be assembled in a modular mann er to specify the fundamental architecture of a net-centric application. A bootstrapping process assembles various facilities within the architecture. A configuration facility defines an API for getting properties that can be defined in any number of different types of sources. A factory de-couples ho w a resource is produced from where the resource is used. A selector framework applies standard query language to contexts other than querying a database. A pipeline architecture defines a model view controller-like framework for a processing pipeline. Selectors are used to specify when certain portions of a Web conversation should be made available to a user. An authorization facili ty associates permissions with a user to specify which portions of an applicati on a user is authorized to use.
